About this tool

SQL Case Converter is a free online tool that rewrites SQL keywords between UPPERCASE and lowercase while leaving string literals, numbers, and quoted identifiers untouched. Bring a consistently-cased query style to any codebase in one click.

Modes: Keywords → UPPERCASE, or keywords → lowercase
Preserved: String literals, numbers, comments, and quoted identifiers are never modified
Input: Pasted SQL text
Output: Re-cased SQL, ready to copy
Signup: Not required
Processing: Entirely in your browser — pasted SQL is never uploaded
Difference: Re-cases keywords only — string literals, numbers, and quoted identifiers are never touched
Price: Free, no usage limits

Limitations

Keyword recognition is pattern-based — a small number of dialect-specific keywords may be left as-is
The tool changes keyword casing only; it does not rename tables or columns
