Export Excel Based on NPOI and NPOI

Export Excel Based on NPOI and NPOI

 
In the previous article [query and export of big data], I mentioned how to use the NPOI component to export an Excel file. I wanted to share it with you last time, but I was very busy recently. Today I took the time to sort it out, share it.
 

Based on the above analysis, we will briefly draw a UML diagram of this function to facilitate understanding.

With the above analysis, the implementation seems to be a matter of course.

Conclusion:

Where does the excel file exported by npoi exist? Is excel stored on the server?

Standard excel format, not webpage format

Net export EXCEL using NPOI, if the corresponding statistical chart is automatically generated

Use the function in the EXCEL template to write the display area! After the Excel file is generated, it will be displayed in statistics!
