Case converter
Free text case converter online: camelCase, CONSTANT_CASE, Title Case, Unicode-aware.
Overview
Clean up names, constants, or pasted prose with one click. Title case is Unicode letter aware. Identifier helpers split on spaces, hyphens, underscores, and camel-case boundaries so you can refactor labels without reaching for an editor macro. Output updates in a dedicated pane so your source text stays intact until you copy.
Title and sentence modes use Unicode-aware rules. Identifier modes split on spaces, hyphens, and underscores; camel and Pascal also split on aA boundaries. Pick a style—the output follows your typing.
Frequently asked questions
How does sentence case conversion work in this text case converter?
The string is lowercased, the first letter is capitalized, and letters after ., !, or ? are capitalized following whitespace.
Does title case work with accented letters and non-English text?
Yes. Word detection uses Unicode letters (`\p{L}`) so accented characters are preserved and capitalized correctly.
Can I convert multi-line text to camelCase, snake_case, or title case?
Yes. The whole textarea is transformed; line breaks remain unless a specific mode removes them elsewhere.
