In Microsoft Excel, the LAMBDA work is first used to make a generic equation. When a generic equation has been completed and tested, it is ported to the Name Manager, where it is formally defined and named.

One of the critical advantages of a custom LAMBDA function is that the logic contained in the recipe formula is only one spot. This implies there is only one copy of code to update when fixing issues or updating functionality, and changes will naturally proliferate to all occurrences of the LAMBDA function in the workbook.
