SQL Formatter
Reformat a SQL query with consistent keyword casing, clause line breaks, and indented column lists. Runs entirely in your browser.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
Example shown — replace it with your own query.
How it works
- Paste a SQL query.
- Keywords like SELECT, FROM, WHERE, and JOIN are cased consistently and pushed onto their own lines.
- Column lists in SELECT, GROUP BY, ORDER BY, and VALUES are broken one-per-line and indented.
- Copy the formatted result.
FAQ
Does this work for INSERT and UPDATE statements too, not just SELECT?
Yes — SELECT, INSERT, UPDATE, and DELETE all get keyword casing and clause line breaks.
Will string literals get mangled?
No — text inside single-quoted string literals (like '2024-01-01') is protected before any whitespace collapsing or keyword casing runs, so values are never altered.
How does it handle deeply nested subqueries?
It formats clauses and comma-separated lists reliably for typical queries, but this is a string-based formatter, not a full SQL parser — very deeply nested or vendor-specific syntax may not indent perfectly.
Is my SQL uploaded anywhere?
No — formatting happens entirely in your browser. Nothing is sent to a server.

For quickly cleaning up a query before pasting it into a PR, a Slack message, or documentation, this beats opening a full database client just to reformat text.
