SQL Formatter

The tool supports standard SQL along with specific dialects like MySQL, PostgreSQL, SQLite, MariaDB, SQL Server (T-SQL), BigQuery, and Snowflake.

Yes. This tool is 100% client-side. The formatting happens entirely within your web browser using JavaScript. No queries or table names are ever uploaded to our servers.

Clicking the "Minify" button will collapse your formatted SQL into a single line, stripping out unnecessary whitespace and comments to reduce file size.

Unformatted SQL is incredibly difficult to read, debug, and maintain. Formatting your queries adds consistent indentation and capitalization, making complex JOINs and subqueries easy to understand at a glance.

No. The tool only modifies whitespace (spaces, tabs, newlines) and keyword capitalization (e.g., changing select to SELECT). The actual execution logic of your SQL remains completely untouched.

By default, the tool will uppercase all standard SQL keywords (like SELECT, FROM, WHERE, INNER JOIN) to make them stand out from your table names and column variables. You can toggle this off if you prefer.

Yes! If you paste a script containing multiple queries separated by semicolons (;), the tool will perfectly format each individual query and maintain the separation between them.

Both single-line comments (-- comment) and multi-line comments (/* comment */) are fully preserved and indented correctly alongside your SQL code.

Absolutely. Because it runs entirely in your browser, there are no usage limits, API quotas, or costs. You can use it freely for both personal and enterprise database tasks.

Yes, the tool is capable of formatting complex structures like stored procedures, functions, and triggers, properly indenting the BEGIN/END blocks for readability.
