Hi Rebecca, > However, is there any reason not to actually update xlsxwriter?
I couldn't find one, so I've packaged 3.2.9: https://salsa.debian.org/python-team/packages/xlsxwriter/-/merge_requests/1 One side effect you should know about: upstream stopped shipping the built HTML manual, so the package loses its offline docs. I've written up the options in the MR. I also ran pandas' Excel tests against 3.1.9 and 3.2.9 in a sid container and got identical results, so nothing breaks for the pandas we ship today. But that's 2.3.3, so it doesn't tell us anything about 3.0. If you get a chance to build your pandas 3 against it, that would actually answer the question. Needs a sponsor still. I'll ask on debian-python. Malik
