Frequently asked questions
Which case conversions are on this page?
All six live on this one URL: title case, sentence case, UPPER CASE, lowercase, camelCase, and snake_case. There are no standalone pages for a title case converter, sentence case converter, camel case converter, or snake case converter. Converted text is shown for every mode at once.
How does title case work on this page?
Title case here is simple first-letter-of-word. The page splits on whitespace, uppercases the first letter of each token, and lowercases the rest. It is not AP or Chicago title case and does not keep small words such as of or the lowercase.
How does sentence case work?
The text is lowercased, then the first letter of the string is uppercased. The first letter after a period, exclamation mark, or question mark plus a space is also uppercased. That is a simple sentence split, not a grammar parser.
How do camelCase and snake_case work?
camelCase splits on whitespace, underscores, and hyphens, lowercases the first word, capitalizes later words, and joins them with no separator. snake_case splits on whitespace, hyphens, and camel boundaries (a lowercase or digit followed by an uppercase letter), lowercases the pieces, and joins them with underscores.
Is my text uploaded? Do I need an account?
No. Conversion runs in your browser. Text is not uploaded. There is no signup, and Tallymill does not save what you paste. Refreshing the page clears the form.
Is there a size limit?
Yes. Input larger than 100KB (100 × 1024 UTF-8 bytes) is rejected. Empty input is valid and returns empty strings. Nothing is sent to a server either way.
