SQL Formatter

Input SQL

Formatted SQL

Format SQL queries instantly with our online SQL formatter. Support for 16 SQL dialects including MySQL, PostgreSQL, SQLite, and BigQuery. Paste messy SQL and get clean, readable, properly indented code.

How to Format SQL

Paste your SQL query into the input panel and select the appropriate SQL dialect from the dropdown. The formatted output appears instantly in the right panel with proper indentation, line breaks, and keyword capitalization. Each SQL dialect has slightly different syntax rules, so selecting the correct one ensures the formatting matches your database platform. Copy the formatted SQL when you are ready to use it.

Why Format SQL?

Well-formatted SQL is significantly easier to read, debug, and maintain. When queries are crammed onto a single line, it becomes difficult to identify logical errors, missing clauses, or incorrect joins. Proper formatting separates clauses onto individual lines, aligns keywords, and adds consistent indentation that reveals the query's structure at a glance. Formatted SQL also reduces merge conflicts when working with version control, as changes are easier to identify.
