SQL Formatter
Beautify & indent SQL queries.
Runs entirely in your browser — nothing you enter is uploaded, logged, or tracked.
Paste a messy SQL query to get it cleanly formatted — consistent indentation, keywords aligned, and each clause on its own line — with support for several dialects including PostgreSQL, MySQL, SQLite and BigQuery. Choose keyword casing and copy the result.
Frequently asked questions
Which SQL dialects are supported?
Standard SQL plus PostgreSQL, MySQL, MariaDB, SQLite, BigQuery, Snowflake, Db2 and more — pick the dialect so clauses specific to it format correctly.
Does it run my query?
No. It only formats the text — it never connects to a database or executes anything. Formatting happens entirely in your browser.
Can it change keyword casing?
Yes — make keywords uppercase, lowercase, or leave them as they are.
