Google Sheets deleteRow not working in my Macro - google-apps-script

Question

I'm trying to build a Macro to erase all the rows that have empty values on column D. Originally, I was using this code that I found:
function deleteRows() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var s = ss.getSheetByName('Datos Competidor 2 - EV');
var r = s.getRange('D:D');
var v = r.getValues();
for(var i=v.length-1;i>=0;i--)
if(v[0,i]=='')
s.deleteRow(i+1);
};
However the excessive number of calls to the API made this really slow and some times even fail due to a timeout.
I decided to just add all the rows that met the condition to a list and then just pass that to the deleteRow() in order to only call the API once using this code:
function deleteBlankRows() {
emptyRange=[]
var ss = SpreadsheetApp.getActiveSpreadsheet();
var s = ss.getSheetByName('Datos Competidor 2 - EV');
var r = s.getRange('D:D');
var v = r.getValues();
for(var i=v.length-1;i>=0;i--)
if(v[0,i]=='')
emptyRange.push((i)+":"+(i));
ss.getRangeList(emptyRange).activate();
ss.getActiveSheet().deleteRows(ss.getActiveRange().getRow(), ss.getActiveRange().getNumRows());
};
The execution seems to work just fine, completing in 1 to 2 seconds, however, rows aren't erased as much as selected by the end of the execution.
This is what I see:
Final result
Any ideas why this is happening?
Thanks!

Answer 1

I believe your goal is as follows.
You want to reduce the process cost of your script.
In this case, how about using Sheets API? When Sheets API is used, I thought that the process cost for deleting the rows can be reduced a little. When the Sheets API is reflected in your script, it becomes as follows.
Modified script:
Before you use this script, please enable Sheets API at Advanced Google services.
function deleteRows() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var s = ss.getSheetByName('Datos Competidor 2 - EV');
var values = s.getRange('D1:D' + s.getLastRow()).getDisplayValues();
var sheetId = s.getSheetId();
var requests = values.reduce((ar, [d], i) => {
if (!d) ar.push({ deleteDimension: { range: { sheetId, startIndex: i, endIndex: i + 1, dimension: "ROWS" } } });
return ar;
}, []).reverse();
Sheets.Spreadsheets.batchUpdate({ requests }, ss.getId());
}

Delete Rows with empties on column D
function deleteBlankRows() {
const ss = SpreadsheetApp.getActiveSpreadsheet();
const s = ss.getSheetByName('Datos Competidor 2 - EV');
const r = s.getRange('D1:D' + s.getLastRow());
const v = r.getValues().flat();
let d = 0;
v.forEach((e, i) => {
if (!e) {
s.deleteRow(i + 1 - d++)
}
})
}
