# Publisher Support If you're using DataGrab and Publisher, you will also need this extension: There is a known issue when using DataGrab to import Grid data when also using Publisher and using the matching/unique value in the Grid field config to try to update an existing Grid row. Your best option at this time is to delete all the Grid rows and have DataGrab re-create them all. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
