/* SQL Formatter */

How to Format SQL Queries Online

Writing and maintaining SQL queries can become challenging as complexity grows. Our SQL Formatter is designed to help you quickly reorganize raw database queries into a highly readable and standardized layout. To get started, copy your raw SQL query from your application code, command line tool, or database manager, and paste it into our editor. With a single click of the Format button, the tool processes your code entirely within your browser.

• Paste your SQL: Works with standard SQL, MySQL, PostgreSQL, Oracle, SQL Server, and SQLite.
• Click Format: Instantly capitalizes SQL commands, places major clauses on separate lines, and applies indentations.
• Use Minify: Compress queries for production use in configuration files or codebases where space is premium.
• Copy or Download: Grab your clean, formatted SQL with the copy button or save it as a file.

Standardizing SQL with Capitalization and Joins

✨ Keyword Capitalization

A standard convention in database administration is to write SQL commands in uppercase while keeping table names and column names in lowercase. Our formatter scans your input query and capitalizes primary keywords such as SELECT, INSERT, UPDATE, DELETE, FROM, JOIN, WHERE, GROUP BY, ORDER BY, HAVING, and LIMIT. This makes it instantly clear what actions the query is performing versus which database schemas it is acting upon.

📂 Splitting Joins and Major Clauses

Long queries with multiple joins can easily stretch across the screen, making them hard to follow. The tool automatically splits statements at JOIN clauses (including LEFT JOIN, RIGHT JOIN, and INNER JOIN). By starting each join on a new line and aligning them vertically, you can trace database relations and connection keys with ease.

🔧 Safe Token Processing

Our tool uses a precise extraction technique that isolates string literals and comments before applying formatting rules. This ensures that any SQL keywords inside single quotes or within SQL comments are left completely untouched, preserving the integrity of your literal values.

SQL Minification and Performance Optimization

While readable SQL is critical for developers, minified SQL is often preferred for application performance. Minifying your SQL queries involves stripping out comments and collapsing extra spaces or newlines into a single line. This reduces the file size of your source code and keeps configuration files clean.

To minify a query, paste it and click the Minify button. The engine safely parses out line and block comments, cleans up excessive whitespace around operators and separators, and outputs a single-line query ready for insertion into environment files or API payloads. Doing so reduces network transfer size and prevents clutter in server logs, while preserving structural execution.
