What is SQL formatting?

SQL formatting (also called SQL beautifying or pretty-printing) takes compact or messy SQL queries and adds proper indentation, line breaks, and consistent keyword casing to make them easy to read. Whether you are debugging a complex JOIN, reviewing a pull request, or documenting a data pipeline, formatted SQL saves time and reduces mistakes.

Why format SQL?

  • Readability: properly indented queries are easier to scan and understand at a glance.
  • Debugging: formatting reveals the structure of nested subqueries, JOINs, and WHERE clauses, making errors easier to spot.
  • Code review: consistent formatting makes diffs cleaner and reviews faster.
  • Team standards: a shared formatting style eliminates style debates and keeps codebases consistent.

Frequently Asked Questions

Does this tool change my SQL logic? No. Only whitespace, indentation, and keyword casing are modified. Your table names, column names, values, and query logic remain exactly the same.

Is my SQL sent to a server? No. All formatting runs entirely in your browser using JavaScript. Nothing is uploaded.

What SQL dialects are supported? The formatter handles standard ANSI SQL syntax and works well with MySQL, PostgreSQL, SQLite, SQL Server, and Oracle queries. Dialect-specific extensions (stored procedures, variables) may not be perfectly formatted but will be preserved.
