Common mistakes
- Using Title Case expecting it to skip short words like 'a', 'the', or 'of', as in English editorial style.This tool capitalizes the first letter of every word with no exceptions, so articles and prepositions get capitalized too.
- Converting text to camelCase or snake_case expecting existing symbols like parentheses, commas, or hyphens to be preserved.Any character that isn't a letter or number is treated as a separator between words and dropped from the result, not kept as a symbol.
- Applying 'Sentence case' to a text with acronyms or proper nouns in the middle, expecting them to keep their capitalization.'Sentence case' lowercases the entire text before capitalizing the start of each sentence, so acronyms and proper nouns in the middle lose their capitalization and need to be fixed by hand.
Frequently asked questions
camelCase starts with a lowercase letter and each following word starts with a capital (myVariable). PascalCase does the same but the first word is also capitalized (MyVariable). snake_case separates words with a lowercase underscore (my_variable). kebab-case separates them with a hyphen (my-variable), commonly used in URLs.
Accented letters are kept as part of the detected words; only spaces and punctuation between words are used as separators, not the accented letters themselves.
It converts the entire text to lowercase and then capitalizes the first letter of each sentence — that is, the first letter of the text and the first letter after a period, question mark, or exclamation point.
No. The format conversion happens entirely in your browser using JavaScript, without sending the text to any external server.
Alternatives
VS Code has built-in text transformation commands (uppercase, lowercase), and libraries like lodash (camelCase, snakeCase) do the same within code. This tool is handy for converting a one-off text without installing any library or opening the editor.
