SQL Formatter
Format nested SQL statements with customized spacing, capitalized keyword queries, list indentations, and standard clause line separations in the browser.
How to Format SQL Queries Across Dialects
- Select your target database dialect (PostgreSQL, MySQL, SQL Server, BigQuery, Standard SQL, or SQLite).
- Paste unformatted or nested SQL queries into the raw query editor or load a dialect-specific sample.
- Configure indentation (2 spaces, 4 spaces, tab), keyword casing, type/function casing, and AND/OR clause alignment.
- Download the formatted
.sqlscript or copy it directly to your clipboard.

AND/OR). - Interactive Dialect Samples: One-click sample loader for testing authentic dialect syntaxes.
- Comparison Matrix: Embedded engine reference table highlighting quote styles, parameter formats, and pagination rules.
Frequently Asked Questions
Which database dialects are supported?
The formatter supports PostgreSQL, MySQL, SQL Server (T-SQL), Google BigQuery, Standard ANSI SQL, and SQLite dialects.
Are my database queries secure?
Yes, 100% private. All formatting and parsing happens entirely client-side inside your browser sandbox. No query parameters or schema names ever leave your device.
