File Structure & Health Audit

Perform a Deep Diagnostic Scan of Your Spreadsheet

When an Excel file is slow, crashing, or returning weird values, diagnosing the root cause manually is like looking for a needle in a haystack. The File Health Audit tool acts as a diagnostic X-ray for your workbook. How it works: It scans the entire XML architecture of your file, bypassing the visual data. It generates an executive report detailing exactly how many broken formulas exist, how much megabyte bloat is tied to unused formatting, the presence of hidden macro code, and any dangerous external data links.

Step-by-Step Usage

1. Upload your sluggish or problematic .xlsx file.
2. Click the 'Run Deep Audit' button.
3. The engine parses the XML structures, caches, and formula logic.
4. Review the comprehensive Health Dashboard.
5. Identify critical warnings (e.g., '45 Broken External Links Found').
6. Download the diagnostic PDF report.

Key Benefits

• Finds the Bloat: Tells you exactly why your file is 50MB (e.g., revealing a massive, hidden 40MB Pivot Cache).
• Security Check: Highlights the presence of VBA macros, hidden developer sheets, and external API connections.
• Formula Health: Quantifies the exact number of calculation errors (`#N/A`, `#REF!`, `#DIV/0!`) polluting your workbook.

Real-World Use Cases

IT Helpdesk technicians run this tool on user files that are crashing the network drive to identify formatting bloat. Financial reviewers audit complex valuation models received from third parties to identify hidden data and broken logic strings. Freelancers check their final deliverables to ensure no hidden scratchpad data is sent to the client.

Pro Tips

Use the generated Audit Report as a 'To-Do' list. If the report highlights '1,000,000 Empty Formatted Cells', you know you need to go run our 'Clear Formatting' tool. If it highlights 'Very Hidden Sheets', you know to run the 'Remove Hidden Sheets' tool. It is the ultimate first-step diagnostic for any messy spreadsheet.

Top Use Cases

• Diagnosing why an Excel file is operating extremely slowly or freezing
• Auditing a client-provided financial model for broken logic references
• Checking a file for hidden, sensitive data before public distribution
