SQL Formatter

Make large SQL queries readable without pasting them into a formatter you do not trust. Good for review, debugging, incident response, and documentation prep.

All formatting happens locally; no SQL data leaves your browser.

Format first, then share

If your SQL contains customer data, internal table names, or business logic, format it locally first and redact anything sensitive before pasting it into docs or tickets. See how to format SQL queries safely for the full workflow.

How do I format SQL queries for code review?

Format the query, keep joins and filters on readable lines, then review whether the change affects logic or only spacing. Before sharing a formatted query in a ticket or pull request, redact customer values, internal IDs, and production-only table names if they are not needed for the review.

Does formatting SQL change the query result?

Whitespace and indentation should not change SQL results, but manual edits made during cleanup can. Treat the formatter as a readability step, then run the query in your database or test environment if the output will be used in production.

FAQ

No. The SQL formatter runs entirely in your browser, so your queries never leave your machine. This is ideal for sensitive production queries or customer data.

The formatter handles standard SQL syntax (SELECT, FROM, WHERE, JOIN, etc.) and common extensions. For complex vendor-specific syntax, results may vary, but basic formatting works across most dialects.

Yes, but very large queries (10,000+ lines) may slow down browser performance. For massive files, consider splitting them into smaller chunks or using a desktop SQL formatter.
