// CASE CONVERTER · ABOUT THIS TOOL
About the Case Converter
Rewriting text into a different case by hand is slow and error prone, especially for long headlines, product names or code identifiers. This case converter does the job instantly in your browser: UPPERCASE, Title Case, Sentence case, and camelCase, snake_case or kebab-case variable names.
Each style follows the real rules of its convention, word and character counts update as you type, and everything runs locally on your device so your text stays completely private.
Where it helps most
Thirty-second fixes across writing and code.
Fix spreadsheet exports
Somebody exports a spreadsheet column in ALL CAPS, so convert it to readable case with one click instead of retyping.
Repair client headlines
A client returns your headline written entirely in lowercase, so restore it to proper Title Case the traditional way.
Name variables instantly
A developer copies a label with spaces and needs it as a variable name; convert it in one click, ready for source code.
Format prose correctly
Title Case capitalizes principal words the way headlines are traditionally set, while Sentence case matches ordinary prose exactly.
Converting cleanly
What is preserved, and what changes.
Paragraphs preserved
For the standard prose styles, your paragraphs, line breaks and spacing stay preserved exactly as you typed them.
Code styles join
Programming styles like camelCase, snake_case and kebab-case intentionally join everything into single words, exactly as naming conventions demand.
Live counts included
The page keeps a live word and character count as you type, and finishes with Copy and Download buttons for the result.
Case Converter: private by design
Everything runs locally in your browser. Nothing is uploaded and nothing is stored, so drafts and code snippets never leave your machine.
