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;
