Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.
The file you are trying to open, 'foo.xls', is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?
Clicking "yes" opens the file in Microsoft Excel 2010. I disabled "Protected View" modes in excel, but the error persisted.

metzlerd CreditAttribution: metzlerd commentedI'm afraid after much research, there is no way around this issue. There are no supported extensions that will support this, save perhaps changing doc type bo .xml, but this would still require custom client information. Closing this since there doesn't seem to be any way to code this. .
