Since then, I have found a better, faster, and easier method, which works in . last non-empty rows most cases Find the Last Row & Column You can copy and paste one of the following functions as per your needs. is meant for a bound script, is very easy to implement, and works on the currently active worksheet. FindLastRowNColBoundScript(), should be used with an independent script. The given code is very simple. You can modify this function and pass variables such as ID and Worksheet names as parameters to make this function more dynamic. FindLastRowNColIndependentScript() /**
 * Function should be used for bound script.
 * Function use getDataRange().getValues() method to 
 * find lastRow and LastColumn of that Spreadhseet.
 */
function findLastRowNColBoundScript() {
  const sheet = SpreadsheetApp.getActiveSheet();

  const data = sheet.getDataRange().getValues();
  const lastRow = data.length;
  const lastCol = data[0].length;

  console.log(lastRow);
  console.log(lastCol);

  return [lastRow, lastCol];
}

/**
 * Function should be used for independent script.
 * Function use getDataRange().getValues() method to 
 * find lastRow and LastColumn of that Spreadhseet
 */
function findLastRowNColIndependentScript() {
  const ss = SpreadsheetApp.openById("<Your Spreadsheet's ID>");
  const sheet = ss.getSheetByName("<Name of the worksheet>");

  const data = sheet.getDataRange().getValues();
  const lastRow = data.length;
  const lastCol = data[0].length;

  console.log(lastRow);
  console.log(lastCol);

  return [lastRow, lastCol];
}
