What does this tool do?
Case Converter transforms your text between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, kebab-case and more in a single click. It saves writers, students and developers from retyping a mistyped heading or hand-editing variable names one character at a time.
How to use it
- Paste your text into the input area.
- Adjust the options to fit your needs.
- Copy the processed text.
Which formats are supported?
The tool covers every common transformation: UPPERCASE and lowercase, Title Case that capitalizes each word, Sentence case that capitalizes only the first letter, camelCase (firstWordLower), PascalCase, underscore-separated snake_case, hyphenated kebab-case, and the playful aLtErNaTiNg case where letters flip between upper and lower. A copy button puts the result straight onto your clipboard so you can paste it wherever you need.
Real-world use cases
Fixing a paragraph typed with Caps Lock on without retyping it, making article and assignment titles consistent, cleaning up a messy name list pasted from a spreadsheet, and converting a variable name from snake_case to camelCase when moving code between languages. Everything runs in your browser, so your text never leaves your device.
Frequently asked questions
What is the difference between camelCase and snake_case?
camelCase joins words with no spaces and capitalizes each new word (exampleVariable). snake_case keeps words lowercase and separates them with underscores (example_variable). The first is common in JavaScript, the second in Python.
Does Title Case keep small words like 'and' or 'of' lowercase?
Title Case here capitalizes the first letter of every word. If you follow English style guides that keep short conjunctions and prepositions lowercase, you will need to lowercase those few words manually after converting.
