Script to automatically insert a specific text in cells of a Google spreadsheet, based on a date in another cell, on the same row

Question

I have the following script provided by @ZektorH in another question of mine.

function onEdit(e) {
  if (e.range.getColumn() ==2) {
    //User edited the date co

I've reworked your code a bit, basically adding a condition to check whether the value in each cell equals "ENDED", and only deleting data if that's the case:

// Delete all "ENDED" values:
var resetRange = sheets.getRange(e.range.getRow(), e.range.getColumn() + 1, 1, sheets.getMaxColumns() - e.range.getColumn());
var resetValues = resetRange.getValues()[0];
for(var i = 0; i < resetValues.length; i++) {
  if(resetValues[i] == "ENDED") {
    var resetCell = sheets.getRange(e.range.getRow(), e.range.getColumn() + 1 + i);
    resetCell.clearContent();
  }
}

And also this, which deletes corresponding "ENDED" values if you edit to a later date:

// Clear past dates if new date is later:
var beforeDate = sheets.getRange(rowNum, colOffset, 1, foundCol);
var beforeValues = beforeDate.getValues()[0];
for(var i = 0; i < beforeValues.length; i++) {
  if(beforeValues[i] == "ENDED") {
    sheets.getRange(rowNum, colOffset + i).clearContent();
  }  
}

So, full code would be like this:

function onEdit(e) {
  if (e.range.getColumn() == 2) {
    //User edited the date column
    if (typeof e.range.getValue() === typeof new Date()) {
      //Value of edit was a date
      endColumns(e.range.getRow(), e.range.getValue());
    } else if (e.range.getValue() === ""  || e.range.getValue() === null) {
      var sheets = SpreadsheetApp.getActiveSheet();
      // Delete all "ENDED" values:
      var resetRange = sheets.getRange(e.range.getRow(), e.range.getColumn() + 1, 1, sheets.getMaxColumns() - e.range.getColumn());
      var resetValues = resetRange.getValues()[0];
      for(var i = 0; i < resetValues.length; i++) {
        if(resetValues[i] == "ENDED") {
          var resetCell = sheets.getRange(e.range.getRow(), e.range.getColumn() + 1 + i);
          resetCell.clearContent();
        }
      }      
    }
  }
}

function endColumns(rowNum, limitDate) {
  var sheets = SpreadsheetApp.getActiveSheet();

  var colOffset = 3; //Offset to account for your row Headers
  var dateHeader = sheets.getRange(1, colOffset, 1, sheets.getMaxColumns() - colOffset);

  var availableDates = dateHeader.getValues()[0];

  var foundCol = 0;
  for (var i = 0; i < availableDates.length; i++) {
    if (availableDates[i] >= limitDate) {
      break;
    }
    foundCol++;
  }

  var rewriteCells = sheets.getRange(rowNum, foundCol + colOffset, 1, sheets.getMaxColumns() - (foundCol + colOffset - 1));

  //Add your formatting and text below:
  rewriteCells.setValue("ENDED");

  // Clear past dates if new date is later:
  var beforeDate = sheets.getRange(rowNum, colOffset, 1, foundCol);
  var beforeValues = beforeDate.getValues()[0];
  for(var i = 0; i < beforeValues.length; i++) {
    if(beforeValues[i] == "ENDED") {
      sheets.getRange(rowNum, colOffset + i).clearContent();
    }  
  }


  // Clear all cells that are "white" (no header)
  for (var i = 0; i < availableDates.length; i++) {
    if (availableDates[i] === "" || availableDates[i] === null) {
      sheets.getRange(rowNum, colOffset+i).clear();
    }
  }
}

I hope this is of any help to you.
