Frequently Asked Questions
Which SQL dialects are supported?
You can format queries as MySQL, PostgreSQL, SQLite, or SQL Server (T-SQL). The dialect affects how identifiers, operators, and dialect-specific syntax like square-bracket quoting are parsed.
Does formatting change what my query does?
No. Formatting only changes whitespace, line breaks, and keyword casing. The statement semantics, identifiers, and string literals are preserved exactly.
What does minify mode do?
Minify removes SQL comments (both -- line comments and /* block comments */) and collapses all whitespace into single spaces, while leaving quoted strings and identifiers untouched. The result is a compact single-line query.
Are my queries sent to a server?
No. Formatting runs entirely in your browser using the open-source sql-formatter library. Nothing is uploaded, logged, or stored.
Why are keywords uppercased?
Uppercase keywords (SELECT, FROM, WHERE) are a widely followed SQL style convention that makes the query structure easier to scan. SQL keywords are case-insensitive, so this never changes behavior.
