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:
- Go to Formulas → Name Manager → New
- Enter a name, e.g.
PO.ESP.Cable.Resistance.SI - In Refers to, paste the LAMBDA formula without the trailing invocation
(...) - Click OK
Now use =PO.ESP.Cable.Resistance.SI(...) anywhere in your workbook.
