The formatter runs SQL through a dialect-aware parser strategy in the sql-formatter engine. It tokenizes query blocks, recognizes dialect-specific keywords, operators, and delimiters, then rebuilds the statement with deterministic spacing, indentation, and normalized keyword casing. Dialect-specific features (for example, T-SQL identifiers, MySQL modifiers, or PostgreSQL casting syntax) are preserved while producing a consistent code style, which reduces review friction and improves long-term maintainability.
