The Excel LAMBDA function has the following syntax and arguments: Earlier, recursion in Excel was only possible through VBA or Office Script. This feature is called 'recursion', and this is what makes LAMBDA so effective.

How is that possible? Due to the fact that a LAMBDA-defined function can call other functions or even itself as many times as needed. computationally universal) and allows users to perform almost any calculations in the native formula language. Microsoft announced LAMBDA in December 2020 proudly claiming that the new function makes Excel Turing-complete (i.e. At heart, it is a universal model of computation in which all functions are deemed anonymous and can be formed by abstraction. In computer science, the concept of lambdas dates back to lambda calculus (λ-calculus) introduced by American mathematician and logician Alonzo Church in the 1930s. The lambda symbol (λ) representing the 11th letter of the Greek alphabet is often used in physics, mathematics and computer science, where it carries different meanings. The LAMBDA function works without macros, VBA or JavaScript, so every user and not just programmers can benefit from it.

And then, instead of typing your original lengthy formula, you can refer to BestFunction() anywhere in your workbook. Simply put, you can now take any existing formula, whatever complex it is, wrap it up in LAMBDA, and give it any name you like, say BestFunction.

The LAMBDA function in Excel is designed to create custom functions that can be called by user-friendly names and reused throughout a workbook.
