Simple select
sql = SELECT id, name FROM users WHERE active = 1;indent = 2
Result: SELECT id, name FROM users WHERE active = 1;
SQL Formatter
Turn messy SQL into readable, consistently indented queries. Keywords are uppercased, each major clause goes on its own line, and AND/OR inside WHERE are indented. String literals, quoted identifiers, and comments are never touched, so the output runs exactly like the input. 100% client-side.
Privacy: this tool processes your data entirely in your browser. Nothing you paste or type is sent to the server.
Enter your values and press Calculate — the result appears here.
Worked examples
Join with conditions
sql = SELECT u.name FROM users u LEFT JOIN orders o ON o.user_id = u.id WHERE u.active = 1 AND o.total > 100;indent = 2
Result: SELECT u.name FROM users u LEFT JOIN orders o ON o.user_id = u.id WHERE u.active = 1 AND o.total > 100;
Frequently asked questions
Does formatting change what my query does?
No. Only whitespace and keyword case change — string literals, quoted identifiers, numbers, and comments are left exactly as written, so the formatted SQL is equivalent to the input.
How are strings and comments handled?
Single-quoted strings, double-quoted and backtick identifiers, bracket identifiers, and -- and /* */ comments are recognized and preserved verbatim — nothing inside them is modified.
Is my SQL sent to a server?
No. Formatting runs entirely in your browser, so you can safely format queries containing proprietary schema or data.
