Form that sends data to an admin panel and can export it

there are 2 very popular form plugins

  1. Gravity Forms – extremely customisable and saves all data to your database (Commercial)
  2. Contact Form 7 – also saves everything to your database and easy to use (Free)

Both send the data to the Admin panel so you can review inside WordPress.

I know that Gravity Forms has an option to EXPORT the form entries as a CSV file.

Review Form Submissions without logging in
Both can send email notifications to your email address so you can see what has been submitted without logging into WordPress.

The other way to see all the form submissions without logging in is to open your SQL database and view the data there. Then you can save the table as a CSV.
