LET
A hard formula for making complex calculations easier to read and reuse.
Syntax
=LET(...)Step-by-step explanation
- 1Use the formula to name reusable parts of your calculation.
- 2Build the logic in small pieces so the calculation is easier to follow.
- 3Confirm that the final result is easier to read and maintain than a nested formula.
Common mistakes
Using too many moving parts at once
Skipping small test cases
Forgetting that reusable names must stay consistent
