Format SQL without executing it

SQL Formatter

Make common SQL statements easier to read without executing a query or connecting to a database. Quoted strings, comments, and statement order remain source text.

Enter source text to begin.

Common SQL structure

The formatter recognizes common SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, WITH, JOIN, CASE, GROUP BY, ORDER BY, HAVING, and UNION structure.

No query execution

SQL remains inert source text. No database connection is opened, no query is validated against a schema, and no dialect-specific service is called.

Quoted values stay intact

Single-quoted strings, quoted identifiers, comments, commas, semicolons, and SQL keywords inside quoted text are tokenized without rewriting their contents.

Practical input limit

Input is limited to 6 MB of text. Small files, common 100 KB and 1 MB inputs, and representative 5 MB workloads are supported locally; larger work should use a streaming or command-line workflow.
