AXLSX
xlsx generation with charts, images, automated column width, customizable styles and full schema validation. Axlsx excels at helping you generate beautiful Office Open XML Spreadsheet documents without having to understand the entire ECMA specification. Check out the README for some examples of how easy it is. Best of all, you can validate your xlsx file before serialization so you know for sure that anything generated is going to load on your client's machine.
Project mention: Caxlsx: Ruby gem for xlsx generation with charts, images, schema validation | news.ycombinator.com | 2026-03-06It 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!
