Frequently Asked Questions
What is a SQL formatter?
A SQL formatter is a tool that takes raw or minified SQL queries and rewrites them with consistent indentation, line breaks, and keyword casing so they are easier to read, review, and debug. It does not change query behavior, only its appearance.
Is this SQL formatter free?
Yes. The NitroClaw SQL Formatter is 100% free, requires no signup, and has no usage limits. Format as many queries as you want, as often as you want.
Does it support MySQL, PostgreSQL, and SQL Server?
Yes. Pick the dialect from the dropdown - MySQL, PostgreSQL, SQL Server (T-SQL), SQLite, BigQuery, MariaDB, Oracle (PL/SQL), Redshift, Snowflake, DB2, and Trino are all supported, plus a generic standard SQL mode.
Is my SQL sent to a server?
No. Formatting runs entirely in your browser. Your queries never leave your machine, which makes the tool safe to use on production schemas, internal table names, and queries containing sensitive identifiers.
How do I format a long SQL query?
Paste the query into the input box, choose your dialect (or leave it on Standard SQL), pick an indent size and keyword case, then click Format. The pretty-printed result appears on the right with a Copy button so you can paste it straight back into your IDE or pull request.
