Features & Benefits
100% Privacy Preserved
All SQL parsing and formatting operations occur entirely within your browser. Your database schema and proprietary queries are never uploaded to remote servers.
Multi-Dialect Support
Perfectly formats code for major relational databases including MySQL, PostgreSQL, MariaDB, SQL Server (T-SQL), and SQLite.
Code Readability
Transforms dense, single-line SQL queries into clean, well-indented, and structured code. Essential for debugging complex JOINs and subqueries.
Customizable Styling
Force keywords (SELECT, FROM, WHERE) to be uppercase or lowercase, and adjust your indent size to match your team's exact coding standards.
Frequently Asked Questions
What happens if my SQL has syntax errors?
The formatting engine will attempt to parse your query. If it encounters a severe syntax error that prevents parsing, it will catch the error and display a detailed message so you can fix the issue.
Does this tool execute my queries?
No. This tool only parses the text of your query to format its visual structure. It does not connect to any database or execute any SQL commands.
Is my data uploaded anywhere?
No. The formatting process happens entirely locally on your device via JavaScript. Zero data is transmitted over the internet.
