Results remain in your form until you delete them. You can delete old results to make room for new results.
Important: Deleting results is permanent. There's no way to undelete or restore deleted results.
Delete Many Results
To delete your form's results, go to your form's "Results -> Delete Results" page.
You can optionally set a date range or a Results Filter to delete only results matching a criteria.
Delete Individual Results
To delete individual results, go to your form's "Results" page. Find the row for the result you want to delete and click the checkbox near the left of the row to select it. Then, click the "Delete" button above the table.
