Conversion rules

Case conversion runs locally and does not create a second SEO route.

  • Generate ten results from one input without changing the historical URL.
  • UPPERCASE, lowercase, Title, Sentence, Capitalize and Swap Case preserve line structure.
  • camelCase, PascalCase, snake_case and kebab-case normalize word separators.

Common mistakes

  • Using title case when a code identifier is required.
  • Expecting camelCase to preserve punctuation and spaces.

Best practices

  • Choose letter case for prose and identifier case for code.
  • Review acronyms and proper names after automatic conversion.
