3. hyperformula

   2 4 2,331 7.0 TypeScript

   HyperFormula is an open-source headless spreadsheet for business web apps. It comes with over 400 formulas, CRUD operations, undo-redo, clipboard support, and sorting.

   

   My initial thoughts were how does a spreadsheet do it? but it's a different kind of beast.

   In search of a parser toolkit I had come across this https://github.com/handsontable/hyperformula which uses chevrotain to parse spreadsheet formulas and decided to use chevrotain for the parsing.

   NoteCalc is a handy calculator trying to bring the advantages of Soulver to the web.

   

   I made a list of calculators like this which were shared here on HN over time https://gist.github.com/SMUsamaShah/6546011091d53380354484a3...

   From these https://bbodi.github.io/notecalc3/ and https://notepadcalculator.com/ are the most programmer friendly (supporting <<, ^, binary, hex etc)
