This extension facilitates uploading CSVs via the CiviCRM import interface. Useful for bulk uploading events or campaigns etc.
The civicrm api entity can be set to, for example, Event or Campaign. (Note that for entities like Contribution Pages you need to use API names - either ContributionPage or contribution_page). The same permissions apply as for any api create call.
To use you need to go to civicrm/csvimporter/import . More notes are in the README.
