Based on ewbi's go calc excel formula parser http://ewbi.blogs.com/develops/popular/excelformulaparsing.html. This library contains methods to beautify an excel formula. This library also contains functions to convert an excel formula to JavaScript (ECMAScript) or C# and python.
Hey @jr-grenoble @cmargoli I'm the co-founder of Voltade.com, which converts Excel formulas into APIs in a few clicks. Thought this might be relevant to you too!
It would be useful to have this functionality as a VS Code extension or language.
