- Works with Excel (.xlsx, .xlsm) and Google Sheets files
- Hardcoded number and broken formula risk scoring
- Customizable exceptions engine — you define the audit logic
- Local processing — zero third-party data exposure
Built for high-stakes spreadsheet managers
What HSAA catches before your boss does
A focused audit layer that scans your workbook for the mistakes that destroy credibility.
Universal File Support
Examines Microsoft Excel (.xlsx, .xlsm) and Google Sheets files directly — no add-on, plugin, or extension required.
Hardcoded Values & Formula Errors
Flags hardcoded numbers, broken references, mismatched ranges, and risky lookups before review.
Customizable Exceptions Engine
Retain complete control over audit logic. Edit the exceptions list to define the exact formula rules, threshold errors, and anomalies HSAA inspects — so your audit policy matches your standards, not someone else's.
Fast Audit Runs
Runs a full risk report in seconds, not hours, so you can iterate quickly.
Privacy-First by Design
Files are processed locally by the standalone engine. Zero third-party data exposure, full data sovereignty.
Cohort Feedback Loop
Beta members shape the roadmap and get direct access to the founding team.
Executive Summary
Generates a clean risk report you can paste into emails, decks, or audit files.
