How it works

The tool tokenises your input by splitting on spaces, underscores, hyphens, and camelCase boundaries, then rebuilds the words in the target case format. Everything runs in JavaScript inside your browser tab.

Processing runs in your browser

All conversion happens using the browser's built-in JavaScript engine. Our servers are not involved at any point.

For swapping substrings across pasted text, try find and replace. To alphabetise or dedupe lines after converting, use sort lines. For checking length after a case change, see the word counter.

Frequently asked questions

Does it keep punctuation and spaces?

Is this useful for code?

Does it work with non-English letters?
Yes. The tool uses JavaScript's toUpperCase() which handles Latin, Greek, Cyrillic, and most other scripts that have a defined uppercase form.
