The add-on is designed to ease the process of creating Google Sheets IF formulas of any complexity. With it, you don't need to think about the correct syntax anymore. All you need to do is enter your records and choose operators for your conditions from the predefined lists.
The tool can also display existing Google Sheets IF statements in pieces: separate conditions from the results and comparison operators from your records. This way, you will edit and save formulas even quicker.
