What is SQL Formatter?
SQL Formatter beautifies messy, single-line, or inconsistently indented SQL into a clean, readable query with proper line breaks and alignment. Pick your database dialect and keyword casing, and the formatted query updates live as you type. It supports Standard SQL, PostgreSQL, MySQL, SQLite, SQL Server, and BigQuery. Everything runs in your browser, so your queries are never uploaded.
How to use SQL Formatter
Paste your SQL
Drop a query into the Input box, or click Load file to open a .sql file. A sample query is loaded so you can see the formatting immediately.
Choose your dialect
Select the database you write for — Standard SQL, PostgreSQL, MySQL, SQLite, SQL Server (T-SQL), or BigQuery — so dialect-specific syntax is formatted correctly.
Set keyword casing
Pick UPPERCASE, lowercase, or Preserve for keywords like SELECT and JOIN. The formatted output re-renders instantly whenever you change an option.
Review the result
The right pane shows your query with consistent indentation, clause-per-line layout, and aligned conditions. Malformed SQL shows a friendly red message instead of crashing.
Copy or download
Use Copy to grab the formatted query, or Download to save it as formatted.sql for your migration, script, or repository.
