About Donation

Since Github sponsorship is not supported in China so far, it's hard to get donation from Github channel. I'm strictly limiting my contribution time on NPOI these 2 years although it looks to be still maintained well. If you profits/benefits from NPOI and you believe it's useful, please donate this project. Thank you!

To Get Started with NPOI (on Windows 10)

1. Open PowerShell and run the following command:

git clone https://github.com/nissl-lab/npoi-examples

2. Open npoi-examples/ss/CalendarDemo/CalendarDemo.csproj with Visual Studio 2019 community version and click 'Run program' button
3. You will see a new generated file called Calendar.xls under npoi-examples/ss/CalendarDemo/bin/Debug folder
4. Open the Calendar.xls with Microsoft Excel or Kingsoft WPS
5. Go back to Powershell window and run the following command

cd npoi-examples/ss/CalendarDemo/bin/Debug
./CalendarDemo -xlsx 

6. You will see a new generated file called Calendar.xlsx under npoi-examples/ss/CalendarDemo/bin/Debug folder
7. Open the Calendar.xlsx with Microsoft Excel or Kingsoft WPS

Conclusion: The result of Calendar.xls and Calendar.xlsx looks same in Microsoft Excel or Kingsoft WPS but they are totally different file formats generated by NPOI.
