Questions & Answers

Q: How does the script identify the current active cell in the spreadsheet?

The script uses the "getActiveCell()" function to retrieve the current active cell in the active sheet of the Google Sheets document.

Q: Can the script distinguish between different tabs in the Google Sheets document?

Yes, the script includes logic to check the name of the active sheet and compare it to a predefined list of tabs that the script should apply to. This allows the script to work only on specific tabs.

Q: What happens if a non-formula value is entered in the active cell?

The script includes a check to ensure that the active cell contains a formula. If the cell does not contain a formula, the script will not execute the drag-down functionality.

Q: How does the script update the dragged formulas when changes are made?

The script utilizes an "on edit" trigger, which is triggered whenever a change is made to a cell in the spreadsheet. By comparing the old value and the new value of the formula, the script determines if the formula needs to be updated and performs the necessary drag-down operation.
