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 > > > Simon Baumeler | Informatiker Applikationsentwickler EFZ | Software > Engineer > id:5BC4E55C-070F-4D42-8D1C-BBD4BE51B72C > > FORMS YOUR DIGITAL PROCESS > ajila ag | Centralstrasse 8b | CH-6210 Sursee > T +41 41 555 52 49 | M +41 76 417 04 34 > [email protected] | www.ajila.com >
