About this tool
Case conversion comes up more than you'd think. You need snake_case for a database column, camelCase for a JavaScript variable, or UPPER CASE for a constant. Instead of manually retyping everything, paste your text here and pick the format you need. It converts as you type, so you can try different formats and grab the one that works.
Converts as you type, no submit button needed
Supports UPPER, lower, Title, camelCase, and snake_case
Handles multi-line text and mixed input
One-click copy to clipboard
Quick reference table to compare all formats
