SQL Formatter

Format and beautify SQL queries online. Supports SELECT, INSERT, UPDATE, DELETE and more.

What is a SQL Formatter?

A SQL formatter takes messy, single-line, or inconsistently formatted SQL queries and transforms them into clean, properly indented, readable code. Well-formatted SQL is easier to understand, debug, review, and maintain — especially for complex queries with multiple JOINs, subqueries, and WHERE clauses.

Our online SQL formatter handles SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, and other standard SQL statements. It works with all major SQL dialects including MySQL, PostgreSQL, SQL Server, SQLite, and Oracle.

How to Use This SQL Formatter

  1. Paste your SQL query into the input area
  2. Click “Format” to beautify the query with proper indentation
  3. Review the output — keywords are uppercased, clauses are on separate lines
  4. Copy the formatted query for use in your code or documentation
  5. Adjust and reformat as needed

Common Use Cases

  • Code reviews — Format SQL in pull requests so reviewers can easily understand the query logic
  • Debugging slow queries — Clean up EXPLAIN output and query plans for analysis
  • Documentation — Present SQL examples clearly in technical docs and READMEs
  • Legacy code cleanup — Reformat old SQL queries that have been modified by multiple developers
  • Learning SQL — Understand complex queries by seeing them properly structured

Frequently Asked Questions

Does the formatter change the meaning of my SQL?

No. Formatting only changes whitespace, line breaks, and keyword capitalization. The logical meaning and execution of your query remains identical. The database engine treats formatted and unformatted queries the same way.

Which SQL dialects are supported?

The formatter handles standard SQL syntax compatible with MySQL, PostgreSQL, SQL Server, SQLite, Oracle, and other databases. Dialect-specific extensions (like MySQL’s backtick quoting or PostgreSQL’s :: casting) are preserved.
