What is SQL Formatter?

SQL Formatter is a free developer utility that organizes long single-line SQL queries or complex JOIN, WHERE, and GROUP BY clauses into a readable structure.

Useful for SQL generated by Django ORM, database log queries, admin statistics queries, reporting SELECT statements, SQL reviews, and query refactoring.

Supported Features

  • Line-break formatting for SELECT, FROM, WHERE, JOIN, GROUP BY, and ORDER BY clauses
  • 2-space, 4-space, and tab indentation options
  • SQL keyword uppercase or lowercase conversion
  • Single-line SQL minification
  • SQL comment removal option
  • SELECT, JOIN, WHERE, line count, character count, and compression rate statistics
  • Copy formatted results and download SQL files

Useful For

  • Cleaning up single-line SQL logs
  • Analyzing queries from Django ORM or database consoles
  • Understanding queries with many JOIN clauses
  • Separating WHERE, GROUP BY, and ORDER BY conditions clearly
  • Standardizing SQL keyword style for team conventions
  • Saving cleaned queries as .sql files
How do I use auto format?

When enabled, the result area updates automatically using the selected indentation and keyword-case options as you type SQL.

When should I use SQL comment removal?

Enable comment removal to exclude -- comments and /* block comments */ from the result when preparing queries for sharing or documentation.

What is the difference between uppercase and lowercase keywords?

They do not change SQL execution results, but they help improve readability and match team conventions. Major keywords such as SELECT, FROM, and WHERE are often written in uppercase.

How is compression rate calculated?

Compression rate compares the original SQL length with the result SQL length and displays the percentage reduction.

Does it automatically fix SQL syntax errors?

No. This tool organizes SQL strings for readability. It does not fully validate or fix invalid table names, column names, missing parentheses, or DBMS-specific syntax differences.

Can I enter sensitive SQL?

Remove sensitive table names, personal data conditions, tokens, customer identifiers, or production secrets before entering or sharing queries.
