About Case Converter

The QuickToolz Case Converter switches text between every common letter case used in writing, programming, and data work. Convert UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and dot.case with one click.

Why developers and writers love it

  • Writers: fix all-caps shouting in pasted quotes, capitalize headlines correctly

  • Developers: convert variable names between Python (snake_case), JavaScript (camelCase), CSS (kebab-case), and constants

  • Data engineers: normalize column names from spreadsheets

  • Editors: apply consistent title case to headings across a document

Smart title casing

Title Case follows standard English rules: capitalize all major words; leave articles, conjunctions, and short prepositions lowercase unless they’re the first or last word.
