SQL Formatter & Beautifier

SQL formatting adds consistent indentation, line breaks, and keyword casing to a query without changing its intended structure. It makes joins, predicates, subqueries, and selected columns easier to review in a pull request or incident trace. Formatting is not optimization and it cannot prove a query is safe. Dialects differ, so the formatter's selected language should match the database engine that will execute the statement.

Use a redacted query when the text contains customer values, credentials, or internal identifiers, and confirm that formatting preserves quoted identifiers and literal strings. Review parameterization separately: a pretty query can still be vulnerable to injection or an accidental full-table update. Run the formatted statement through the database parser, explain plan, and permission checks before using it in production. Keep a migration or query test as the authoritative artifact.

SQL often contains schema names and operational context that should not be uploaded to a third-party beautifier. Local formatting keeps the source in the current session and returns instantly, which is useful during review or an outage. The privacy benefit does not make the query harmless; redact secrets, avoid executing copied statements blindly, and verify the target database, transaction boundary, and rollback path before running anything.
