Why Format SQL Code?

SQL queries can become complex very quickly, especially when involving multiple joins, subqueries, and conditions. Writing or maintaining unformatted SQL is prone to errors. Formatting your SQL helps in:

Readability: Clear structure allows you to understand the logic flow immediately.
Debugging: Spotting missing parentheses or keywords is much easier in formatted code.
Collaboration: Standardized code style ensures that your team can read and review your queries without friction.
Documentation: Clean code serves as better documentation for future maintenance.

Example Transformation

Before (Minified/Messy)

SELECT u.name, o.order_date, SUM(oi.price) as total FROM users u JOIN orders o ON u.id = o.user_id JOIN order_items oi ON o.id = oi.order_id WHERE o.status = 'completed' GROUP BY u.name, o.order_date ORDER BY total DESC;

After (Formatted)

SELECT
  u.name,
  o.order_date,
  SUM(oi.price) as total
FROM
  users u
  JOIN orders o ON u.id = o.user_id
  JOIN order_items oi ON o.id = oi.order_id
WHERE
  o.status = 'completed'
GROUP BY
  u.name,
  o.order_date
ORDER BY
  total DESC;

Frequently Asked Questions

Does this tool execute the SQL?

No, this is purely a formatting tool. It processes the text in your browser to make it pretty. It does not connect to any database or execute any queries.

Is my SQL code safe?

Yes, the formatting happens entirely on the client-side (in your browser). Your SQL queries are never sent to our servers.

Can it format PL/SQL or T-SQL?

It works best with standard SQL. While it may handle some dialect-specific keywords gracefully, complex procedural blocks might not be perfectly indented.
