Dotnetcore NPOI Review By File Comparsion

This document is based on NPOI 2.2.0 tag and Dotnetcore/NPOI latest code

Files Count	Comparison Result
1408	Text files are identical
130	<5 changes
14	5-10 changes
13	>10 changes
6	only exists in dotnetcore/NPOI excludes csproj and unnecessary files

According to my code review, <5 changes are almost about formatting, comments and invalid code change, which can be ignored.

Even if the changes are bigger than 5, some of the code are still directly copied from some late version of NPOI.

The valid changes from dotnetcore/NPOI are very rare. I don't think it will be more than 2000 lines of code.
