SQL Formatter
Format SQL queries with consistent indentation and uppercase keywords. Client-side only.
About this SQL Formatter
Format and beautify SQL queries with consistent indentation, line breaks, and optional keyword casing. Poorly formatted SQL is hard to read, debug, and review. This tool takes raw or minified SQL—whether from logs, legacy code, or copy-paste—and outputs clean, readable statements with configurable indent size and optional uppercase keywords (SELECT, FROM, WHERE, etc.). All formatting runs in your browser; your queries are never sent to a server, so you can safely format sensitive or proprietary SQL. Ideal for developers, DBAs, and anyone who works with database queries daily.

Frequently Asked Questions
Is my SQL sent to a server?
No. Formatting runs entirely in your browser. Your queries never leave your device.
Does it support all SQL dialects?
The formatter handles standard SELECT, INSERT, UPDATE, DELETE, and common clauses. Very dialect-specific syntax may not be perfectly structured but will remain intact.
Can I format multiple statements at once?
Yes. Paste multiple statements separated by semicolons; the formatter will process them and output formatted SQL.
