Show HN: Excel Custom Functions in Zig

A Zig package for implementing Excel custom functions against the ancient C SDK.

This exists because I wanted to learn about Zig's C interop and comptime to see if it was possible to make the Excel C SDK slightly nicer to work with.

It's just a demo, I wouldn't use it for anything important, but I learnt a lot doing it. There is also a demo repo: https://github.com/AlexJReid/zigxll-standalone

Thank you! Yes they've been around a long while. They perform well and can make use of multiple threads etc. The SDK is pretty old school so best to use a layer on top such as xllify, Excel-DNA...
