Why Format SQL?

Properly formatted SQL is easier to review during code reviews, faster to debug when queries return unexpected results, and simpler to maintain as your schema evolves. This tool respects indentation, commas, and clause boundaries so you can spot joins, filters, and subqueries at a glance.

Supported SQL Dialects

Choose from Standard SQL, MySQL, PostgreSQL, SQLite, T-SQL (SQL Server), and PL/SQL (Oracle). Each dialect handles vendor-specific keywords, quoting styles, and function syntax correctly so your formatted output matches the database you actually use.

How to Use This Tool

  • Paste or type your raw SQL in the left panel
  • Select your target dialect from the dropdown
  • Click Format SQL or press Ctrl+Enter to pretty-print
  • Click Minify to strip whitespace and comments for compact storage
  • Copy the result with one click

Privacy and Security

Your SQL never leaves the browser. All formatting and minification happen client-side using the open-source sql-formatter library, so sensitive queries containing table names, column values, or business logic stay on your machine.

FAQs

Does SQL formatting differ between dialects?

Yes. MySQL, PostgreSQL, SQLite, T-SQL, and PL/SQL have different syntax for things like string quoting, identifier quoting, and proprietary functions. This tool supports multiple dialects via the dropdown selector.

Should SQL keywords be uppercase or lowercase?

SQL keywords are case-insensitive, but the convention is to use UPPERCASE for keywords (SELECT, FROM, WHERE) and lowercase for identifiers. This improves readability and is the default formatting in this tool.

How are subqueries formatted?

Subqueries are indented one level inside their parentheses, with the inner SELECT, FROM, and WHERE on their own lines. This makes complex nested queries much easier to read and debug.

Are SQL comments preserved during formatting?

Yes. Both single-line comments (-- comment) and multi-line comments (/* comment */) are preserved in their original position during formatting.

What does minify mode do?

Minify mode removes all unnecessary whitespace and line breaks from SQL, producing a single-line query. This is useful for logging, embedding SQL in code strings, or reducing payload size.
