I have a google sheet linked to a Typeform. Data comes into the sheet when the type form is completed in the next blank row populating columns A-I.
When the data comes through I would like this to trigger some fairly standard formulas to be entered into columns K-N (4 columns).
How would I have these formulas added to specified columns when the sheet is updated?
You need to create a script with a Form submit trigger. This function will be called each time a form response is submitted. In that function you will execute the logic to populate your cells with the formulas you need.
