Convert text to CamelCase

This tool converts text to CamelCase. It provides flexible options so you can convert the entire text into lowerCamelCase, convert it into UpperCamelCase (PascalCase), convert only specified words to CamelCase (leaving other words as they are), or convert all words except those you explicitly allow. Simply enter your text, choose the conversion mode that suits your needs, and process your text.

Processing Modes:

Convert Entire Text to lowerCamelCase
Splits the text into words, converts the first word to lowercase and capitalizes the first letter of each subsequent word, then joins them with no spaces.

Convert Entire Text to UpperCamelCase
Splits the text into words, capitalizes the first letter of every word, and joins them with no spaces.

Convert Only Specified Words to CamelCase
Converts only the words you specify (comma‑separated) to CamelCase (capitalizing the first letter and lowercasing the rest) while leaving other words unchanged.

Convert All Except Allowed Words to CamelCase
Converts every word to CamelCase (capitalizing the first letter and lowercasing the rest) except for those you explicitly allow. Enter a comma‑separated list (e.g., hello, sample).
