Hi RisingSun,
just to be sure: You are exporting from articy:draft using our JSON (Not unity) export with localization enabled. Is the error part in our export or after you tried to use the generated excel inside your C# code?
What are you using to read the excel files?
Has something changed in the last few updates regarding exporting localisation excel sheets?
Yes, some cells where automatically changed when ClosedXML tried to interpret text as a different type, for example a Date could be stored as a string, causing problems when you expected the string not a formatted date string. That was changed to always store any string as an actual string, without any built in conversion.That should be the only big change if i'm not mistaken.
The error you are mentioning sounds like a problem in the zip reading part of the excel.
Depending on the answer to my first question: What are you using to read the excels and/or can you send me one of those affected excel files to nico.probst(at)nevigo.com, so i can have a look.
Best regards
Nico
