Private Analysis
Analyze local files without uploading data
SQL for Files is designed for sensitive ad-hoc analysis: files, imported tables, SQL queries, and results stay in browser storage unless you export them.
No account required
File processing and SQL execution run locally in the browser
IndexedDB stores persisted tables and query history on your device
Useful when AI can help draft SQL but should not receive underlying data
Example queries
Profile a sensitive export locally
SELECT status, COUNT(*) AS rows
FROM customer_export
GROUP BY status
ORDER BY rows DESC;Check missing data
SELECT COUNT(*) AS missing_email_rows
FROM customer_export
WHERE email IS NULL;
