Hi,
I am trying to convert an excel file from .XLS to .XLSX with the code below.
Workbook wb = new Workbook(file);
wb.Save("new_format_file.xlsx", SaveFormat.Xlsx);
It can covert 10,000+ files, except for one file in the attachment below.
aa.zip (308.3 KB)
Could you tell me how to fix or the limitation for converting file?
Best Regards,
Chokchai L,
