Background Info
I have a maximum of 15 hours available for work Monday – Friday.
Each day, from Monday – Thursday, I will work a random amount of
hours between 0 – 8.
I can work 0 hours on Monday - Thursday.
On Friday, I will work whatever hours are left from the maximum of 15
hours available.
I must work at least 1 hour on Friday.
Formulas Used
(Cell: C4) Monday: RANDBETWEEN(0-8)
(Cell: D4) Tuesday: RANDBETWEEN(0-8)
(Cell: E4) Wednesday: RANDBETWEEN(0-8)
(Cell: F4) Thursday: RANDBETWEEN(0-8)
(Cell: G4) Friday: 15 – SUM(C4:F4)
Total Hours: SUM(C4:G4)
Issues
The Friday cell will occasionally receive a negative number of hours
worked.
Example Output of Issue
Output
Current Workaround
Update the values generated by RANDBETWEEN by pressing ‘DEL’ on an
empty cell. This forces all the values to change.
Repeat until a positive value is received in the cell for Friday
Google Sheet Settings
Goal
Have the cells update themselves automatically IF a negative value is received in the cell for Friday
Possible Solution/Thoughts
Is there a way to force RANDBETWEEN numbers to update via a formula?
If yes, is there a way to setup a WHILE loop that will update the
RANDBETWEEN values UNTIL the cell for Friday has a positive number?
Is there a way to have a script run on specific cells? The intent is to simulate data for variations on a work schedule.
I did try to accomplish this via a script but wasn’t able to get the cells to update correctly and other times it would not update at all.
function randomTotal()
{
var Monday = SpreadsheetApp.getActiveSheet().getRange('C4');
var Tuesday = SpreadsheetApp.getActiveSheet().getRange('D4');
var Wednesday = SpreadsheetApp.getActiveSheet().getRange('E4');
var Thursday = SpreadsheetApp.getActiveSheet().getRange('F4');
var Friday = SpreadsheetApp.getActiveSheet().getRange('G4');
var FridayValue = SpreadsheetApp.getActiveSheet().getRange('G4').getValue();
while(FridayValue < 0)
{
newTotal(Monday,Tuesday,Wednesday,Thursday,Friday);
FridayValue = SpreadsheetApp.getActiveSheet().getRange('G4').getValue();
}
}
function newTotal(Monday,Tuesday,Wednesday,Thursday,Friday)
{
Monday.setFormula('=RANDBETWEEN(0,8)');
Tuesday.setFormula('=RANDBETWEEN(0,8)');
Wednesday.setFormula('=RANDBETWEEN(0,8)');
Thursday.setFormula('=RANDBETWEEN(0,8)');
Friday.setFormula('=15-SUM(C4:F4)');
}
This can actually be accomplished without Google Apps Script. I would suggest the following formulas for cell D4
=RANDBETWEEN(0,IF(SUM($C4:C4)<=6,8,14-SUM($C4:C4)))
You can then copy/paste this from D4 into E4 and F4 (the formula references will work), and keep C4 and G4 as is. That should do the trick!
You absolutely can accomplish this programmatically, but in general, if it's possible to do without, that's usually the simpler approach.
For a quick explanation of why this works: if the cells to the left sum to <=6, then you can always add up to 8 hours, because it leaves you in the range of <= 14 total. But, if that's not the case, you want to subtract however many hours you already have from 14, as 14 is the max you can have on Mon - Thurs, and get the remaining of at least 1 on Friday.
While majorly overcomplicated given the other answer provided, I did go in and create a script for this.
Here is the code:
function setSame() {
console.log('Start check');
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheetMaster = ss.getSheetByName("Sheet2");
var sortRange = sheetMaster.getRange('B3:E3');
var forms = ['=RANDBETWEEN(0,8)','=RANDBETWEEN(0,8)','=RANDBETWEEN(0,8)','=RANDBETWEEN(0,8)'];
sortRange.setValues([forms]);
var mon = sheetMaster.getRange('B3').getValue();
sortRange.getCell(1,1).setValue(mon);
var tues = sheetMaster.getRange('C3').getValue();
sortRange.getCell(1,2).setValue(tues);
var wed = sheetMaster.getRange('D3').getValue();
sortRange.getCell(1,3).setValue(wed);
var thurs = sheetMaster.getRange('E3').getValue();
sortRange.getCell(1,4).setValue(thurs);
var fri = sheetMaster.getRange('F3').getValue();
console.log('Monday: '+mon);
console.log('Tuesday: '+tues);
console.log('Wednesday: '+wed);
console.log('Thursday: '+thurs);
console.log('Friday: '+fri);
if(fri < 1) {
console.log("less");
setSame();
}
}
Sheet
The setSame() function is set up with an onChange trigger (Triggers > Add Trigger). The console.log() lines are there for debugging purposes, and are not necessary.
I am sure there are better ways to go about this with a script, but this was the quickest way I could think to solve this.

I'm trying to get from a time formatted Cell (hh:mm:ss) the hour value, the values can be bigger 24:00:00 for example 20000:00:00 should give 20000:
Table:
if your read the Value of E1:
var total = sheet.getRange("E1").getValue();
Logger.log(total);
The result is:
Sat Apr 12 07:09:21 GMT+00:09 1902
Now I've tried to convert it to a Date object and get the Unix time stamp of it:
var date = new Date(total);
var milsec = date.getTime();
Logger.log(Utilities.formatString("%11.6f",milsec));
var hours = milsec / 1000 / 60 / 60;
Logger.log(hours)
1374127872020.000000
381702.1866722222
The question is how to get the correct value of 20000 ?
Expanding on what Serge did, I wrote some functions that should be a bit easier to read and take into account timezone differences between the spreadsheet and the script.
function getValueAsSeconds(range) {
var value = range.getValue();
// Get the date value in the spreadsheet's timezone.
var spreadsheetTimezone = range.getSheet().getParent().getSpreadsheetTimeZone();
var dateString = Utilities.formatDate(value, spreadsheetTimezone,
'EEE, d MMM yyyy HH:mm:ss');
var date = new Date(dateString);
// Initialize the date of the epoch.
var epoch = new Date('Dec 30, 1899 00:00:00');
// Calculate the number of milliseconds between the epoch and the value.
var diff = date.getTime() - epoch.getTime();
// Convert the milliseconds to seconds and return.
return Math.round(diff / 1000);
}
function getValueAsMinutes(range) {
return getValueAsSeconds(range) / 60;
}
function getValueAsHours(range) {
return getValueAsMinutes(range) / 60;
}
You can use these functions like so:
var range = SpreadsheetApp.getActiveSheet().getRange('A1');
Logger.log(getValueAsHours(range));
Needless to say, this is a lot of work to get the number of hours from a range. Please star Issue 402 which is a feature request to have the ability to get the literal string value from a cell.
There are two new functions getDisplayValue() and getDisplayValues() that returns the datetime or anything exactly the way it looks to you on a Spreadsheet. Check out the documentation here
The value you see (Sat Apr 12 07:09:21 GMT+00:09 1902) is the equivalent date in Javascript standard time that is 20000 hours later than ref date.
you should simply remove the spreadsheet reference value from your result to get what you want.
This code does the trick :
function getHours(){
var sh = SpreadsheetApp.getActiveSpreadsheet();
var cellValue = sh.getRange('E1').getValue();
var eqDate = new Date(cellValue);// this is the date object corresponding to your cell value in JS standard
Logger.log('Cell Date in JS format '+eqDate)
Logger.log('ref date in JS '+new Date(0,0,0,0,0,0));
var testOnZero = eqDate.getTime();Logger.log('Use this with a cell value = 0 to check the value to use in the next line of code '+testOnZero);
var hours = (eqDate.getTime()+ 2.2091616E12 )/3600000 ; // getTime retrieves the value in milliseconds, 2.2091616E12 is the difference between javascript ref and spreadsheet ref.
Logger.log('Value in hours with offset correction : '+hours); // show result in hours (obtained by dividing by 3600000)
}
note : this code gets only hours , if your going to have minutes and/or seconds then it should be developped to handle that too... let us know if you need it.
EDIT : a word of explanation...
Spreadsheets use a reference date of 12/30/1899 while Javascript is using 01/01/1970, that means there is a difference of 25568 days between both references. All this assuming we use the same time zone in both systems. When we convert a date value in a spreadsheet to a javascript date object the GAS engine automatically adds the difference to keep consistency between dates.
In this case we don't want to know the real date of something but rather an absolute hours value, ie a "duration", so we need to remove the 25568 day offset. This is done using the getTime() method that returns milliseconds counted from the JS reference date, the only thing we have to know is the value in milliseconds of the spreadsheet reference date and substract this value from the actual date object. Then a bit of maths to get hours instead of milliseconds and we're done.
I know this seems a bit complicated and I'm not sure my attempt to explain will really clarify the question but it's always worth trying isn't it ?
Anyway the result is what we needed as long as (as stated in the comments) one adjust the offset value according to the time zone settings of the spreadsheet. It would of course be possible to let the script handle that automatically but it would have make the script more complex, not sure it's really necessary.
For simple spreadsheets you may be able to change your spreadsheet timezone to GMT without daylight saving and use this short conversion function:
function durationToSeconds(value) {
var timezoneName = SpreadsheetApp.getActive().getSpreadsheetTimeZone();
if (timezoneName != "Etc/GMT") {
throw new Error("Timezone must be GMT to handle time durations, found " + timezoneName);
}
return (Number(value) + 2209161600000) / 1000;
}
Eric Koleda's answer is in many ways more general. I wrote this while trying to understand how it handles the corner cases with the spreadsheet timezone, browser timezone and the timezone changes in 1900 in Alaska and Stockholm.
Make a cell somewhere with a duration value of "00:00:00". This cell will be used as a reference. Could be a hidden cell, or a cell in a different sheet with config values. E.g. as below:
then write a function with two parameters - 1) value you want to process, and 2) reference value of "00:00:00". E.g.:
function gethours(val, ref) {
let dv = new Date(val)
let dr = new Date(ref)
return (dv.getTime() - dr.getTime())/(1000*60*60)
}
Since whatever Sheets are doing with the Duration type is exactly the same for both, we can now convert them to Dates and subtract, which gives correct value. In the code example above I used .getTime() which gives number of milliseconds since Jan 1, 1970, ... .
If we tried to compute what is exactly happening to the value, and make corrections, code gets too complicated.
One caveat: if the number of hours is very large say 200,000:00:00 there is substantial fractional value showing up since days/years are not exactly 24hrs/365days (? speculating here). Specifically, 200000:00:00 gives 200,000.16 as a result.
I am learning right now scripts functionally in Google Sheet, however, can't twist my head around constructing a very simple App script.
I have the following table (Snoopi Tab)
https://docs.google.com/spreadsheets/d/1l6nYBAqB1GWoMkIOwlykhiuMpaXdWHTo7UhgZdq6hT8/edit?usp=sharing
I want it to do this simple action:
EXAMPLE: If today is not Sunday or Saturday and the date is 14.2.14 and cell BF5 is
---> go down 3 rows and paste current time "Clocking in" working-shift
When button "IN" is clicked:
If (TODAYDATE = Value in cell in row 5) & (row 3 ==!"S") both true
Set current time in (same column just row 8)
Same with "OUT" button, but this I'll try to figure by myself.
The other answer is acceptable, but is very resource intensive and have a lot of loops to do resulting to very slow execution time especially when it gets later on the year since it will loop all those dates.
Also, the run you did on the other answer did finish successfully but didn't write anything due to it missing the actual date value. This might have been caused by a timezone issue, or by only modifying the actual date while getting the raw time of the cell value.
A better alternative would be to make use of the 4th row where it contains x value when the date is equal to the current date. By using that, you wouldn't need to loop thus resulting in faster execution time and wouldn't need to convert time thus making it safer. As long as row 4 is populated on all columns (which your problem is), there should be no issue of using this script.
Script:
function WorkClock() {
var currentDate = new Date();
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = SpreadsheetApp.getActiveSheet();
// you only need 3rd and 4th row of data
var data = sheet.getRange("E3:NE4").getValues();
// 4th row contains 'x' when today matches the column, find that index
var indexToday = data[1].indexOf('x');
// if that column's row 3 is not 'S'
if(data[0][indexToday] != 'S')
// write the time on row 8
sheet.getRange(8, indexToday + 5).setValue(Utilities.formatDate(currentDate, ss.getSpreadsheetTimeZone(), 'HH:mm'));
}
Output:
Note:
Timezone used is based on the spreadsheet's timezone which is GMT-8. Wherever the user is, it will use GMT-8, not its local time which should be helpful in some cases.
Performance difference between this and looping all dates would be vast if we are now dealing with the later months of the year (e.g. November, December)
For the OUT button, create another function by duplicating the current function. Then replace where you write the time. Instead of row 8 (Start), write it in row 10 (Finish).
function myFunction() {
var actualDate = new Date(new Date().setHours(0, 0, 0, 0)).getTime();
var sheet = SpreadsheetApp.getActiveSheet();
var data = sheet.getRange("E3:NE6").getValues();
for(var i = 0; i < data[0].length; i++) {
if (data[2][i].getTime() === actualDate) {
if (data[0][i] !== "S") {
sheet.getRange(8, (5+i)).setValue(new Date().getHours() + ":" + new Date().getMinutes());
}
break;
}
}
}
I'm about to use google sheet as my database for my android app small project. I'm using Google Script to handle the request from my app.
In my google sheet, I store;
A2:A = date as dd/mm/yyyy e.g 21/12/2019 but
the display format is dd-MMM e.g 21-Dec
C2:D = time as hh:mm:ss e.g 21:00:00 but
the display format is hh:mm e.g 21:00
Yes, I need a different format for the display and input.
My google sheet:
When I use google script to get a value of the cell, it seems that it is reformatted
the date looks like this: Sat Jan 01 2019 00:00:00 GMT+0700 (ICT)
the time the other hand, change in value a bit. 20:00:00 to 19:52:48
Is there any function to get cell real values as text without being reformatted?
The only thing that I can think of is instead of using getValues(), I can use getDisplayValues(). The values will not be reformatted, but it is not a solution for me, as it will take the display format.
Snippet of my code:
function updateData(e, sheet) {
var tgl = e.parameter.tgl;
var dtg = e.parameter.dtg;
var plg = e.parameter.plg;
var lbr = e.parameter.lbr;
var rangeHead = sheet.getRange("A2:A");
var valuesHead = rangeHead.getValues();
var rangeFirst = sheet.getRange("C2:D")
var valuesFirst = rangeFirst.getValues();
var rangeSecond = sheet.getRange("G2:G")
var valuesSecond = rangeSecond.getValues();
for (var i = 0; i < valuesHead.length; i++) {
if (valuesHead[i][0] === tgl) {
if(dtg!="null") { valuesFirst[i][0] = dtg; }
if(plg!="null") { valuesFirst[i][1] = plg; }
if(lbr!="null") { valuesSecond[i][0] = lbr; }
break;
}
}
rangeFirst.setValues(valuesFirst);
rangeSecond.setValues(valuesSecond);
}
The code won't work as I will comparing 21/12/2019 with Sat Jan 01 2019 00:00:00 GMT+0700 (GMT).
[UPDATE 1]:
Thank you P-Burke for the enlightenment. Now, I have an idea to solve the date problem. I know that the script pulls the date as date object, but I am unaware that it also saves as a date object. (hehe my bad) I don't realize it as there is no autocomplete when I call values[0][0]. of course, as it recognizes the object type at the run time.
So, my workaround will be; I will call getDate, getMonth+1, and getYear. After that, I will compare with my parameter freely.
Though, the time cell still a bit confusing for me. the time offset is 18 minutes 12 seconds. I don't think it's because of timezone different and my computer clock. the timezone different is too big and I 've made sure that the script, spreadsheet, and local timezone all the same. My computer clock is also only a minute less behind.
[UPDATE 2]:
Alright, enough with the confusion. It seemed that the script converts the time to Date object respect to my local timezone. I got this answer from another thread. So, actually, my local timezone changes many times and some of them have offset smaller than hours unit (one of the timezones used in my area is UTC +7:07:12h). The only source documenting those changes I could find is from https://www.timeanddate.com/time/zone/indonesia/jakarta. Finally, I gave up. For my goodness sake, I will just use getDisplayValue and ignore the seconds. Unless you guys have any other workaround, I will be so grateful.
Thank you once again to the community.
Firstly, and I don't know if this is related to your issue, but the spreadsheet and the script each have their own timezone setting:
Spreadsheet: File >> Spreadsheet Settings >> Time Zone.
Script: File >> Project Properties >> Time Zone.
And if these are different that can lead to confusion. One answer, if all your users are in the same timezone, is to set them to the same. Alternatively these can be determined from within your script as described here, and logic included to handle any differences. I don't understand the few minutes time difference, perhaps your PC clock is inaccurate?
The other point, which I think is more relevant to your question is that you effectively have multiple date/time formats in play. The picture below shows that in the spreadsheet times are edited in one format (02/01/2019 09:00:00), but displayed in whatever format is defined for the cell using the format menu. Yet when the cell values are pulled into a script using getValues() and displayed they appear as follows: Values: [[Thu Jan 31 09:00:00 GMT+00:00 2019, Wed Jan 02 09:00:00 GMT+00:00 2019]].
Yet in the code below, values[0][0] and values[0][1] are actually JavaScript Date() objects and can be compared in the usual way, alternatively they can be reformatted into whatever string format you require as illustrated in the code below:
function myFunction() {
var ss = SpreadsheetApp.getActive();
var ws = ss.getActiveSheet();
var input_range = ws.getRange("A1:B1");
var values = [];
values = input_range.getValues(); // Returns a multi-dimensional array, hence [0][0] to access.
Logger.log("Values: %s", values);
// As Date() objects the usual methods are available.
Logger.log("Date().getMonth(): %s",values[0][0].getMonth());
Logger.log("Date().getYear(): %s",values[0][1].getYear());
// This formats the date as Greenwich Mean Time in the format
// year-month-dateThour-minute-second.
var formattedDate = Utilities.formatDate(values[0][0], "GMT", "yyyy-MM-dd'T'HH:mm:ss'Z'");
Logger.log(formattedDate);
formattedDate = Utilities.formatDate(values[0][1], "GMT", "yyyy-MM-dd'T'HH:mm:ss'Z'");
Logger.log(formattedDate);
}
Logger.log output:
[19-01-31 11:43:17:635 GMT] Values: [[Thu Jan 31 09:00:00 GMT+00:00 2019, Wed Jan 02 09:00:00 GMT+00:00 2019]]
[19-01-31 11:43:17:636 GMT] Date().getMonth(): 0.0
[19-01-31 11:43:17:637 GMT] Date().getYear(): 2019.0
[19-01-31 11:43:17:638 GMT] 2019-01-31T09:00:00Z
[19-01-31 11:43:17:638 GMT] 2019-01-02T09:00:00Z
I want to solve this problem in simplest way.
How to daily increment value in specified cell or range of cells. For exemple in cell 'A1' i insert today value 15. Tommorow this value will be 16, day after tommorow 17 etc.
I dont think anything exists which will automatically go in to your spreadsheets and fiddle with your values. But you can use a formula based on some start date:
=DATEDIF(DATE(2015, 1, 6), TODAY(), "D")
This will calculate how many days there have been since 2015 Jan 6. Today for me the answer is 15, and tomorrow it will be 16.
Another option is to add a time trigger or an onOpen() trigger to your spreadsheet. When you open your spreadsheet, the function would check the cell you are incrementing, get the last value, check if the last value is the value for the current day, and if it isn't add a new value.
function onOpen() {
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var sheet = spreadsheet.getSheets()[0];
var cellValue = sheet.getRange("A1");
var theDate = new Date().getDay();
Logger.log('theDate: ' + theDate);
var todaysNumber = theDate;
if (cellValue != todaysNumber) {
cellValue.setValue(todaysNumber);
};
};
Please try in A1:
=now()-42010
format as number, no decimals and in File, Spreadsheet settings... ensure Recalculation: is set to On change and something.
I have a form which activates a procedure via an "On form submit" trigger. At the end of this routine I want to insert the difference in time between the form's Timestamp and the current time at the end of the routine (the difference of which is only a matter of a few seconds).
I've tried many things so far, but the result I typically receive is NaN.
I thought that my best bet would be to construct the runtime elements (H,M,S) and similarly deconstruct the time elements from the entire Timestamp, and then perform a bit of math on that:
var rt_ts = Math.abs(run_time - ts_time);
(btw, I got that formula from somewhere on this site, but I'm obviously grasping at anything at this point. I just can't seem to find a thread where my particular issue is addressed)
I've always found that dealing with dates and time in Javascript is tricky business (ex: the quirk that "month" start at zero while "date" starts at 1. That's unnecessarily mind-bending).
Would anyone care to lead me out of my current "grasping" mindset and guide me towards something resembling a logical approach?
You can simply add this at the top of your onFormSubmit routine :
UserProperties.setProperty('start',new Date().getTime().toString())
and this at the end that will show you the duration in millisecs.
var duration = new Date().getTime()-Number(UserProperties.getProperty('start'))
EDIT following your comment :
the time stamp coming from an onFormSubmit event is the first element of the array returned by e.values see docs here
so I don't really understand what problem you have ??
something like this below should work
var duration = new Date().getTime() - new Date(e.values[0]).getTime();//in millisecs
the value being a string I pass it it 'new Date' to make it a date object again. You can easily check that using the logger like this :
Logger.log(new Date(e.values[0]));//
It will return a complete date value in the form Fri Mar 12 15:00:00 GMT+01:00 2013
But the values will most probably be the same as in my first suggestion since the TimeStamp is the moment when the function is triggered...
I have a function which can show the times in a ss with timestamps in column A. It will also add the time of the script itself to the first timestamp (in row 3) and show this in the Log.
Notice that the google spreadsheet timestamp has a resolution in seconds and the script timestamp in milliseconds. So if you only add, say, 300 milliseconds to a spreadsheet timestamp, it might not show any difference at all if posted back to a spreadsheet. The script below only takes about 40 milliseconds to run, so I have added a Utilities.sleep(0) where you can change the value 0 to above 1000 to show a difference.
function testTime(){
var start = new Date().getTime();
var values = SpreadsheetApp.getActiveSheet().getDataRange().getValues();
for(var i = 2; i < values.length ; i++){
Logger.log(Utilities.formatDate(new Date(values[i][0]),Session.getTimeZone(),'d MMM yy hh:mm:ss' )); // this shows the date, in my case same as the ss timestamp.
Logger.log( new Date(values[i][0]).getTime() ); // this is the date in Milliseconds after 1 Jan 1970
}
Utilities.sleep(0); //you can vary this to see the effects
var endTime = new Date();
var msCumulative = (endTime.getTime() - start);
Logger.log(msCumulative);
var msTot = (msCumulative + new Date(values[2][0]).getTime());
Logger.log('script length in milliseconds ' + msTot );
var finalTime = Utilities.formatDate(new Date(msTot), Session.getTimeZone(), 'dd/MM/yyyy hh:mm:ss');
Logger.log ( finalTime); //Note that unless you change above to Utilities.sleep(1000) or greater number , this logged date/time is going to be identical to the first timestamp since the script runs so quickly, less than 1 second.
}
