How to save as a reusable Excel function

LAMBDA is a built-in Excel feature (Microsoft 365) that lets you create custom functions without VBA. The formula above works as-is when pasted into a cell.

To save a LAMBDA as a reusable named function:

  1. Go to Formulas → Name Manager → New
  2. Enter a name, e.g. PO.SF.CH.Liq.dP.SI
  3. In Refers to, paste the LAMBDA formula without the trailing invocation (...)
  4. Click OK

Now use =PO.SF.CH.Liq.dP.SI(...) anywhere in your workbook.
