Why Files Never Leaving Your Browser Matters
When you convert a spreadsheet online, the question of where the conversion happens is a privacy question. Tools that upload your file to a server mean your data — customer records, financial figures, salary information, product pricing — passes through someone else's infrastructure, even briefly.
ExcelErrorFinder processes your file using JavaScript running directly in your browser tab. The file is read from your disk into browser memory, converted, and downloaded back to your disk — without ever reaching the internet. You could disconnect from Wi-Fi after the page loads and the converter would still work.
This is especially important for:
- HR and payroll data — salary, employee records, PII
- Financial models — unreleased figures, budget data
- Customer databases — names, emails, addresses (GDPR / CCPA scope)
- Confidential pricing or product data — before public release
