In complex backend systems, SQL queries can often grow into hundreds of lines. Without proper formatting, debugging and reviewing these queries becomes a significant bottleneck for development teams.
Our Online SQL Prettifier automatically handles indentation, keyword capitalization (UPPERCASE), and logical spacing to reveal the structure of nested joins and subqueries instantly.
Developer Tip
Standardizing SQL casing (keywords in uppercase, identifiers in lowercase) is a proven way to reduce syntax errors during manual query editing.
PostgreSQL & MySQL
Full support for standard relational operators and specific syntax like JSONB or LIMIT/OFFSET.
TSQL (SQL Server)
Special handling for square brackets, TOP clauses, and stored procedure syntax.
PL/SQL (Oracle)
Optimized for Oracle's unique keyword set and data types.
SQLite
Lightweight and efficient formatting for embedded database queries.
Is my query data safe?
Yes. All formatting happens locally in your browser. We never see your queries, tables, or database structure. Perfect for internal company data.
Can I use this for complex joins?
Absolutely. Our engine is designed to handle deeply nested subqueries, CTEs (WITH clauses), and complex multi-table joins with ease.
Does it support DDL statements?
Yes! You can format CREATE TABLE, ALTER, and INDEX statements just as easily as SELECT or UPDATE queries.
Why use uppercase for keywords?
Using UPPERCASE for reserved keywords (SELECT, FROM, WHERE) makes them stand out visually from your table and column names, improving scanability.
