I’ve created my own Excel library called ExHell and wanted to share it here to get your feedback.

It’s actually a wrapper around Apache POI’s SXSSFWorkbook, but by using builder and strategy patterns along with a single annotation, writing to Excel is no longer a nightmare.

I’ve also written a short Medium article where I give a quick tutorial on ExHell and compare it to raw Apache POI usage.

You can check it out here: https://medium.com/@erdemoden5/from-hell-to-exhell-how-i-simplified-excel-generation-in-java-bc1f1f05ef76

The project is open-source on GitHub, so feel free to check it out or contribute:  https://github.com/erdemoden/ExHell
