Is SQL Formatter free?

Yes. Every VersaTools tool is completely free — no account, no watermark, and no sign-up required.

Are my queries sent to a server?

No. Formatting happens entirely in your browser using a local library, so your SQL never leaves your device.

Which databases are supported?

You can format Standard SQL, PostgreSQL, MySQL, SQLite, SQL Server (T-SQL), and BigQuery. Choosing the right dialect ensures dialect-specific syntax is handled correctly.

Does it change what my query does?

No. The formatter only adds whitespace, line breaks, and adjusts keyword casing. The query's logic and results stay exactly the same.

Why does my SQL show an error?

The formatter needs syntactically parseable SQL. If a keyword, quote, or parenthesis is malformed the tool shows a red message so you can fix that spot and try again.

How to use SQL Formatter

3 simple steps to complete your task directly in your browser:

Paste your SQL
Drop a query into the Input box, or click Load file to open a .sql file. A sample query is loaded so you can see the formatting immediately.
Choose your dialect
Select the database you write for — Standard SQL, PostgreSQL, MySQL, SQLite, SQL Server (T-SQL), or BigQuery — so dialect-specific syntax is formatted correctly.
Set keyword casing
Pick UPPERCASE, lowercase, or Preserve for keywords like SELECT and JOIN. The formatted output re-renders instantly whenever you change an option.
