Free SQL Formatter

How to Format SQL Online

Paste your SQL query into the input panel and click Format. The formatter applies consistent indentation, line breaks, and keyword casing to make your query readable. Choose your SQL dialect, indentation style, and whether to uppercase keywords. Copy the formatted result or download it as a .sql file.

Supported SQL Dialects

The formatter supports Standard SQL, MySQL, PostgreSQL, SQL Server (T-SQL), and SQLite. Each dialect has its own keyword set and formatting conventions. Selecting the correct dialect ensures that dialect-specific syntax like backticks (MySQL), square brackets (SQL Server), or double-quoted identifiers (PostgreSQL) is handled properly.

Frequently Asked Questions

What SQL dialects are supported?

The formatter supports Standard SQL, MySQL, PostgreSQL, SQL Server (T-SQL), and SQLite. Select your dialect from the dropdown to get dialect-specific formatting.

Can I uppercase keywords?

Can I choose indentation?

Yes — choose between 2 spaces, 4 spaces, or tab indentation to match your team's coding style.

Is this formatter free?

Yes — completely free, forever. No sign-up, no account, no usage limits.

Is my data safe?

All formatting happens locally in your browser using JavaScript. Your SQL is never uploaded to any server. It's safe to use with sensitive or proprietary queries.
