@cmcaine , a few of these assertions I put because I couldn't find an instance or scenario where MS Excel generates this kind of tags.
How this excel file is created? Which software is used to create the file?
Maybe the performance issue is related to inlineStr. But can you give details on the size of the file, and how much time it takes to load on MS Excel and ExcelReaders.jl?
The file is generated by EXWA https://www.elcomsoft.co.uk/exwa.html
Really they should just generate a csv, but whatever.
ExcelReaders takes about 1m per sheet, which makes it about twice as fast.
Libreoffice loads it in 26s:
$ time libreoffice confidential.xlsx
libreoffice 26.10s user 2.65s system 121% cpu 23.716 total
Don't have access to MS Excel.
@cmcaine I see. Is it possible to generate a file with random data with EXWA that triggers this issue?
Not easily :(
I'd have to make a database with the same schema as WhatsApp uses, then use EXWA to export that as an xlsx.
I might be able to do this, but no guarantee I'll have the time or ability.

Here's an example excel file with inline strings, not generated by EXWA, though. Maybe helpful?

@cmcaine , yes I can work with that. Thanks!

I can't access the data of most cells because they are "inlineStr"
Can't share the sheet because it's confidential and resaving a non-confidential example in the software I have available encodes it differently.
