Advanced Contact form 7 DB saves all Contact Form 7 submissions to the WordPress database with multiple features that you can use readily after installing and activating it.
One of the most robust features of this plugin is its multisite compatibility as it stores data for each site individually. You can filter the data using the date range to search specific date entries. Further, you can also set up filters to exclude certain forms entry on the database.
This plugin also lets you enable or disable the columns that you want to display on your database.
You can also export the data in different formats like CSV, Excel, and PDF. The plugin also provides an easy to set up import functionality.
