How to use

  1. Enter the formula for the first row.
  2. Choose the mode.
  3. Copy the formula and paste it into the top cell of a column.

How it works

  • Cell references like B2 become whole-column ranges like B2:B, wrapped in ARRAYFORMULA.
  • ARRAY-BLANK keeps empty rows empty.

Notes

  • ARRAY-HEADER shows a header in row 1 and fills the results below.
  • This is a Google Sheets function and does not work in Excel.

FAQ

Is what I enter sent anywhere?

No. Everything is processed inside the browser on your device.

Do I need to upload a file?

No. The formula is built only inside the browser.
