Looks good! Please attach some screenshots presenting the change and error message.

Does the hub support file uploads of those types?

What issue or ticket is this PR fixing? Is it #2112?

The hub currently only supports CSV files, so I handle the file format conversion in the UI. Now, supported file types (like Excel and OpenDocument) are converted to CSV in the UI before being uploaded to the server. This approach avoids needing to add additional format support on the server.

The issue related is: konveyor/enhancements#121
Regarding issue #2112 - we could not reproduce it.

IMHO we should search for an approach that doesn't require parsing and in-browser conversion to CSV or look for a different library.
The xlsx lib is a heavy one (claimed unpacked size of 7.5 MB) and has confusing browser/os support matrix (https://www.npmjs.com/package/xlsx)
