Caxlsx: Ruby gem for xlsx generation with charts, images, schema validation (github.com)

It looks like this is a community continuation of the axlsx gem which was maintained back in the day by Randy Morgan (randym) over at https://github.com/randym/axlsx. One of my earliest open source contributions was adding support so that you could output spreadsheets with "conditional" formatting (color something red if it is below some value, for instance). I remember Randy being extremely supportive of new contributors and it made me want to be a part of the ruby community.

Thanks for continuing the work!

Nice. Dropping this here for my fellow Excel and vim enjoyers

I use this library in production and love it!
