Excel does not provide a reliable audit trail of cell-level changes. Tracking what exactly changed in a spreadsheet can be difficult, especially when working with critical data.
What ExcelAudit Does
ExcelAudit records every cell change and creates a tamper-evident audit log. Each change is stored together with a cryptographic hash, making any manipulation detectable.
Typical Use Cases
- Internal audit of spreadsheets
- Tracking changes in financial files
- Spreadsheet data integrity verification
- Detecting unauthorized modifications
Baseline created after inserting the Excel file
Detected changes recorded in the audit log
Detection of audit log integrity violation
