Converted text

How it works

The converter tokenises your text on spaces, underscores and hyphens, then reassembles it in the chosen convention. Title Case capitalises each word; Sentence case capitalises after terminal punctuation; the programmer cases (camel, snake, kebab) join words with the respective separator after lowercasing.

Example

"Hello world-from tool" becomes helloWorldFromTool (camel), hello_world_from_tool (snake) or hello-world-from-tool (kebab) — handy when renaming variables or writing config keys.

Frequently asked questions

Does Title Case skip small words like "of" and "the"?

No — it capitalises every word, which matches most style-agnostic uses. Editorial styles like AP have extra rules.

What happens to numbers and symbols?

They pass through unchanged in the plain cases; in programmer cases symbols act as word separators.

Is there a length limit?

No practical one — conversion is instant even for long documents.

Is my text uploaded?

No — everything converts locally in your browser.
