Powerful Client-Side SQL Beautifier

Turn dense, single-line, or messy database queries into clean, beautifully structured SQL. Our tool supports multiple database dialects, customizable keyword capitalization (UPPERCASE / lowercase), and flexible indentation.

  • Multi-Dialect Support: Standard SQL, PostgreSQL, MySQL, SQLite, MariaDB, Transact-SQL (SQL Server), BigQuery, and Snowflake.
  • Keyword Casing: Automatically format keywords like SELECT, JOIN, WHERE, and GROUP BY in uppercase or lowercase.
  • 100% Secure & Private: Queries execute directly inside your browser. No database credentials, schema names, or table data are ever sent over the network.
  • Mobile & Tablet Optimized: Edit queries comfortably with responsive single-pane tabs on phones and split view on desktop.

How to Format SQL

Structure your database queries in 3 steps:

  1. Paste Query: Paste your unformatted or minified SQL query into the editor.
  2. Choose Dialect & Casing: Select your target database (Postgres, MySQL, etc.) and keyword casing.
  3. Format: Click Beautify to get a structured, perfectly indented query ready to paste into your database client or code.
