FAQ
Frequently asked questions
Everything you need to know about sql formatter & beautifier.
Which SQL dialects are supported?
MySQL, PostgreSQL, SQLite, SQL Server, and standard ANSI SQL are all supported. You can also configure keyword case to UPPER, lower, or capitalize and pick the indentation style that matches your codebase.
Is my query sent to a server?
No. Formatting runs entirely in your browser using a SQL parser bundled with the page, so queries containing schema names, column names, or business data never leave your device.
Can it handle complex queries?
Yes. Subqueries, CTEs, JOINs, window functions, and CASE expressions are all indented correctly, and strings and comments are left untouched so literals keep their exact content.
Does it minify SQL?
No, this tool is a formatter only and focuses on readability. For compact output you can still run your formatted query through a minifier afterward, but there is no dedicated minify mode here.
What indentation options exist?
You can choose between 2-space, 4-space, or tab indentation, and the keyword casing option updates live. Formatting applies consistently across nested clauses so the whole query reads cleanly.
Why does my formatted query differ from my editor?
Different tools implement different formatting rules, so exact output varies by parser and style defaults. You can tweak the indentation and keyword case here to get closer to the convention your team uses.
