You or your team applies the corrections. Each issue comes with a specific suggested fix. **Who should order this?** Any business that makes decisions from spreadsheets: budgets, inventory, financial models, pricing sheets, project trackers. Especially if nobody has ever audited the sheet. Questions? Email support@sheetguard.io © 2026 SheetGuard. All rights reserved.
