How can I export the form submissions / data from Sitefinity?
To manage the responses to a form, on the Forms page, click the green count button in the Responses column of the respective form. The count button becomes clickable when the form responses number is higher than 0.
Click the number to see the list of form submissions.
You can export a selection of form responses by selecting the checkbox next to the form responses you want to export and then Select All.
Click the Bulk Actions button and choose Export to Excel option. The export function will export all form submissions ever submitted on the form. If you have exported data from a form before, that data will be in every file you export.
