The formula
"Use LET to assign names to intermediate calculation results inside a formula, making complex formulas readable and faster"
=LET(x, A1 + A2, y, A3 * A4, x + y)The LET function assigns names to calculation results, enabling easier management of complex formulas.
Step-by-step breakdown
- Define the first name (x) and its value (A1 + A2).
- Define the second name (y) and its value (A3 * A4).
- Use the defined names in a final calculation (x + y).
- This structure improves readability and performance.
Edge cases & warnings
- Using LET with circular references can lead to errors.
- If the defined names are not used in the final calculation, they will not affect the result.
- Exceeding the maximum number of names allowed in LET will cause an error.
Examples
"A1=5, A2=10, A3=2, A4=3"
25"A1=1, A2=2, A3=3, A4=4"
