SQL Formatter
Beautify messy SQL — supports PostgreSQL, MySQL, SQLite, and T-SQL dialects.
What is the SQL Formatter?
The SQL Formatter takes unreadable, single-line database queries and beautifies them with proper indentation, capitalization, and logical structure.
Whether debugging a complex JOIN or reviewing query performance blocks, cleanly formatted SQL is a basic requirement for developer productivity. This formatter runs instantaneously offline.
Frequently Asked Questions
Why format SQL code?
Massive raw queries spit out by ORMs or raw database dumps are practically unreadable. Formatting aligns JOINs and WHERE clauses, exposing syntax logic and potential data leaks immediately.
Is my proprietary logic safe?
Yes, this formatter executes via client-side JavaScript. Your proprietary database schemas and sensitive queries are never transmitted outside of your device.
Does uppercase matter in SQL?
To the database, SQL is completely case-insensitive. However, capitalizing reserved keywords (SELECT, FROM, WHERE) is the universal best practice for human readability.
Can it handle specific database dialects?
Yes, the tool supports Standard SQL, PostgreSQL, MySQL, SQLite, and T-SQL dialects with dialect-specific formatting rules.
Will formatting alter query execution?
No. Databases compile away all whitespace and line breaks before executing. A beautifully formatted query performs exactly identical to a single-line minified query.
