What is sql formatter?
Minified or hand-written SQL is hard to read and easy to get wrong. A few seconds of formatting turns a dense one-liner into a clearly indented, skimmable query that you can debug, review, and share with confidence.
This formatter understands the grammar of the major SQL dialects — MySQL, PostgreSQL, SQLite, MariaDB, BigQuery, and T-SQL — so keywords, joins, and subqueries are indented correctly for each. The entire formatting step runs in your browser; your queries stay private.
How to use it
-
Paste your SQL
Any query, however messy — the formatter handles one-liners and minified code.
-
Pick your dialect
Select the database flavor so reserved words and syntax are handled correctly.
-
Tune and copy
Toggle keyword uppercase or tab indentation, then copy the cleaned query.
Examples
A messy one-liner becomes readable
Formatting separates the columns, tables, and conditions onto their own lines.
select id,name from users where id=1 and active=true order by name desc
Result: SELECT id, name FROM users WHERE id = 1 AND active = true ORDER BY name DESC
