Send spreadsheets with confidence
Before you hand a workbook to a manager, client, or auditor, SheetBrain scans it and gives you a one-click review packet — a short summary of what it found and what you reviewed. The packet you share carries counts and status only: no formulas, values, or headers.
Free to install. Works with any Google account, including free Gmail.
A sample review packet
This is the whole thing — the exact text you copy and paste into your handoff after a workbook scan. No attachment, no link back into your sheet.
SheetBrain review packet (workbook scan) Readiness: Needs review Some flagged issues haven't been reviewed yet. Open each remaining item before relying on this workbook. Scan totals: 12 issues (8 errors, 4 warnings) Sheets skipped: 2 This session: - Reviewed: 5 - Fixes applied: 3 - Fixes undone: 1 - Notes added: 2 Re-check: 4 of 5 reviewed issues no longer present after re-check, 1 still needs review. Next steps: - Review 2 remaining errors - Review 1 remaining warning Privacy: this packet contains only counts and status — no formulas, cell values, column headers, sheet contents, or finding explanations.
That's the entire output. The reader sees how thorough the pass was — never what's inside the workbook.
What the packet never reveals
The packet you share is built from aggregate counts and approved status text only. By construction, sheet contents can't reach it.
No formulas
The packet never carries a formula or its pattern — only counts of what was flagged.
No cell values
Raw numbers, names, amounts, and dates are never read into the summary.
No headers or sheet contents
Column headers, sheet names, and tab structure are never included.
Counts and status only
Just totals, your review progress, and cautious next steps — no finding explanations.
The packet is a guidance handoff, not a clean bill of health. It reports what the scan checked and what you reviewed — it never certifies a workbook as correct.
How it works
Three steps, then a single click to copy the packet.
Scan your sheets
Open the SheetBrain sidebar and run Scan on each sheet. It flags broken references, mixed text and numbers, duplicate lookup keys, missing formulas, and visible errors — see exactly what Scan flags on the demo workbook.
Review and fix what's flagged
Work through each finding, apply the fixes you agree with, and mark the rest as reviewed. SheetBrain tracks your progress as you go.
Copy the review packet
One click builds the packet above and copies it to your clipboard. Paste it into an email, a Slack message, or a doc — and share the workbook with confidence.
See it on a real workbook
Copy the demo workbook with five planted issues, run Scan, and generate your first review packet in under two minutes.
