SQL Formatter

The SQL Formatter tool cleans up and standardizes SQL statements to enhance readability and maintainability. It accepts raw SQL and outputs a consistently formatted version that aligns keywords, breaks long lines, and standardizes indentation. The primary users are developers, DBAs, data engineers, and analysts who work with SQL in code, documentation, or migration scripts. The formatter preserves the original semantics while applying a uniform style.
Conceptually, the tool analyzes tokens, classifies them as keywords, identifiers, literals, operators, and punctuation, then rebuilds the statement with a defined structure. It prioritizes readability by placing each clause on its own line, capitalizing reserved words, and aligning logical blocks. It also respects comments and string literals to avoid altering their content. The result is easier review, diffing in version control, and safer handoffs to teammates.
Core value and use cases: standardizing SQL across a codebase, preparing scripts for deployment, improving diffs in pull requests, and teaching consistent SQL style to junior developers. Core features include keyword capitalization, consistent indentation, proper semicolon termination, support for common subqueries and joins, and optional dialect presets. Users benefit from faster reviews, fewer formatting disputes, and higher code quality without changing query logic.
