This module provides a token approach to list WebformSubmission fields in views.
It is used to optimize the page load and performance in case you are using a large database with submissions and you want to list lots of submission fields.

When you have a large amount of submissions and you want to list several fields in view, this could kill your server.
There are a lot of JOINS created with the same webform_submission_data table.

You can use this module to display unlimited number of fields in a view, without creating a new JOIN in the backend.
