Type something to see all ten conversions at once.
How it works
Case and naming styles
Type or paste some text and you see all ten conversions at once: UPPER CASE, lower case, Title Case, Sentence case and the code naming styles camelCase, PascalCase, snake_case, CONSTANT_CASE, kebab-case and dot.case. Each one has its own copy button.
For code styles, text is split into words at spaces, hyphens, underscores and lower-to-upper case changes, keeping acronyms together: XMLHttpRequest becomes xml_http_request. If you paste several lines, each one is converted on its own, so you can rename a list of fields in one go.
Lines and counts
The Lines tab sorts (A-Z, Z-A or natural, where file2 comes before file10), reverses the order, removes duplicate and empty lines, trims spaces and adds numbers. Options combine and the result updates right away. At the top you always see the count of characters, words, lines and UTF-8 bytes, handy for length limits in databases or forms.
