Google Sheet speedup Loops - google-apps-script

Question

I have around 5000 rows. Now I want to move data for one sheet to another if their status is Delivered.
This is what I am doing:
function move(){
var activeSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet2");
var sourceSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1");
var lastSourceRow = sourceSheet.getLastRow();
var lastSourceCol = sourceSheet.getLastColumn();
var sourceRange = sourceSheet.getRange(1, 1, lastSourceRow, lastSourceCol);
var sourceData = sourceRange.getValues();
var activeRow = 0;
//Loop through every retrieved row from the Source
for (row = lastSourceRow; row > 1; row--) {
//IF Column B in this row has 'deal', then work on it.
if (sourceData[row-1][1] === 'Delivered') {
//then push that into the variables which holds all the new values to be returned
activeSheet.appendRow(sourceData[row-1]);
//delete current
sourceSheet.deleteRow(row);
}
Logger.log(row);
}
}
My problems:
Script is so slow it takes so much time to execute.
As per google policy script timeout in 5 mins.
So the loop has to be started again. So also index is set to null. So I can't check the record at the top if they are delivered or not.
Please can anyone provide me a better solution for this? I search for a faster loop but still no luck.

Answer 1

function move(){
const ash=SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet2");
const ssh=SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1");
var data=ssh.getDataRange().getValues();
var d=0;
var oA=[];
data.forEach(function(r,i){
if(r[1]=="Delivered") {
oA.push(r);
ssh.deleteRow(i+1-d++);
}
});
ash.getRange(ash.getLastRow()+1,1,oA.length,oA[0].length).setValues(oA);
}
The deletion of the rows always takes time. You could splice them out of the data array and clear the sheet and place them back in with a setvalues(). But if you have formulas this may mess some things up. I'll leave that up to you.
