How SQL formatting works

The formatter tokenizes SQL into keywords, identifiers, strings, comments, numbers, operators, and punctuation. It then rebuilds the script with consistent line breaks and indentation while preserving quoted values and comments.

Dialect selection changes recognized keywords and quoting behavior. PostgreSQL mode understands dollar-quoted strings and casts, MySQL mode accepts hash comments and backticks, and SQL Server mode recognizes bracketed identifiers.

This tool does not connect to a database or prove that a query is semantically valid. Review warnings and test important statements against the correct database before deployment.

Formatting options

Readable formatting

Separate major clauses, indent lists, break complex conditions, and choose leading or trailing commas.

SQL minification

Remove unnecessary whitespace while preserving tokens, quoted content, comments, and statement boundaries.

Dialect awareness

Choose Standard SQL, PostgreSQL, MySQL or MariaDB, SQLite, or SQL Server for better token recognition.

Safety review

Spot unclosed quotes, comments, or parentheses and receive reminders about SELECT * or unrestricted data changes.

Frequently Asked Questions

Is the SQL Formatter free?+
Yes. You can format, minify, copy, and download SQL without creating an account.
Is my SQL uploaded or executed?+
No. Everything runs locally in your browser. The tool never connects to your database and cannot execute a query.
Which SQL dialects are supported?+
You can choose Standard SQL, PostgreSQL, MySQL or MariaDB, SQLite, and SQL Server. Formatting is token-based, so uncommon vendor extensions may still require manual review.
Can formatting change the meaning of a query?+
The formatter is designed to change layout and keyword casing, not values. However, SQL dialects differ, so always review and test production queries after automatic formatting.
What does minify do?+
Minification removes unnecessary whitespace and line breaks while retaining the tokens needed for valid SQL. Comments are preserved.
Does the warning panel replace database validation?+
No. It catches structural issues and risky-looking patterns, but only the target database can validate schema names, types, permissions, functions, and complete SQL semantics.
