In December 2020, when the Lambda function was released for Excel 365 and Excel on the web, many people saw it as a weak attempt to replicate the Visual Basic for Applications (VBA) user-defined functions and pointed out some limitations it has. Limitations such as it needs to be put in a named range to be able to call it like a proper function. But Microsoft was just getting started then and the Lambda function is just one of many functions it released to empower users to create truly powerful custom functions.

LAMBDA
BYCOL
BYROW
