How can I Import Submissions?

You've opened a thread about "import submissions" but provided us with no details. So I am unsure of if I am understanding your issue right now other than you are trying to import submissions.

Are you migrating from formscentral? Or?

If you are coming from formscentral please see http://www.jotform.com/formscentral and also this guide here http://www.jotform.com/help/309-How-to-Migrate-Form-Data-from-Adobe-FormsCentral-to-JotForm.

Should that not be the case and you just want to import submission styled data then please see this App here http://apps.jotform.com/app/import_data.

If you meant something else then we ask that you please return to your thread here and let us know so that we can help you better.
