ToolsSoup’s camelCase Converter is a free online tool that rewrites any text in camelCase: it lowercases the first word, capitalizes the first letter of every word after it, and removes the spaces, underscores, and hyphens between them. So “user profile id”, “user_profile_id”, and “User-Profile-Id” all become userProfileId. Paste a label, a column name, or a snake_case or kebab-case identifier, click the button, and you get a clean camelCase string ready to drop into your code. Everything runs in your browser — there are no uploads, no sign-up, and no character limit, and your text never leaves your device.

      

        
What is camelCase?

        
camelCase is a naming style where a phrase is written as a single word with no spaces: the first word is all lowercase and each later word starts with a capital letter, like firstName, totalAmount, or getUserById. The capital letters in the middle look like the humps of a camel, which is where the name comes from. It is the standard convention for variables, function names, and object properties in languages such as JavaScript, Java, and Swift. camelCase differs from PascalCase, which also capitalizes the very first word (FirstName), and from snake_case and kebab-case, which keep everything lowercase and join words with underscores or hyphens instead.

        
      

      

        
How to convert text to camelCase

        
Turning a phrase or identifier into camelCase takes just a few seconds:

        
  1. Type directly into the text box or paste the text you want to convert.
  2. Click Convert to camelCase to join the words and capitalize each one after the first.
  3. Review the camelCase result in the output box on the right.
  4. Click Copy result to copy the camelCase string to your clipboard.

      

      

        
When should you use camelCase?

        
Reach for camelCase whenever you need a code-friendly identifier from a human-readable phrase: naming JavaScript and Java variables, object keys, JSON properties, function and method names, or React props. It is also handy for converting database column names, spreadsheet headers, or design labels into the camelCase that most front-end and back-end style guides expect. Because the converter accepts spaced text, snake_case, kebab-case, and PascalCase as input, it is a quick way to normalize mixed naming into one consistent camelCase style without retyping anything.

Frequently asked questions

        

          
How do I convert text to camelCase?

          
Paste your text into the box and click Convert to camelCase. The tool splits the text into words, lowercases the first one, capitalizes the first letter of each following word, and joins them with no spaces. The camelCase result appears in the output box ready to copy with one click.

        

        

          
What is camelCase?

          
camelCase writes a phrase as one word with no spaces, where the first word is lowercase and every later word starts with a capital letter, such as firstName or getUserData. It is the most common naming style for variables and functions in languages like JavaScript and Java.

        

        

          
What is the difference between camelCase and PascalCase?

          
Both join words with no spaces and capitalize each word, but camelCase keeps the very first word lowercase (userName) while PascalCase capitalizes it too (UserName). camelCase is typically used for variables and properties, and PascalCase for class and type names.

        

        

          
Can it convert snake_case or kebab-case to camelCase?

          
Yes. The converter treats spaces, underscores, and hyphens as word boundaries, so user_profile_id, user-profile-id, and “user profile id” all become userProfileId.

        

        

          
Can I convert several names at once?

          
Yes. Each line is converted on its own, so you can paste a list of labels or identifiers and get one camelCase result per line in a single click.

        

        

          
Is my text private?

          
Absolutely. All conversion happens locally in your browser using JavaScript, so the text you enter is never sent to or stored on any server.
