What is SQL Formatter?

The SQL Formatter takes raw, messy, minified, or machine-generated SQL and converts it into a clean, readable, properly formatted query. SQL queries often become difficult to read when exported from tools, concatenated in applications, or generated by ORMs. This formatter restructures SQL with proper indentation, capitalization, keyword highlighting, and line breaks. It supports multiple SQL dialects and is ideal for database engineers, software developers, data analysts, DBAs, and students learning SQL.

Frequently Asked Questions

Is this SQL formatter free?

Yes. It is 100% free and always will be.

Can I format SQL without uploading it?

Yes. All processing happens locally in your browser. Your queries remain private and never leave your device.

Which SQL dialects are supported?

I support all major dialects! Whether you use MySQL, PostgreSQL, MariaDB, SQL Server, Oracle, or SQLite, I can format your queries perfectly.

Will this tool support stored procedures and functions?

Yes. It supports complex multi-line SQL statements, including stored procedures, triggers, and functions.

Can it format very large SQL files?

Yes. It supports large and multi-line SQL queries, limited only by your browser's memory.

Does this tool work offline?

Yes. No internet connection is required after loading the page.

Does it validate my SQL?

I focus mainly on beautification. While I can catch some basic syntax errors, I don't execute the query against your database.
