Usage
Features
Beautify, minify, and syntax-highlight common SQL statements such as SELECT, INSERT, UPDATE, DELETE, and CREATE. Switch between multiple indentation styles and keyword case conventions to keep a consistent SQL style across database consoles, code reviews, and docs.
Steps
Choose indentation and keyword case in "Format Settings"; paste or type the original SQL into the "SQL Input" box (or click "Sample" to load a demo); click "Beautify" to wrap and indent by main keywords, or "Minify" to collapse the SQL into a single compact line; the result is shown with syntax highlighting, and you can click "Copy" at any time.
Benefits
Readability: line-wrapped and indented SQL is easier to understand, helping code review and collaboration; Debugging: a clear structure helps locate syntax errors and logic issues quickly; Maintenance: consistently styled SQL is easier to maintain over time; Learning: formatting helps beginners grasp the hierarchy and order of SQL clauses.
Notes
This tool uses a keyword-based simplified parser that may not fully recognize complex syntax such as stored procedures, CTEs, or window functions. Highlighting injects inline styles into HTML, but copying yields plain text. Minify mode strips comments and extra whitespace, so use caution with SQL containing sensitive comments. Keyword sets vary slightly across database dialects; adjust manually for unrecognized keywords.
