  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. Built in TypeScript, supported by the Handsontable Team.

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.

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