SQL Formatter

What is SQL formatting?

SQL formatting takes a query written on one long line, or with inconsistent spacing, and restructures it with clause breaks and indentation so the logic is easy to follow. Keywords line up, subqueries are indented, and conditions are laid out clearly. This tool formats SQL across MySQL, PostgreSQL, SQLite, and MSSQL dialects, with configurable keyword casing.

Why format your SQL?

Readable SQL is easier to debug, review, and maintain. A well-formatted query makes it obvious where the JOINs are, which conditions belong to which clause, and how subqueries nest, all of which reduce mistakes. In a team, consistent formatting also makes code reviews faster and version-control diffs cleaner, since changes are not buried in reformatting noise.

Keyword casing and dialects

A common convention is to uppercase SQL keywords (SELECT, FROM, WHERE) while keeping table and column names in their natural case, which makes the structure stand out. Different database systems add their own keywords and syntax, so choosing the matching dialect helps the formatter handle dialect-specific features correctly, including complex statements and stored procedures.

Your queries stay private

Formatting happens entirely in your browser. The SQL you paste is never sent to a server, so it is safe to format queries that reference real schema, table names, or business logic you would not want to share. Keep your formatted queries in version control to maintain a consistent style across the codebase.
