Text Case Converter — Standard & Programming Casing, One Tool

Paste text to convert it to every common case style at once — UPPERCASE, lowercase, Title Case, Sentence case, plus programming-specific cases like camelCase, PascalCase, snake_case and kebab-case — rather than a single-case converter you have to re-run for each variant you need.

How to use Text Case Converter

  1. Paste your text.
  2. See it converted to every case style simultaneously.
  3. Copy the one you need.

Frequently asked questions

Does it handle converting between programming cases correctly?
Yes — converting camelCase to snake_case (and similar) correctly splits on case boundaries rather than just lowercasing everything and losing the word boundaries.
What is the difference between Title Case and Sentence case?
Title Case capitalizes most words ("This Is A Title"); Sentence case capitalizes only the first word ("This is a sentence") — both are shown so you can pick what your context needs.
Does it work on multi-line text?
Yes — each line is converted independently, preserving your line breaks.
