SQL Formatter

A SQL formatter for Oracle syntax standardizes query layout to improve readability and maintainability. It targets database developers, DBAs, data engineers, and code reviewers who require consistent style across a codebase. Use it when refactoring legacy SQL, enforcing a team style guide, preparing code for reviews, or integrating formatting into CI pipelines.
Conceptually, the formatter tokenizes input, parses Oracle syntax, and reconstructs SQL with deterministic rules. It places line breaks before major clauses (SELECT, FROM, WHERE, GROUP BY, ORDER BY, WITH), applies indentation, and uppercases keywords if configured. It can preserve inline comments and string literals, and it avoids altering data values or semantics.
Value and use cases include reducing noisy diffs, speeding code reviews, and enforcing a team style guide. It scales to large queries, handles complex joins, subqueries, and WITH clauses, and can be wired into build systems to guarantee consistent formatted output before deployment.
Core features include required Oracle-compatible parsing and clause-aware formatting; optional features cover indentation customization, wrap width, keyword casing, comment preservation, and alignment options for JOINs and subqueries. Exclusions: it does not execute SQL or verify runtime correctness; it focuses on layout and readability.
