## Summary

The author describes how the LET function in Google Sheets can be used to store values, strings and even URLs inside a single formula. By assigning the result of an IMPORTRANGE call to a variable, the same external data is fetched only once, reducing processing load. Additional string variables such as memo1 or memo2 act as human‑readable comments, because they are ignored by the calculation.

Beyond simple notes, the author stores a link to the generative‑AI conversation that helped create the formula in a variable called memo0. When the formula is later inspected, clicking the URL jumps straight to the original AI thread, preserving the rationale, discarded ideas and any follow‑up discussion. This technique turns the formula itself into a lightweight documentation layer, useful for anyone who maintains complex spreadsheets over months or years.

The piece also advises that users can ask generative AI for function suggestions, efficiency checks, or readability improvements, then capture the AI’s guidance directly in the sheet. Embedding the dialogue makes future edits faster and keeps the context of decisions close at hand.

## Key points

- LET lets you assign the IMPORTRANGE result to a variable, avoiding repeated fetches.
- String variables (memo1, memo2) inside LET serve as human‑readable comments.
- A URL to the AI consultation thread can be stored in a LET variable for easy reference.

## Why it matters

Embedding documentation and AI discussion links directly in Google Sheets formulas improves maintainability and efficiency for marketers and small businesses that rely on complex spreadsheets.
