In VBA for Excel, I can get the column of the cell making the call to a custom function like this:

ThisCol = Application.Caller.Column

What is the equivalent in Google Scripts?
I've been trying to find my way through the API docs, but coming up empty....

I call this function in a cell in each row of a range. The function sums contents of a range of cells across the row. Here's the VB:

Public Function SumDays(row As Integer)

  Dim credit As Double

  NumCols = Range("D8", Range("D8").End(xlToRight)).Columns.Count
  ThisRow = row
  ThisCol = Application.Caller.Column  ' column containing the cell calling the fn

  credit = 0

  For i = (ThisCol + 3) To NumCols
     'do stuff across the range of cols in ThisRow
     ' If Cells(ThisRow, i) = ....
  Next i

  SumDays = credit
End Function

The answer to your first question is:


function test() {
  return SpreadsheetApp.getActiveSheet().getActiveCell().getColumn(); 


enter image description here


Add the code under Tools>Script editor and press the save button.


I've prepared an example file for you: sample GAS code

  • Should this still work? If I run getColumn from within a cell it always returns 1, regardless of which cell. Mar 25, 2014 at 13:02

    @JacobJanTuinstra - It seams to be an issue with the New Google Spreadsheets. It's working when I check your example file, and if create a new file with the new features turned off. Still not my files created in New Google Spreadsheet. Mar 25, 2014 at 21:52

    This worked fine for me I have used it with SpreadsheetApp.getActiveSheet().getActiveCell().getValue()

    This is wrong answer, because when saved document starts again active cell is A1, when calling custom function can be anywhere else. Dec 30, 2017 at 15:24

    This code gets the active cell (i.e. the user selected cell) - it does not answer the question "how do I get the column of the cell making a call to a custom function?".
