Hello Andreas Thank you for your suggestions.
I was on version 4.1.2 initially but i just changed to 5.0.0 and the issue remains the same. The files only have a size of 51 kb so I don’t know if that is what causes the problems. I will try to open the documents with other editors thank you for the tipp. Greets Simon On 05.11.21, 17:02, "Andreas Reichel" <[email protected]> wrote: Simon, please state which version of POI you are using. I have experiences similar challenges in the past, Pre 5.0.0 when writing large data > 4GByte zipped. No issue with 5.0.0 though (it has been fixed in this version). If you use only small files, then we could rule out this issue. Also, maybe try to open the file in LibreOffice and/or Gnumeric so we have a change to know, if your challenge is Excel specific. Good luck and best regards Andreas On Fri, 2021-11-05 at 15:47 +0000, Simon Baumeler wrote: > Hello > > I’ve encountered problems with apache poi: > > https://stackoverflow.com/q/69854351/9273200 > > Thank you in advance for any tips and tricks or suggestions on how to > fix this issue. > > Greetings > > Simon
