The error message is kind of buried, but if you look carefully, you’ll see: `Excel xlsx file; not supported`. This seems to just be a limitation of the python library you’re using: [python - xlrd.biffh.XLRDError: Excel xlsx file; not supported - Stack Overflow](https://stackoverflow.com/a/65266270)
