Date picker for Calender to Sheets Script - google-apps-script

Question

Below is a script I found and modified to track events by grabbing event information from our Calendar(s) and populating a spreadsheet (with mild reformatting) based on a selected date range.
Currently I have to manually change the dates within the script each week to get the events that I need. I would like to have a date picker pop up when I open a new sheet and have the selected dates input to the script, but I haven't been able to figure it out yet. Any help would be greatly appreciated.
function main(){
var sheet = SpreadsheetApp.getActiveSheet();
sheet.clearContents();
var header = [["Calendar Address", "Calendar Name", "Event Title", "Event Location", "Event Start", "Event Description" ]]
var range = sheet.getRange(1,1,1,6);
range.setValues(header);
sheet.setFrozenRows(1);
// var mycals is an array of google calendar id's; for gsuite, this is the email address of the user which calendar you will be viewing.
var mycals = ['9ss30f8ktuvbedmemka1ve8jss#group.calendar.google.com','8nmutqctujaetrnt5kfvi56kuo#group.calendar.google.com','ae1d2v0sqtktc183546u6cenps#group.calendar.google.com','ilr8eqk2l0ua9pr50t5307ivq8#group.calendar.google.com','5qubvv7mj5vjf7h1hhc23515h8#group.calendar.google.com', 'p2a9plkjd3vv9c87kb5kirapqk#group.calendar.google.com', '9ubfnjrb83tiqgi5l1nitaodp0#group.calendar.google.com', 'l6ouqfpktn05hstmokj8jhr1s4#group.calendar.google.com' ]
for (var j=0;j<mycals.length;j++) {
var cal = CalendarApp.getCalendarById(mycals[j]);
// error handling in case you don't have access to any specified calendar
if (!cal) { continue; }
var events = cal.getEvents(new Date("12/30/2019 00:00:00 EST"), new Date("1/3/2020 23:59:59 EST"));
for (var i=0;i<events.length;i++) {
var row = sheet.getLastRow() + 1
var details=[[events[i].getOriginalCalendarId(),,events[i].getTitle(), events[i].getLocation(), events[i].getStartTime(), events[i].getDescription()]];
var range=sheet.getRange(row,1,1,6);
range.setValues(details);
sheet.getRange(i+2, 5).setNumberFormat("mm/dd/yyyy h:mm Am/PM");
}
sheet.sort(1);
}
var lr= sheet.getLastRow();
for(var k=0+1; k<lr+1;k++){

Answer 1

Assuming that the rest of your code works then try this modification:
function main(){
var sheet = SpreadsheetApp.getActiveSheet();
sheet.clearContents();
var header = [["Calendar Address", "Calendar Name", "Event Title", "Event Location", "Event Start", "Event Description" ]]
var range = sheet.getRange(1,1,1,6);
range.setValues(header);
sheet.setFrozenRows(1);
var mycals = ['9ss30f8ktuvbedmemka1ve8jss#group.calendar.google.com','8nmutqctujaetrnt5kfvi56kuo#group.calendar.google.com','ae1d2v0sqtktc183546u6cenps#group.calendar.google.com','ilr8eqk2l0ua9pr50t5307ivq8#group.calendar.google.com','5qubvv7mj5vjf7h1hhc23515h8#group.calendar.google.com', 'p2a9plkjd3vv9c87kb5kirapqk#group.calendar.google.com', '9ubfnjrb83tiqgi5l1nitaodp0#group.calendar.google.com', 'l6ouqfpktn05hstmokj8jhr1s4#group.calendar.google.com' ]
var today=new Date();//added
var day=today.getDay();//added
var start=new Date(today.getFullYear(),today.getMonth(),today.getDate()-day+8);//added
var end=new Date(today.getFullYear(),today.getMonth(),today.getDate()-day+12);//added
for (var j=0;j<mycals.length;j++) {
var cal = CalendarApp.getCalendarById(mycals[j]);
// error handling in case you don't have access to any specified calendar
if (!cal) { continue; }
var events = cal.getEvents(start,end);
It looked like you want to view next weeks events between monday and friday. If not then make it a bit clearer what you are looking for.
