this sheet to open the sheet linked to your form.
If you disconnect and later reconnect Google Sheets, new entries will go to a completely new sheet, not the original one.

Fillout has many powerful features like branching and conditional hide/appear logic. No matter how complex your needs are, there’s a way to build it in Fillout.
Working with different field/question types in Fillout
Date times- Note that all date timestamps that are sent to your Google Sheet (using the
Date time pickerfield in Fillout) are written in UTC. - To display times in a local timezone, you can add an extra formula column to do so.
- By default, each part of the address field is added to separate columns in your Google Sheet. This makes it easy to filter responses by city or state, or simply hide the columns you don’t need.
