Why Use Use a Client-Side SQL Formatter?
Writing SQL is hard enough without having to manually indent every line. When you're debugging query logs or inheriting legacy code, you often get a wall of text. Traditional online formatters might send your private queries (which could contain table names, schema info, or even data) to their servers. This tool guarantees privacy by running the formatting logic entirely in your web browser.
Frequently Asked Questions
Is my SQL data safe?
Absolutely. This tool runs entirely in your browser. Your queries, table names, and data are never transmitted to our servers or any third party.
What SQL dialects are supported?
This is a general-purpose formatter that works well with standard ANSI SQL, widely used by MySQL, PostgreSQL, SQL Server, and SQLite. It focuses on properly indenting major keywords.
Does it validate my SQL syntax?
No, this tool purely strictly formats the text based on keywords. It does not check if the SQL is syntactically valid or executable.
Can I format a large dump file?
You can, but performance depends on your browser and computer since it runs client-side. For massive multi-megabyte dumps, a dedicated CLI tool might be faster.
Is it offline-friendly?
Yes, once the page loads, you can disconnect from the internet and continue formatting queries indefinitely.
Does it support Stored Procedures?
It will identify keywords within stored procedures, but complex nested logic within PL/SQL or T-SQL blocks might need manual fine-tuning.
