SQL Formatter — Beautify Queries in One Click [2026]

Paste messy SQL → get properly indented, uppercase-keyword output instantly. Supports SELECT, JOIN, subqueries, and DDL statements. Works with MySQL, PostgreSQL, and more.

What is SQL Formatter?

SQL Formatter is a free online tool that beautifies and formats SQL queries for better readability. It converts messy, single-line SQL into well-structured, indented code with uppercase keywords. This makes SQL easier to read, debug, and maintain, especially for complex queries with multiple JOINs, subqueries, and WHERE conditions.

How to Use SQL Formatter

Paste your raw SQL query into the input area on the left. The tool will automatically format it with proper indentation, uppercase keywords, and newlines before major clauses. You can adjust the indentation size. Copy the formatted SQL with one click and paste it into your editor or documentation.

How SQL Formatter Works

The tool parses the SQL input and identifies keywords such as SELECT, FROM, WHERE, JOIN, ORDER BY, GROUP BY, HAVING, INSERT, UPDATE, DELETE, CREATE, ALTER, and DROP. It converts all keywords to uppercase, adds newlines before major clauses, and applies consistent indentation to nested elements like column lists and conditions.

Common Use Cases

  • Formatting messy SQL queries from ORM-generated output
  • Beautifying SQL before adding it to documentation or code reviews
  • Making complex multi-JOIN queries readable for debugging
  • Standardizing SQL coding style across a development team
  • Preparing SQL statements for technical presentations

Frequently Asked Questions

What SQL dialects are supported?

The formatter works with standard SQL syntax that is common across MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. It handles all major keywords and clause structures.

Does the formatter change the meaning of my SQL?

No. The formatter only changes whitespace, indentation, and keyword casing. The logical meaning of your SQL query remains exactly the same.

Can it handle subqueries?

Yes. The formatter recognizes parenthesized subqueries and applies indentation to nested SELECT statements for improved readability.

Is my SQL data sent to a server?

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

Does it support stored procedures?

The formatter handles standard SQL statements including CREATE, ALTER, and DROP. For complex stored procedure syntax, the formatting covers the SQL portions of the code.
