New Post: NPOI 2.1.1 is useless with XLSX file

Hello,

I am using latest NPOI to open and to save an XLSX file.

That XLSX file has a lot of sheets with tables and graphics. The test I made was only to open and immediately to save the file.

After that, I tried to open the Excel file and the file appeared corrupt. Excel has told me to fix it and I pressed OK. After I pressed OK, the file was fixed and all the sheets are present, however, graphics appeared bad formated.

Any help on this please?

Thanks in advance,
Jaime
