Hello Ed,

While you could get the visible columns through the grid state, at this point there isn't a direct way to add such mapping, since there is only the index of the column. We made this feature request on your behalf for exposing the Field in the state too: https://feedback.telerik.com/blazor/1489571-add-field-property-in-grid-s-columnstate. That would help in this case, I think, and you can Follow it to get status updates via email. We've also added your Vote on your behalf to raise its priority.

In the meantime you could consider matching the indexes in the state with custom column descriptor collection, similarly to the approach from my post at the end of this page.

To also cover the case from your support ticket here for completeness - the need for this is likely to diminish (of not go away entirely) once export for all pages is implemented for OnRead: https://feedback.telerik.com/blazor/1469312-include-all-pages-in-excel-export-should-work-with-onread. I'm also attaching here the sample from the ticket that shows the general concept of getting the grid state and looping through it.

I have edited the opener post to add an example and some explanations that you can use as base for further development.
