I've been working on a programing language to read and write Excel spreadsheets. Or more accurately I've been writing a custom programming language and porting my library to it, so I can transpile it out to other languages. Currently it is being transpiled to C++ and C# https://github.com/NumberDuck/NumberDuck-CPlusPlus https://github.com/NumberDuck/NumberDuck-CPlusPlus https://github.com/NumberDuck/NumberDuck-CSharp https://github.com/NumberDuck/NumberDuck-CSharp
