SQL formatter

Format SQL into readable clauses or minify it into a compact single line. The formatter uppercases common SQL keywords and supports SELECT, INSERT, UPDATE, DELETE, joins, grouping, ordering, and CTEs.

Beautify or minify

Beautified SQL is easier to review and debug. Minified SQL can reduce payload size when whitespace and comments are unnecessary.

SELECT id, name
FROM users
WHERE active = 1
ORDER BY name;

Use this tool for query reviews, documentation, demos, and quick cleanup before storing SQL in source code.

Frequently Asked Questions

Which SQL dialects are supported?: The formatter supports standard SQL keywords used across MySQL, PostgreSQL, SQLite, and SQL Server. Dialect-specific syntax is not validated.
What does the formatter change?: It uppercases SQL keywords (SELECT, FROM, WHERE), adds line breaks after clauses, and indents sub-queries and CASE statements for readability.
Can I minify SQL?: Yes. Minify mode collapses the query to a single line with minimal whitespace, useful for embedding SQL in code strings.
Is my SQL sent to a server?: No. Everything runs in the browser. Your queries are never transmitted or stored.
