Question

I need to make Data Validation on a range of cells. I want a dropdown list, where the only option is the current date. To get the current date, I can use =TODAY(). The problem is, that the dates don’t remain static. When the sheet recalculates, so will all the dates. I need the dates to remain the same.

How can I work around this?

I found a blog where the answer might be, but I can’t see how the author has made his spreadsheet.

Answer 1

I will have a dropdown item which says “dags dato”. Next i use an eventlistener that checks if the text in a cell is changed to “dags dato”.

if so, it puts the current date in the cell, like this:

function onEdit(event)
{
  var ss = event.source.getActiveSheet();
  var r = event.source.getActiveRange();

  var currentValue = r.getValue();

  if(currentValue == "dags dato")
  {
    var dd = Utilities.formatDate(new Date(), "GMT", "yyyy-MM-dd");
    r.setValue(dd);
  }
}
