Hi @rovisal, the functionality to write arbitrary data into a sheet with no existing headers is unfortunately no longer available in the Google Sheets node since its last overhaul in an attempt to simplify it. I too miss it 
But perhaps you want to check out this workflow instead? In this example I am writing a value in a random cell. You could adjust this workflow slightly to first create an empty spreadsheet (this should still work with the current Google Sheets node), then write in A1 (or wherever you need your header) after creating a new spreadsheet.
