How to Format SQL Queries
The SQL Formatter pretty-prints your queries with proper indentation, keyword uppercasing, and alignment — supporting PostgreSQL, MySQL, and SQLite dialects.
- Paste your SQL query into the editor.
- Select your SQL dialect (PostgreSQL, MySQL, SQLite, or standard SQL).
- Click Format and copy the beautified query.
Why Format SQL?
Formatted SQL is dramatically easier to read, review, and debug. Consistent indentation reveals the structure of JOINs, subqueries, and CTEs. Uppercased keywords (SELECT, FROM, WHERE) distinguish SQL syntax from table and column names. Most teams enforce SQL formatting in code reviews.
Why Use Our SQL Formatter?
- Multi-dialect — PostgreSQL, MySQL, SQLite, and ANSI SQL.
- Keyword uppercasing — SELECT, FROM, WHERE stand out from identifiers.
- Indent control — customize indentation width.
- Client-side — your queries never leave the browser.
Frequently Asked Questions
Does it validate SQL syntax?
The formatter formats the structure of your SQL but does not validate it against a database schema. Syntax errors in the original query will be preserved in the formatted output.
Can it format stored procedures?
Basic stored procedure syntax is supported, but complex dialect-specific blocks (PL/pgSQL, T-SQL) may not format perfectly.
Does it handle CTEs and window functions?
Yes. Common Table Expressions (WITH), window functions (OVER/PARTITION BY), and subqueries are all formatted with proper indentation.
Is my query data private?
Yes. All formatting happens in your browser. No SQL is sent to any server.
