Simple .ods file fails to load

[hayashi-stl]

I tried to use the latest version of svgtiler with even a simple .ods tilemap and it gave this error:

$ svgtiler a.txt a.ods
* a.txt
* a.ods

a.txt (just maps a to a square):
a.txt
a.ods (consists of a single a):
a.ods

Note that if I export that spreadsheet as a .csv or an .xlsx instead, svgtiler works.

Thanks for the report! Seems to be an upstream issue, so I've raised https://git.sheetjs.com/sheetjs/sheetjs/issues/3162

We could work around it, but then we wouldn't be able to tell which sheets are hidden.

[hayashi-stl]

Well, as it is, the documentation is inaccurate, since it claims to support .ods

[email protected] implements a workaround so that .ods files at least work, but hidden sheets will be treated as unhidden, until the upstream issue can be addressed.
