SQL Formatter & Beautifier

Format, beautify, and minify SQL queries. Instantly prettify your SQL with proper indentation and keyword casing.

How It Works

This tool tokenizes your SQL input and reformats it with proper indentation and keyword casing. All processing happens entirely in your browser — no data is sent to any server.

• Format — parses the SQL and re-indents it with consistent spacing, placing major clauses on new lines
• Minify — collapses all whitespace to produce a compact single-line query
• Keyword Case — converts SQL keywords to UPPER, lower, or preserves the original casing
• Syntax Highlighting — the output uses color-coded highlighting for keywords, strings, numbers, functions, and comments

About SQL

SQL (Structured Query Language) is the standard language for managing and querying relational databases. It is used by virtually all relational database systems including MySQL, PostgreSQL, SQLite, SQL Server, and Oracle.

Supported Statements

• Queries — SELECT, FROM, WHERE, JOIN, GROUP BY, HAVING, ORDER BY, LIMIT, UNION
• Data Manipulation — INSERT, UPDATE, DELETE, MERGE, REPLACE
• Data Definition — CREATE, ALTER, DROP, TRUNCATE, RENAME
• Control — CASE/WHEN/THEN/ELSE/END, IF, BEGIN/END
• Subqueries — nested SELECT statements with proper indentation

Formatting Rules

• Major clauses (SELECT, FROM, WHERE, etc.) start on new lines
• JOIN clauses are placed on new lines at the same level as FROM
• AND/OR conditions are placed on new lines with indentation
• Comma-separated items in SELECT lists are placed on individual lines
• Parenthesized subqueries are indented one level deeper
