About Change text case
Use the text case converter to normalize a heading, label, or identifier. You can convert text to camelCase or snake_case from separated words, or apply uppercase, lowercase, and a simple title-case transformation.
How to change text capitalization
- Paste the text to transform.
- Select the target Case style and select Process.
- Review the transformed text and download converted-case.txt.
A practical example
- Input
hello world
- Result
helloWorld
The camelCase example starts from separate words. Existing mixed-case identifiers are not analyzed as a programming-language tokenizer.
Supported input and limitations
- Title Case is a simple capitalization rule, not an editorial style guide with special rules for small words.
- Camel and snake conversion tokenize letter/number groups. They do not reliably split an existing camelCase word or preserve acronyms. Text is limited to 5 MB.

Frequently asked questions
Can I convert a sentence to snake_case?
Yes. Select snake_case; groups of letters and numbers are lowercased and joined with underscores.
Does title case follow a publication style guide?
No. It applies a simple capitalization transform and does not implement AP, Chicago, or another editorial rule set.
