How to retrieve data from deleted fields?

Please be noted that deleting the form fields from the form will also remove the submission data of the field from the submissions view. However, this data can be retrieved only by reverting the form to the last working version. Once you get the backup of these submissions, you may again revert to the recent version as well.

If you collected any data using your new form fields, then those data will be removed from the submission page once you revert your form to the previous version, so I would suggest you download your data for backup purpose before reverting your form to a previous version.

If you want to keep the data from the old fields, you should hide them instead of deleting them.
