The BYCOL function in Microsoft Excel applies a LAMBDA function to each column in an array or range and returns one result per column. This can be useful for processing data in an array or range “by column.” For example, if BYCOL is given an array with 3 columns, it will return an array with 3 results. The calculation performed on each column is provided by a custom LAMBDA function.
