Why Analysts Trust SheetSage
Most errors in financial models come from lookup failures and formula drift. SheetSage targets the root causes.
Detects missing FALSE arguments that cause approximate matching disasters. Also flags invalid column indices.
Finds lookup ranges like A1:B10 that lack $ anchors, preventing them from shifting when you copy formulas down.
Spot hardcoded thresholds (e.g., * 1.05) buried in formulas. Extract them to assumption cells for better maintainability.
Don't fix 5,000 rows one by one. SheetSage groups repeated formulas into a single "Cluster," letting you fix the pattern instantly.
Every fix creates a hidden snapshot. If a fix breaks your logic, hit "Restore" to revert instantly. Zero risk refactoring.
Built on Apps Script. Analysis happens within your Google session. No data, formulas, or cell values are sent to external servers.
Open Extensions > SheetSage. Click "Scan Workbook" to analyze every formula in seconds.
See your Health Score. Issues are ranked by risk and clustered by formula pattern.
Apply auto-fixes for VLOOKUPs or anchoring. Use guidance to refactor hardcoded values.
Enterprise-friendly by design: audit locally, keep control, and share only what you choose.

The complete Privacy Policy and Terms are available as standalone pages.
SheetSage (“we”, “us”) is a Google Sheets add-on that scans a workbook for risky formula patterns and provides safer fixes with rollback. For privacy questions, contact privacy@sheetsage.co.
This Privacy Policy applies to the SheetSage add-on, and our website/documentation. It does not govern Google’s handling of your data inside Google Workspace. Your use of Google Sheets, Drive, and Apps Script is subject to Google’s own terms and privacy policies.
In most enterprise deployments, you (or your organization) are the Data Controller for workbook content, and SheetSage acts as a Data Processor / Service Provider to provide the add-on’s functionality. If your procurement process requires it, we can provide a Data Processing Addendum (DPA) upon request.
To scan and fix issues, SheetSage may read workbook formulas and ranges and may write fixes you initiate. Processing happens inside your Google environment.
When you apply a fix, SheetSage creates a restorable snapshot in a hidden sheet (e.g., SheetSage_SNAPSHOT) so you can revert changes if needed. Snapshots live in the workbook, under your Google access controls.
SheetSage may maintain best-effort product metrics designed to stay local:
If you contact support, we’ll process what you send us (e.g., your email, message content, screenshots, logs, or sample formulas). We use it only to resolve your request and improve reliability.
SheetSage runs on Google Workspace and Apps Script infrastructure. Google is a core platform provider for the add-on. If we introduce additional subprocessors (e.g., for billing, support, or error monitoring), we will publish an up-to-date list and update this Policy as required.
We apply reasonable technical and organizational measures designed to protect the information we process (e.g., access controls for support systems). Workbooks and snapshots remain protected by your Google account and Workspace controls. No method of transmission or storage is 100% secure, but we work to maintain appropriate safeguards.
If support data is processed outside your country, we will take steps to apply appropriate safeguards where required (e.g., contractual protections).
Depending on your jurisdiction, you may have rights to access, correct, delete, or restrict processing of your personal information. To submit a request, contact privacy@sheetsage.co. We may need to verify your identity.
We may update this Policy from time to time. We will post the updated version and revise the effective date above. If changes are material, we will provide additional notice where required.
