SQL Formatter

Improve SQL readability with quick formatting.

About SQL Formatter

SQL Formatter takes single-line, mangled, or hand-written SQL and rewrites it with consistent indentation, capitalised keywords, and clean line breaks — making complex queries easy to read in pull requests, support tickets, and team documentation.

It supports MySQL, PostgreSQL, SQL Server, SQLite, BigQuery, Snowflake, and Redshift dialects, including their CTE, window function, and JSON-operator quirks.

Reformatted into a multi-line query with aligned ON clauses.

CTE

with active_users as (select id from users where active=true) select * from active_users join orders on orders.user_id=active_users.id;

Common Table Expression broken into its own block.

Frequently Asked Questions

Which SQL dialects are supported?

MySQL, PostgreSQL, SQL Server (T-SQL), SQLite, BigQuery, Snowflake, and Redshift. Each has its own keyword set and operators — pick the matching dialect for the most accurate formatting.

Does it run my SQL?

No. It only reformats the text — it never connects to a database or executes anything. You can paste production queries safely.

Will it change my query behavior?

No. Formatting only changes whitespace and keyword case. The parsed query semantics are identical — safe to paste back into your application.

What about stored procedures and complex DDL?

The formatter handles multi-statement scripts, BEGIN/END blocks, IF/ELSE, and most procedural extensions. Very database-specific syntax (T-SQL MERGE, PostgreSQL DO blocks) may need manual touch-ups.

Can I keep my own indent style?

Yes. Choose 2 spaces, 4 spaces, or tabs, and pick leading or trailing commas. The output will match your team convention.

Are SQL comments preserved?

Yes. Single-line and multi-line comments survive formatting unchanged.

Why is my formatted query different from what an ORM produces?

ORM-generated SQL often uses parameter placeholders ($1, ?) and aggressive aliasing for safety. The formatter preserves those, but the result still looks neater than raw ORM output.
