    Good morning/evening

    Given a data structure passed via setDataSource (ref.

    I would like to remove the auto generation of the column name and keep the default A, B, C ... as I would like to have a good reference whenever a formula is applied/inspected

    I created a dataSource array with the first object the list of the column headers and frozen the first generated row to have the name reference but I really need to default the spreadsheet column titles to A,B,C

    Any idea on how to do that?

    Hi Davide,

    You may use the setValue() method to set the headers back to letters. Please refer to the following code snippet and the sample demonstrating the same:
    sheet.setValue(0, colIndex, colLetter, GC.Spread.Sheets.SheetArea.colHeader);

    Thanks for the reply, I've tried to replicate your example from codesandbox and I get an error evaluating the formula.


    '=SUBSTITUTE(ADDRESS(1,' + colIndex + ',4),"0","")',

    returns an error: {_error: "#NAME?", _code: 29} so the column header gets populated by #NAME?

    Apologies, I found the error I was making, I basically removed the sheet argument from your snippets as I'm referring to the window object.

    This solved my problem, thanks so much
