Export more than 50 Freeform submissions (without a lot of scrolling)
Sprout Reports is a flexible reporting plugin that allows you to create custom queries and export the results as CSV.

You could write a custom report using the default Twig Template or Custom Query reports building a report using Freeform variables in your Twig templates or a MySQL query that queries the report Freeform content table directly.

If you'd like to give your users settings, such as which Form to export submissions from, you can add settings to a custom Twig Template report or write a custom integration to define settings and handle your query using PHP.
