Team Forms allows you to perform bulk actions from the submissions screen, including deleting multiple responses at once.
To bulk delete submissions:
Open the submissions screen for the form you want to delete responses from.
Apply any filters (e.g. date range) as needed.
Tip: If you're deleting a large number of responses that span multiple pages, make sure to click the "Load more" button at the bottom of the screen to ensure all relevant submissions are visible. If you don’t, only the currently loaded responses will be affected.Select the responses you want to delete using the checkbox next to each row, or use the checkbox in the header row to select all visible responses.
Click the trash bin icon to delete the selected submissions. You’ll be asked to confirm the deletion before it proceeds.
