How to use it in your own spreadsheet

  2. Enter the formula in an empty cell, changing the references or literal values to match your sheet.
  3. Compare the output with a manual check on a small known example.
  4. Extend the formula to a larger dataset only after you understand the result.

Common problems and practical checks

  • Check unwanted spaces, character case, and whether the input is stored as text.
