Hi Jeffrey,
This appears to be a model consistency issue in the Excel Importer module's Column_NewEdit page, rather than an issue with the Excel import logic itself.
The error CE0456 – Condition for visibility needs to be updated indicates that the visibility configuration of a layout grid row needs to be migrated to the current Studio Pro format.
I found a similar issue reported in the Mendix Community involving the Excel Importer module and the same Column_NewEdit page.
I would recommend the following:
Column_NewEdit page in the ExcelImporter module.If Studio Pro does not allow you to update the condition, check whether the installed Excel Importer version is compatible with your Studio Pro version. Also check the module's dependencies and update any outdated widgets as required.
I would avoid changing the visibility condition to an arbitrary expression just to suppress the error, because that could change the importer's UI behavior.
A related discussion is available here:

If the error persists, please share your Studio Pro version and Excel Importer module version. That would help determine whether this is a module compatibility issue or a specific page-migration problem.
Hope this helps.
