What is SQL Beautifier?

SQL Beautifier is a free online tool for formatting and beautifying SQL queries. Unlike a basic formatter, the beautifier focuses on making SQL code as readable as possible: uppercase keywords for visibility, aligned clauses, proper indentation of subqueries, and consistent comma placement. It is designed for developers who want clean, presentation-ready SQL.

How to Use SQL Beautifier

1. Paste your SQL query into the input area. 2. Choose formatting options: keyword case (UPPER, lower, or preserve), indentation size (2 or 4 spaces), and comma placement (trailing or leading). 3. The beautified SQL appears instantly in the output area. 4. Click Copy to copy the result. The beautifier handles SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, and other common SQL statements.

How SQL Beautifier Works

The beautifier tokenizes the SQL input into keywords, identifiers, strings, numbers, and operators. It then applies formatting rules: major keywords (SELECT, FROM, WHERE, JOIN) start on new lines, sub-keywords (AND, OR, ON) are indented under their parent clause, column lists after SELECT are split one per line, and all SQL keywords are converted to the selected case. Parenthesized subqueries receive additional indentation.

Common Use Cases

  • Formatting SQL queries for code reviews and pull requests
  • Making complex queries readable for documentation
  • Standardizing SQL coding style across a team
  • Cleaning up auto-generated SQL from ORMs or query builders
  • Preparing SQL examples for technical blog posts or tutorials

Frequently Asked Questions

What is the difference between SQL beautifier and SQL formatter?▼

A SQL formatter adds basic indentation and line breaks. A SQL beautifier goes further with uppercase keywords, aligned clauses, split column lists, and consistent comma style. The beautifier produces more readable, presentation-quality SQL.

Does it support all SQL dialects?▼

The beautifier handles standard SQL syntax including SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, JOIN, GROUP BY, HAVING, and subqueries. It works with MySQL, PostgreSQL, SQL Server, SQLite, and Oracle SQL for common queries.

Can I choose the keyword case?▼

Yes. You can choose uppercase (SELECT), lowercase (select), or preserve the original case. Uppercase is the most common convention for SQL readability.

Is my SQL sent to a server?▼

No. All formatting happens entirely in your browser using JavaScript. Your SQL queries never leave your machine.
