What SQL dialects are supported?

This formatter supports standard SQL, PostgreSQL, MySQL, SQLite, MariaDB, BigQuery, and T-SQL (Microsoft SQL Server). Select your dialect from the toolbar dropdown for optimal formatting.

Does this tool modify my query logic?

No. The formatter only changes whitespace and indentation — it never modifies keywords, table names, column names, or query logic. The formatted query is functionally identical to the original.

Can I choose keyword casing?

Yes. You can toggle between UPPERCASE and lowercase keywords using the toolbar. UPPERCASE is the most common convention and improves readability.

Does it handle subqueries and CTEs?

Yes. The formatter correctly handles subqueries, Common Table Expressions (WITH clauses), JOINs, UNION, window functions, and other complex SQL constructs with proper indentation.

Can I customize the indentation?

Yes. You can choose between 2-space and 4-space indentation using the toolbar options.

Is my SQL sent to a server?

No. All formatting is performed entirely in your browser using JavaScript. No queries are ever uploaded or transmitted.
