SQL Query Formatter
Format, beautify, and minify complex database SQL queries with customizable keyword casing, indentation, and multi-dialect support.
SQL Beautifier & Minifier
Paste unformatted SQL statements to clean keywords, line breaks, and clause structure instantly.
SELECT u.id, u.name, count(o.id) AS total_orders, sum(o.total_amount) AS lifetime_value FROM users u LEFT JOIN orders o ON u.id = o.user_id WHERE u.status = 'active' AND o.created_at >= '2026-01-01' GROUP BY u.id, u.name HAVING count(o.id) > 5 ORDER BY lifetime_value DESC LIMIT 20;
Client-Side SQL Query Formatting & Minification
Working with dense database queries, auto-generated ORM SQL output, or long database migration scripts often results in unreadable single-line strings. Reading messy SQL statements without clear clause breaks and keyword formatting slows down debugging and query optimization.
The SQL Query Formatter provides an instant, client-side visual tool to beautify messy SQL code. Customize SQL keyword capitalization (UPPERCASE vs lowercase), adjust tab indentation, format subqueries, and convert SQL statements into compact minified strings for production code embedding.
Core Tool Capabilities
- Multi-Dialect SQL Formatting: Format queries formatted for PostgreSQL, MySQL, SQLite, T-SQL (SQL Server), and ANSI SQL standards.
- Keyword Normalization: Instantly convert SQL keywords to UPPERCASE or lowercase while preserving database column names.
- Minification Engine: Compress formatted SQL queries into single-line minified strings for ORM inline queries or code bases.
- Instant Download & Copy: Copy formatted output to your clipboard or download formatted `.sql` files directly.

Inline SQL String Minification
Developers minify SQL strings before pasting them into application source code.
Frequently Asked Questions
- Does the SQL Query Formatter support PostgreSQL specific syntax?
- Yes. Selecting PostgreSQL dialect formats CTEs (WITH clauses), JSONB operators, and Postgres functions cleanly.
- Is my database query sent to any server?
- No. All SQL parsing, keyword normalization, and formatting occur Full in your browser without transmitting query data anywhere.
- Can I minify my SQL query?
- Yes. Clicking the 'Minify' button removes unnecessary whitespace and line breaks, producing a compact single-line SQL string.
- Does formatting alter column or table names?
- No. Only standard SQL keywords (SELECT, FROM, WHERE, JOIN, etc.) are converted according to your keyword casing preference.
