Format SQL queries by dialect and make dense queries readable.
Formatting runs locally. Pick a dialect for best results.
SELECT
u.id,
u.name,
count(o.id) AS orders
FROM
users u
LEFT JOIN orders o ON o.user_id = u.id
WHERE
u.active = TRUE
GROUP BY
u.id,
u.name
ORDER BY
orders DESC;Paste a query, choose the closest database dialect, and format dense SQL into readable clauses with consistent indentation and keyword casing. This is useful for code reviews, migration scripts, query debugging, and sharing examples in documentation.
The selected SQL dialect controls keyword layout and clause indentation through the browser-side formatter. The tool focuses on making statements easier to review; it does not connect to a database or execute the query.
Example: A long SELECT with joins, filters, and an ORDER BY clause is split into readable sections so a reviewer can compare joins and conditions more easily.
Formatting is not query validation, optimization, or security review. Vendor-specific syntax may need a different dialect or manual cleanup, and the tool cannot detect slow plans, missing indexes, or injection risks.
The formatter includes common dialects such as Standard SQL, PostgreSQL, MySQL, SQLite, BigQuery, Snowflake, Spark, and T-SQL.
No. The SQL formatter runs in the browser after the page loads, so queries are not sent to CodeSphere.
Different databases use different quoting rules and functions. Choosing the closest dialect gives cleaner formatting and better parser feedback.
