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

What is snake_case?
snake_case joins words with underscores in lowercase: 'Hello World' becomes 'hello_world'.
Can it convert from camelCase?
Yes. It splits on camelCase boundaries as well as spaces and hyphens before lowercasing and joining with underscores.
Is this useful for databases?
Yes. Most SQL column naming conventions and Python variable names use snake_case.
Is my text sent to a server?
All processing runs in your browser using JavaScript. Our servers are not involved at any point.
