What is a case converter?
This tool rewrites your text in a different letter case — from everyday formats like UPPERCASE, lowercase, Sentence case and Title Case to the identifier styles programmers live in: camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case and path/case. Multi-line input is converted line by line, so lists and code snippets keep their structure.
Common uses
- Developers renaming variables, constants, file paths and CSS classes between conventions.
- Writers and editors fixing headlines to Title Case or normalizing SHOUTING TEXT.
- Data cleanup — normalizing inconsistent labels in spreadsheets before import.
How to use it
- Paste your text into the input box.
- Pick a target case from the dropdown — the result appears instantly.
- Copy the result or download it as a text file.
Title Case follows editorial style: small words like a, of, the stay lowercase unless they start or end the line.

Conversion runs entirely in your browser — nothing is uploaded.
