Frequently Asked Questions

What does an SQL formatter do?
It formats SQL queries with clean indentation, line breaks, and consistent capitalization. This makes complex queries easier to read, review, and debug.
Will formatting change my SQL query results?
No. Formatting only changes whitespace and layout, not query logic. Your SQL should run the same as long as the original query is valid.
Does it support different SQL dialects like MySQL or PostgreSQL?
Many formatters handle common SQL patterns across major databases. Some dialect-specific features may not format perfectly, but the query structure usually becomes much more readable.
Why does my formatted query still look messy?
The input may contain invalid syntax or unusual formatting in strings. Make sure quotes are closed and remove non-SQL text before formatting.
Is this SQL Formatter secure?
Yes. It runs 100% client-side, so your queries stay in your browser and are not uploaded to a server.
