Common questions
How do I convert uppercase text to lowercase or sentence case?
Paste the text and copy the lowercase card, or the Sentence case card if you want capitals at the start of each sentence. Sentence case also capitalizes the start of each line, the word I, days, months and common acronyms such as USA. It cannot guess other names, so add them, for example Priya or NASA, to Always write these words as typed.
Does Sentence case keep my punctuation and line breaks?
Yes. Sentence case and Capitalized Case only change letters, so commas, full stops, quotes and line breaks stay exactly where they were. A new sentence starts after a full stop, question mark or exclamation mark followed by a space, and after every line break.
What is the difference between Capitalized Case and title case?
Capitalized Case gives every word a capital, including a, of and the. Title Case keeps those small words lowercase unless they come first or last, and the card here follows AP rules. Use the Title Case Converter for APA, Chicago, MLA and other style guides.
What separates snake_case from kebab-case?
Only the joining character. snake_case uses underscores and is common for Python variables and database columns. kebab-case uses hyphens and is common in URLs and CSS class names.
Why does camelCase remove punctuation from my text?
The code cases split your text wherever there is a character that is not a letter or digit, then rejoin the words with their own rules. Apostrophes, commas and full stops are dropped because identifiers cannot contain them. Each line is converted on its own, so a list of ten names gives ten identifiers.
What are alternating case and inverse case used for?
Alternating case flips between lower and upper letter by letter and is mostly used for jokes and memes. Inverse case swaps the case of every letter, which fixes text typed with caps lock on by accident: hELLO wORLD becomes Hello World.
Does the case converter change numbers or symbols?
No. UPPERCASE, lowercase, Sentence case and Capitalized Case only change letters. Order #42-B becomes order #42-b in lowercase, with everything else left alone.
Can the case converter handle accented or non-English letters?
Yes for scripts that have upper and lower case, such as accented Latin, Greek and Cyrillic, so élan becomes ÉLAN. Scripts without case, such as Hindi or Urdu, pass through unchanged.
How do I stop the case converter lowercasing brand names?
Type the names in Always write these words as typed, separated by commas or new lines, for example iPhone, WordPress, New Delhi. Sentence case, Title Case and Capitalized Case then use your spelling wherever the word appears. UPPERCASE, lowercase and the code cases ignore the list on purpose.
