Beautify messy SQL queries with clean multi-level indentation and automated keyword capitalization (SELECT, FROM, WHERE, JOIN, GROUP BY, etc.).
Runs 100% client-side in your browser — your private database queries, table structures, and sensitive filters are never uploaded to any remote server.
Frequently asked questions
Does this tool upload my SQL?
Never. All parsing, indentation, and minification happen entirely within your local browser JavaScript engine.
Which SQL dialects are supported?
Standard ANSI SQL, MySQL, PostgreSQL, SQLite, MariaDB, and SQL Server.
Can I minify SQL to a single line?
Yes — click "Minify" to strip comments and redundant whitespace, ready to embed in an application config or a code literal.
