About This Tool

The tool accepts raw SQL text and returns a formatted version tailored to a target dialect. It preserves comments and string literals, ensuring no semantic changes while improving readability. It is designed for development, database administration, data engineering, and teams that enforce coding standards across projects.
Conceptually, it tokenizes input, builds an internal representation, and re-emits SQL with standardized indentation, clause-aligned line breaks, and controlled wrapping of long lines. It supports ANSI SQL baseline and applies dialect-specific rules for quoting, keyword casing, and statement termination. This makes scripts easier to review, merge, and maintain in version control.
Beneficiaries include developers, DBAs, data engineers, and data teams who want consistent styling across projects. Unique value comes from dialect-aware defaults, robust handling of nested subqueries and common table expressions, preservation of comments, and the ability to save and reuse style profiles across sessions and projects.

Frequently Asked Questions

Find Quick Answers

Which dialects are supported?

The formatter supports ANSI SQL baseline with dialect-specific rules for MySQL, PostgreSQL, MSSQL, Oracle, and SQLite, allowing proper keyword casing and quoting.

Will it change query semantics?

No. Formatting only reflows and standardizes layout; it preserves all literals, identifiers, and comments, ensuring behavior remains identical.

Can I save and reuse style profiles?

Yes. Advanced settings can be saved as profiles and reused across sessions or pipelines to maintain consistent formatting rules and defaults.

What happens on parsing errors?

If the SQL cannot be parsed, the tool returns the input with a formatting hint and no changes to semantics; unparseable sections remain as originally written.
