There was a problem hiding this comment.
self.data used to be cleared in case of errors, now it is not anymore...
This is used in reports for example (maybe elsewhere too), which now report on previous data, even after trying to open something else and failing.

If the file was in incorrect format, the exception was sometimes thrown already by
FileFormat.get_reader. To see this, rename an arbitrary file to .xlsx and try to load it.The code would be simpler with a single try-except. However, since it catches any exception, I prefer wrapping a single call, hence two separate try-except blocks.
