Understand and extend an inherited spreadsheet
Decode a complex spreadsheet you didn't build — then safely add new functionality.
Claude reads the workbook, maps how tabs and formulas connect, explains the logic in plain English, and proposes safe extensions — so you don't reverse-engineer someone else's model by hand.
Single model call (rung 2 of 6). Generate, extract, summarize, classify or translate. One request, one answer.
Not an agent: the sequence of steps is fixed in advance, so the whole path can be tested end to end.

Illustrative demoAn analyst inherits the budget model when its author leaves — and owns it Monday. Edit the inputs to tailor the output — it's baked synthetic data, so nothing leaves your browser until you run it live.
- Explain how this workbook flows: which tabs feed which, and what each key formula does.
- I want to add a scenario toggle — show me where to put it without breaking the existing logic.
