SQL Formatter
Paste your SQL query to format, beautify, and syntax-highlight it instantly. All processing happens in your browser.
What is a SQL Formatter?
A SQL query formatter is an essential developer tool that takes messy, unformatted SQL queries and transforms them into clean, readable, properly indented code. Whether you're working with complex SELECT statements with multiple JOINs, INSERT queries with large value lists, UPDATE operations with many SET clauses, or CREATE TABLE definitions, this SQL beautifier online reformats your code to follow consistent conventions. ToolMagic's SQL formatter features real-time syntax highlighting that colors keywords, strings, numbers, and comments differently for easy reading, adjustable indentation (2 spaces, 4 spaces, or tabs), uppercase keyword conversion, line numbers, and a minify option to compress queries. Unlike server-based SQL formatters, this tool processes everything client-side in your browser — your sensitive database queries never leave your device. It supports all major SQL statement types including SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, ALTER TABLE, DROP, and more, making it a comprehensive SQL beautifier for daily development work.

It's perfect for quick formatting tasks without switching contexts to a desktop app.

What SQL statements does the formatter support?
The formatter supports all common SQL statements including SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, ALTER TABLE, DROP, TRUNCATE, and compound statements with subqueries and JOINs.
Is my SQL query sent to a server?
No. All formatting happens client-side in your browser using JavaScript. Your SQL queries never leave your device, making it safe for sensitive database queries.
Can I minify SQL instead of formatting it?
Yes! Use the "Minify" button to compress your SQL by removing unnecessary whitespace and newlines. This is useful when embedding SQL in application code.
What indentation options are available?
You can choose between 2 spaces, 4 spaces, or tab characters for indentation. This lets you match your team's coding standards.
Does it support syntax highlighting?
Yes, the formatted output uses color-coded syntax highlighting: blue for keywords, green for strings, orange for numbers, and gray for comments.
Can I format multiple SQL statements at once?
Yes, paste multiple statements separated by semicolons and the formatter will beautify each one individually.
