Find the next thing to check.
Look up a question, inspect a formula’s structure, then try a working example.
Published explanations come from 19 original troubleshooting topics. The lookup inspects structure without calculating a pasted formula. For generated advice and an explicit local trial, use the local formula assistant. Current task observations remain available inside task and function worksheets.

Generate an English explanation with Chrome’s local model. Suggestions can be wrong; inspect the assumptions and run a separate trial on your sample. Opening this section does not generate or execute a formula.
Checking local model availability…
Unselected columns keep literal text, including leading zeros, = signs and error-looking labels. Selected numeric columns accept plain finite numbers; their empty cells are blank.
| Cell row | A | B | C |
|---|---|---|---|
| 1 | Region | Status | Amount |
| 2 | East | Paid | 10 |
| 3 | West | Paid | 20 |
| 4 | East | Pending | 30 |
| 5 | East | Paid | -5 |
The trial writes only to J2 in a copy of these literal cells. It allows at most 144 result cells and stops a calculation that exceeds its time limit. No model suggestion is run automatically.
Your question, cells and answer remain in this tab unless you download them. They are not put in the URL or browser storage. Model files may need a browser-managed download. No paid backend or prompt upload is configured.

Choose the helper’s output shape
SCAN, BYROW and MAP give a LAMBDA different inputs and expect different outputs.
- SCAN passes the previous state and current value to a two-parameter LAMBDA; its output contains the successive states.
- BYROW supplies one row at a time and expects one result for that row. Name parameters for what they receive, not for worksheet addresses.
- Check required arguments and scope, then test a reordered source or an empty row. Optional-parameter examples have their own documented browser limits.
