SQL Formatter

Make queries easier to review without connecting to a database. Select the SQL dialect, indentation and keyword case, then format locally. Quoted values and comments remain part of the query; nothing is executed.

  3. 3 Copy the formatted SQL or download a .sql file for review in your editor.

Frequently asked questions

Will this run my SQL or contact a database?

No. Formatting changes presentation only and does not execute SQL, test permissions, inspect tables or connect to a database.

Which SQL dialects can I select?

Standard SQL, PostgreSQL, MySQL, SQLite, SQL Server, BigQuery and Snowflake are available. Select the correct dialect for quoted identifiers and dialect-specific syntax.

Does it validate every SQL program?

No. A successful format is not proof of database validity. Stored procedures and custom delimiter directives are outside the formatter scope. Input is limited to 500 KB and processing stops after 10 seconds.
