Finding and Deleting All Emojis in a Google Spreadsheet - google-apps-script

Question

I have a Google Spreadsheet with thousands of cells with each cell being populated with strings with many different emojis.
Example of entries:
"Lol 😊","Haha 😊","Fire 🔥","👏👏👏Awesome!","Nice👍 See you tomorrow!😀",
"こんにちは😊", "你好😀"
But I want to delete all of the emojis, is there a search function I can run/piece of Spreadsheet code I can run to make the document devoid of emojis?

Answer 1

Cleaning Up with Regular Expressions
I don't have the time to do the whole thing but this will give you a start. I cleaned everything in one cell with this.
var sht = SpreadsheetApp.getActiveSheet();
var text = sht.getActiveCell().getValue();
var cleantext = text.replace(/[^\s\w]/g,'');//replace everything that's not whitespace or word characters with null
sht.getActiveCell().setValue(cleantext);
I used the line you provided as test data. Admittedly it needs a little tweaking because it's getting rid of some punctuation.
This is a little better.
function test()
{
var sht = SpreadsheetApp.getActiveSheet();
var text = sht.getActiveCell().getValue();
var cleantext = text.replace(/[^\s\w"!,]/g,'');//added "!,
sht.getActiveCell().setValue(cleantext);
}
So as you run it you may want to add a few more characters to don't replace list. That's it.
I have an expense report that I use to collect my expenses in different categories and I like to produce pie charts to help me get a big picture view of where my money is going. I use this Array Formula to help me gather the information into useful categories for me.
=ArrayFormula(IF(Row(C:C)=1,"Title",IF(LEN(C:C),IF(REGEXMATCH(C:C,"(?i)(string1|string2|string3|string4)"),D:D,""),)))
The regular expression provides an or function for adding additional matching for unexpected item appearing on my expense lists that I want to gather into these categories. If you need another matching term you just go into that formula and add another term as shown below
(string1|string2|string3|string4||string5)
The strings are replaced with real terms with no quotes unless they have quotes around them in the search target.

Here is some code that goes through one column of data and removes emojis from each cell.
You must replace Your Sheet Tab Name with the sheet tab name that the code should work on. This code currently only processes one column of data. The entire column of values is written back to the sheet in one write operation. Any character codes that are 5 characters or more are assumed to be emojis.
Test it on a few rows of data first.
function killEmojies() {
var arrayThisRow,columnOfValues,columnToRemoveEmojiesFrom,firstTwoChar,
i,innerArray,j,L,newCellContent,outerArray,
ss,sh,
targetSheet,thisCell,thisCellChar,thisCellVal,thisCharCode,thisCharCodeLength;
columnToRemoveEmojiesFrom = 1;
outerArray = [];
ss = SpreadsheetApp.getActiveSpreadsheet()
sh = ss.getSheetByName("Your Sheet Tab Name Here");
targetSheet = ss.getSheetByName("Your Sheet Tab Name Here");
columnOfValues = sh.getRange(1, columnToRemoveEmojiesFrom,sh.getLastRow(),1).getValues();
L = columnOfValues.length;
Logger.log('L: ' + L);
for (i=0;i<L;i++) {
thisCell = columnOfValues[i];//Get inner array
thisCellVal = thisCell[0];//Get first element of inner array
Logger.log(thisCellVal)
Logger.log('typeof thisCellVal: ' + typeof thisCellVal)
newCellContent = "";//Reset for every cell
innerArray = [];//Reset for every row loop
if (typeof thisCellVal !== 'string') {//This spreadsheet cell contains something
//other than text
innerArray.push(thisCellVal);
} else {
for (j=0;j<thisCellVal.length;j++) {//Loop through every character in the cell
thisCellChar = thisCellVal[j];
thisCharCode = thisCellChar.charCodeAt(0);//Character code of this character
thisCharCodeLength = thisCharCode.toString().length;
Logger.log('typeof thisCharCodeLength: ' + typeof thisCharCodeLength);
Logger.log('this val: ' + thisCharCode);
Logger.log('thisCharCodeLength: ' + thisCharCodeLength);
Logger.log(thisCharCodeLength < 5);
if (thisCharCodeLength === 5) {
firstTwoChar = thisCharCode.toString().slice(0,2);
Logger.log('firstTwoChar: ' + firstTwoChar)
}
if (thisCharCodeLength > 4 && (firstTwoChar === "54" || firstTwoChar === "55" || firstTwoChar === "56")) {
continue;//exclude character codes that are 5 or more characters long
//and start with 54 or 55
}
newCellContent = newCellContent + thisCellChar;
}
innerArray.push(newCellContent);
}
outerArray.push(innerArray);
}
targetSheet.getRange(1, columnToRemoveEmojiesFrom,outerArray.length,1).setValues(outerArray);
}

Replace emojis from text
I've found, you may use a REGEXREPLACE for that.
To replace all emojis from [A1] please try:
=REGEXREPLACE($A$1,"[🏻🏼🏽🏾🏿©®‼⁉™ℹ↔-↙↩-↪⌚-⌛⌨⏏⏩-⏳⏸-⏺Ⓜ▪-▫▶◀◻-◾☀-☄☎☑☔-☕☘☝☠☢-☣☦☪☮-☯☸-☺♀♂♈-♓♟-♠♣♥-♦♨♻♾-♿⚒-⚗⚙⚛-⚜⚠-⚡⚧⚪-⚫⚰-⚱⚽-⚾⛄-⛅⛈⛎-⛏⛑⛓-⛔⛩-⛪⛰-⛵⛷-⛺⛽✂✅✈-✍✏✒✔✖✝✡✨✳-✴❄❇❌❎❓-❕❗❣-❤➕-➗➡➰➿⤴-⤵⬅-⬇⬛-⬜⭐⭕〰〽㊗㊙🀄🃏🅰-🅱🅾-🅿🆎🆑-🆚🈁-🈂🈚🈯🈲-🈺🉐-🉑🌀-🌡🌤-🎓🎖-🎗🎙-🎛🎞-🏰🏳-🏵🏷-🏺🐀-📽📿-🔽🕉-🕎🕐-🕧🕯-🕰🕳-🕺🖇🖊-🖍🖐🖕-🖖🖤-🖥🖨🖱-🖲🖼🗂-🗄🗑-🗓🗜-🗞🗡🗣🗨🗯🗳🗺-🙏🚀-🛅🛋-🛒🛕-🛗🛝-🛥🛩🛫-🛬🛰🛳-🛼🟠-🟫🟰🤌-🤺🤼-🥅🥇-🧿🩰-🩴🩸-🩼🪀-🪆🪐-🪬🪰-🪺🫀-🫅🫐-🫙🫠-🫧🫰-🫶🇦-🇿#️⃣*️⃣0️⃣1️⃣2️⃣3️⃣4️⃣5️⃣6️⃣7️⃣8️⃣9️⃣]","")
I believe this regex will find all current emojis from your text.
Notes:
some emojis are compound for instance, an astronaut is 🧑🏼‍🚀. Regex needs to find only solid chars, so all compound emojis will be included.
I've tried to shorten the solution, and used actual emojis in RegEx. You may also see more "computer-like" solutions: [\u1F60-\u1F64]|[\u2702-\u27B0].... Those solutions use codes of emojis instead.
Another interesting option is given here. Remove all not printable chars: =REGEXREPLACE(A1,"[[:print:]]","")
skins are included:

Assuming all your text strings are single words followed by a space and then an Emoji, you can use the formula
=LEFT(A1,(FIND(" ",A1,1)-1))
This will return the textual contents of a cell only (A1 in this example).
If all your data is in a single column, you can just pull down and this will apply to all your data.
