Shall i restore deleted form submission?

Hi,

Can you please give us more details with your situation? This way, we will be able to provide advise based on what result you need to have

Please be informed that once form submission is deleted, there is no option on recovering it. You may try recovering the data by the options below:

1. Revision History Tool - You may use this tool and revert your form to a previous saved point. It will restore the previous submission data as well. But this does not cover submitted data after the last saved version of form.

2. Import Data application - Another way to regain the submission data is via the submission email. You can review the submission sent email of your form in your sent email history logs and then use our Import Data app to add them into the submissions panel again.
