Exporting Data to Re-import: The Invalid Column Headings Issue

Often you’ll need to export data from CRM, make changes, and then re-import the data using CRM’s out-of-box capabilities. In doing this, you might receive the message “The data has invalid column headings, so you will not be able to re-import it” pop up. What is this message and how do I successfully export my data?

The issue actually has to do with duplicate display names. Since the export writes the display name as the column name, you cannot have duplicates because CRM doesn’t know how to match up the columns again when it re-imports the data.
In the scenario below, there is an issue with a duplicate status fields; the out-of-box status and a custom status field with the same name.

Hopefully this will help you get past this error message and successfully export your data for re-importing. Interested in taking your CRM experience to the next level?
