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.

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.

Keep zeroes and missing observations distinct
A recorded zero contributes to a numeric mean; a blank does not represent a measured zero.
- Name the unit being averaged: records, groups or weighted amounts. An average of group averages need not equal the record-weighted result.
- Count numeric observations, including zeroes. Review text numbers before deciding whether to convert or exclude them.
- Test an all-empty group and a measured-zero group separately. Preserve record order and repeated labels when computing row means.
