Everything you need to know about using this tool effectively
The SQL Formatter beautifies SQL queries by adding consistent indentation, line breaks, and keyword casing. It supports multiple SQL dialects including MySQL, PostgreSQL, SQL Server, and SQLite. The tool handles complex queries with subqueries, joins, CTEs, and window functions. All processing happens in the browser.
This tool parses SQL text and reformats it with configurable options: indent size, keyword case (upper, lower, preserve), and comma placement (before or after). It recognizes SQL keywords, identifiers, strings, and comments to produce properly structured output.
