—About Case Converter
The Case Converter transforms text between sentence, title, upper, lower, camel, pascal, snake, and kebab case with a single click. It serves developers renaming identifiers and writers fixing capitalisation in bulk.
Re-casing text by hand is tedious and error-prone. Converting it locally is instant, handles programming conventions correctly, and keeps your text off any server.
Step by step
- Type or paste the text you want to re-case.
- Pick the target case — for example Title Case for headings or snake_case for identifiers.
- The converted text appears immediately.
- Copy the result, or download it if you converted a large block.
What it offers
- Multiple case transformations
- One-click conversion
- Sentence, title, and more
- Processed locally
Tips for best results
- Use snake_case or kebab-case for identifiers that must avoid capital letters, such as file names or CSS classes.
- Title case here follows common conventions; review proper nouns and acronyms afterward.
- Convert in batches by pasting a whole list rather than one line at a time.
