About SQL Formatter

Messy SQL queries are hard to read, debug, and review in code reviews. Whether you are dealing with a long query generated by an ORM, a complex report query with multiple joins, or a stored procedure inherited from a colleague, proper formatting makes all the difference. This tool formats your SQL with proper indentation, keyword capitalization, and consistent spacing, transforming unreadable one-liners into clean, structured queries. It supports multiple SQL dialects including Standard SQL, PostgreSQL, MySQL, MariaDB, SQLite, BigQuery, and more, ensuring that dialect-specific syntax is handled correctly. Paste your query, choose your preferred formatting style (indentation width, keyword case), and get beautifully formatted SQL instantly. You can also minify formatted SQL back to a single line when compact queries are needed. This is essential for database developers, data analysts writing complex reports, backend engineers debugging queries, and anyone reviewing SQL in pull requests.

Frequently Asked Questions

Is my SQL sent to a server?

No. All processing happens locally in your browser. No data leaves your device.

What SQL dialects are supported?

The formatter supports standard SQL, PostgreSQL, MySQL, MariaDB, SQLite, BigQuery, Transact-SQL (SQL Server), and PL/SQL (Oracle).

Does formatting change query behavior?

No. Formatting only changes whitespace, indentation, and capitalization of keywords. The query logic and results remain exactly the same.

Can I customize the indentation style?

Yes. You can choose between spaces and tabs, adjust the indent width, and control keyword capitalization (uppercase, lowercase, or preserve).

Is my file uploaded to a server?

No. Transmute processes everything locally in your browser using JavaScript and the Canvas API. Your files never leave your device — there is no server, no upload, no cloud processing.
