Case Converter
A case converter rewrites text into a different letter-casing style without changing the words themselves. Toolverge supports the nine most-searched styles, from plain UPPERCASE/lowercase to developer conventions like camelCase and snake_case, and it understands camelCase input well enough to split it back into words before re-casing.
How it works
- Paste or type your text.
- Pick a target case from the dropdown.
- Copy the converted result — it updates as you type.
Formula Split on word boundaries (camelCase humps, `_`, `-`, spaces), then re-join per target case rule.
Frequently asked questions
Does this handle camelCase or snake_case input?
Yes. Input is split at lower-to-upper letter transitions and at underscores/hyphens before being re-joined in the target case, so "helloWorld" converts cleanly to "hello_world" or "Hello World".
What does Sentence case do with multiple sentences?
It capitalizes the first letter after the start of the text and after each ".", "!", or "?" followed by a space.
What's the difference between camelCase and PascalCase?
camelCase lowercases the first word ("helloWorld"); PascalCase capitalizes every word including the first ("HelloWorld").
Is my text uploaded anywhere?
No. Conversion runs entirely in your browser.
Does Title Case skip small words like "a" or "the"?
No — every word is capitalized. Style guides differ on which small words to skip, so Toolverge keeps the simple, unambiguous rule.
