Excel Formula Language

[DecimalTurn]

Language name

The Excel Formula Language is likely the most popular programming language and with the introduction of LAMBDA, it's even turing complete.

Since fomulas live inside of Excel they are rarely seen as source code, however there are instances of people sharing formulas/lambdas on GitHub, so adding support for it on GitHub could be considered.
