What ideas do you think of whenever you hear the word formula? It refers to a string of words, a collection of mathematical processes, or an expression with the purpose of producing results as an output. The description of this "formula" and our VoltFormula are the same. VoltFormula is responsible for converting the formula used on other Formula Language platforms into the JavaScript programming language. This is essential for existing users of Notes and Excel1 who want to convert their existing formulas into the JavaScript language.

Two formula languages exposed as one implementation by VoltFormula

These two are wrapped into one parent formula language that encapsulates both implementations. We call this VoltFormula, aka RosettaJS. By nature of being a JavaScript exposed API library, the formula language can be extended via helper registration methods.


The aim of VoltFormula is to expose the capability to run certain functions of OpenFormula (Excel) and Formula Language (Notes @Function) in the context of Volt MX Go. This converts certain functions of OpenFormula and Formula Language into JavaScript. This JavaScript is used to build web-based applications. This is to help or to guide all the existing users of Formula Language and OpenFormula to transition into a web-based app. The VoltFormula reveals the JavaScript without any problem in converting the existing formulas in OpenSource and Formula Language.
