SQL Formatter

Pretty print SQL queries for debugging, reviews, and documentation. Formatting runs locally and does not validate against a database engine.

SQL Formatting notes

What is SQL Formatting?

SQL formatting rewrites database queries with line breaks, indentation, and keyword casing to make them easier to read and review.

How does the SQL Formatting tool work?

The formatter normalizes whitespace, places common SQL clauses on new lines, breaks comma-separated fields, and highlights join and condition structure.

When should you use SQL Formatting?

  • Cleaning up copied SQL queries from logs
  • Preparing SQL snippets for code reviews
  • Making generated queries easier to inspect
  • Documenting database examples

What are the limitations of SQL Formatting?

  • The formatter does not validate SQL syntax
  • Vendor-specific SQL dialects may need manual adjustment
  • Complex nested queries may still require dedicated SQL tooling

SQL Formatting examples

select select * from users where active=true -> SELECT on separate lines
join left join orders on ... -> JOIN and ON line breaks
fields id,email,name -> Comma-separated field lines
