Also covers: UPPERCASE · lowercase · Title Case · Sentence case · camelCase · PascalCase · snake_case · kebab-case
The result appears here as you type.
Paste a sentence, a headline, or a whole list. Each line is converted separately, so a list of field names stays a list.
UPPERCASE, lowercase, Title Case, and Sentence case for writing; camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and dot.case for code. The result updates instantly as you switch.
Copy or download the result, or use it as the input for another conversion.
Title Case capitalizes the major words and keeps short words like "a", "of", and "the" lowercase unless they come first ("The Lord of the Rings"), the style used for headlines and book titles. Sentence case capitalizes only the first word of each sentence and the pronoun "I", like normal prose.
No. Words that already contain capitals are left as they are, so "APIs in .NET" stays correct. The exception is text written entirely in capitals: it's lowercased first so it can be title-cased properly.
The text is split into words at spaces, punctuation, and existing case changes, then rejoined in the target style. So "customer order id", "customerOrderId", and "customer-order-id" all become customer_order_id in snake_case. Characters that can't appear in identifiers are dropped.
No. The conversion runs in your browser, and nothing is uploaded.
Text & code
Compare two texts or code files side by side, with changed words highlighted. Ignore whitespace or case, and export a unified .diff patch that git apply accepts.
Count
Count words, characters, sentences, paragraphs, and lines as you type, with reading and speaking time. Check text against X, SEO title, and meta description limits.
Cleanup
Clean up messy text: remove extra spaces, blank lines, invisible characters, and HTML tags, straighten quotes, and rejoin hard-wrapped lines.
Lines
Delete repeated lines from a list and keep the original order. Choose case sensitivity, whether to ignore surrounding spaces, and whether to keep the first or last copy.
Lines
Delete blank lines from text, or collapse runs of blank lines down to one so paragraphs stay separated.
Whitespace
Collapse repeated spaces into one, trim spaces from the start and end of lines, or remove every space. Line breaks are kept.
