Which SQL dialects are supported?

The formatter works with standard SQL and is compatible with MySQL, PostgreSQL, SQLite, SQL Server, and Oracle syntax. Dialect-specific functions are passed through without modification.

Does the formatter validate SQL syntax?

No — it formats the structure using keyword-based rules. Syntax errors in your SQL are not detected. Use your database client or a linter for validation.

Can it format complex queries with CTEs and subqueries?

Yes. CTEs (WITH clauses), subqueries, JOINs, and window functions are all formatted. Very complex nesting may need minor manual adjustment.

Why should I format SQL?

Formatted SQL is significantly easier to read, debug, and review. Consistent indentation makes JOIN conditions, WHERE clauses, and column lists immediately visible.

Is my SQL sent to a server?

No. All formatting runs as pure JavaScript in your browser. Your queries are never transmitted anywhere.

Does it check whether my table and column names exist?

No. The formatter has no connection to a database and no schema awareness — it only rearranges the text of the query you give it. It can't tell you if a table or column name is misspelled or missing.

Can I use this to format an INSERT with hundreds of rows?

Yes, though very long VALUES lists are formatted the same way as any other clause — each row typically stays on its own line rather than being wrapped further, since that keeps the row count scannable.

How is this different from a SQL linter?

A linter (like sqlfluff) checks your query against style rules and can flag anti-patterns or potential bugs. This tool only handles layout — indentation, line breaks, and keyword casing — it doesn't flag logic issues.

Will formatting change what my query does?

No. Formatting only changes whitespace, line breaks, and optionally keyword casing. The parsed meaning of the query — which tables, joins, and conditions it references — is completely unchanged.

Can I format multiple statements separated by semicolons at once?

Yes, paste multiple statements and each one is formatted independently, keeping the semicolon boundaries between them.
