Audit Spreadsheet Formulas and Models in Google Sheets™

Review formula errors, hardcodes, inconsistent formulas, volatile functions, external dependencies and model differences with Sheet Analyst.

Quick answer

Sheet Analyst’s workbook audit scans spreadsheet formulas for common model-quality signals, including errors, hardcoded values, copied-formula inconsistencies, volatile functions, full-column references and external dependencies. It creates a review report so you can investigate potential issues rather than search a large workbook by hand.

What a workbook audit can surface

A workbook audit is a screening step. It highlights formula and structure patterns that may deserve review; it does not determine whether a model is financially or scientifically correct.

Workbook audit signals and why they may matter
SignalWhy review it
Formula errorsAn error may flow into downstream calculations or reports.
Potential hardcodesA constant inside a formula region may be intentional or may break consistency.
Copied-formula inconsistenciesA formula pattern that differs from neighboring formulas may indicate an accidental edit.
Volatile formulasSome functions recalculate frequently and can make a workbook slower or less predictable.
Full-column referencesUnbounded references can increase recalculation work in a large model.
External dependenciesImported or externally refreshed data can affect reliability and reproducibility.

Trace what feeds a result

Use formula tracing to inspect direct precedents (cells a formula reads) or dependents (formulas that refer to a selected cell). Tracing helps explain how an important output is built and where an unexpected value may be originating.

Compare ranges or model versions

When a model has changed, compare the relevant ranges to identify added, removed or changed values and formulas. Review the difference report in context: a flagged change is evidence to inspect, not a verdict that the change is wrong.

Review findings before changing the model

Run an audit on a copy or choose a result-sheet destination. Review each finding against the model owner’s documentation, confirm whether the pattern is intentional and record any follow-up outside the scan. Sheet Analyst keeps the workbook content in Google Sheets™ and does not transmit cell contents or formula results to Better Work Apps.

Common questions

Does a workbook audit certify that my model is correct?

No. It flags common formula and structure patterns for review. It cannot verify business logic, source-data validity or whether a model’s assumptions are appropriate.

Will an audit change formulas?

The audit workflow produces a report for review. Other tools may write outputs, so review the selected destination and confirmation before running any action that modifies a workbook.

Can I compare two model versions?

Yes. Sheet Analyst can compare ranges to help identify changed values and formulas. Select corresponding ranges and review the report in context.
