Does it support all SQL dialects?

The formatter supports standard SQL and has specific handling for MySQL, PostgreSQL, and T-SQL (SQL Server) dialects via a selector.

Does it validate SQL syntax?

The formatter is structure-based, not a full SQL parser. It formats based on keyword patterns and may not catch all syntax errors.

Can I minify SQL to remove all whitespace?

Yes. Toggle to minify mode to collapse all whitespace into a single-line SQL query — useful for embedding in scripts where line breaks cause issues.

Are SQL keywords automatically uppercased?

By default yes — keywords like SELECT, FROM, WHERE, JOIN are uppercased. You can toggle case normalisation off if you prefer lowercase keywords.

SQL Formatter

Formats raw or minified SQL queries into readable, properly indented SQL with keywords uppercased and clauses aligned. Supports standard SQL, MySQL, PostgreSQL, and SQL Server dialects. Handles SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, ALTER TABLE, and complex subqueries and JOINs.

Runs entirely in your browser — your input is never uploaded, stored, or logged.

Paste your unformatted SQL and get clean, readable output ready for documentation or code review. For formatting JSON responses from your SQL queries, use the JSON Formatter.

Examples

SELECT query

Input

select id,name from users where active=1 order by name

SELECT
  id,
  name
