About String to camelCase conversion

camelCase is the standard naming convention for variables and functions in JavaScript, Java, Swift, and many other languages. This tool handles every common input format — including strings that are already partially camelCase or PascalCase — so you never need to manually reformat identifiers.

This string to camelCase converter splits input on whitespace, hyphens, underscores, and uppercase letter transitions, then joins the resulting words with the first word fully lowercased and each subsequent word capitalized. It correctly handles PascalCase, SCREAMING_SNAKE_CASE, kebab-case, and plain sentences. Process multiple strings at once with one camelCase result per input line, all locally in your browser.

Smart splitting

Splits on spaces, hyphens, underscores, and case transitions — no matter the input format.

  • Handles PascalCase input

camelCase conversion tips

Get clean, consistent camelCase output every time.

  • Remove leading/trailing whitespace from your input before pasting to avoid unexpected word boundaries.
  • Use one line per identifier when batch-converting — the tool maps output 1-to-1 with input lines.
  • Digits within a word pass through unchanged; check that numeric segments land in the position you expect.

Frequently asked questions

How does this handle already-camelCase input like 'myVariableName'?>
The converter detects transitions from a lowercase letter or digit to an uppercase letter and splits there. So 'myVariableName' becomes the words 'my', 'Variable', 'Name' and is reassembled as 'myVariableName' — the same result, correctly re-cased.
What happens to consecutive delimiters like double hyphens or double underscores?>
Consecutive delimiters collapse into a single word boundary. 'a--b' and 'a__b' both produce just two words, so no empty segments appear in the output.
Can I convert SCREAMING_SNAKE_CASE variable names to camelCase?>
Yes. Underscores are treated as word boundaries, and each word is fully lowercased before recapitalization. 'MAX_RETRY_COUNT' becomes 'maxRetryCount'.
Does the tool skip blank lines in my input?>
No — blank lines are preserved. A blank input line always produces a blank output line, so your line count stays the same and you can safely paste multi-line lists without losing position.
