“jean-luc picard” — Uppercase, Lowercase, Title Case and Sentence Case
Enter this string in the converter and these are the four outputs it returns. Nothing here is stored or guessed: the same regular expressions that run in your browser were run at build time, so the page and the tool agree character for character.

How the rules behave on this string
Every conversion starts from the same tidy-up: runs of spaces collapse to one and the ends are trimmed, while line breaks are preserved. Uppercase and lowercase then apply directly. Sentence case lowercases everything and re-capitalises the first letter after a full stop, question mark, exclamation mark or line break. Title case lowercases everything and re-capitalises the letter that follows the start of a line, a space, a quote, a bracket or an apostrophe.
The hyphen counts as a word boundary in this implementation, so 1 hyphen in the input produce 1 extra capital in Title Case. That matches the converter exactly; copy editors differ on whether the second half of a compound should be capitalised.
The four outputs differ only in where the capitals land, but the raw counts stay fixed: 13 letters, 5 vowels (38% of the letters), 2 non-letters and 2 words packed into 15 characters. Upper and lower case are exact inverses here — the 2 capitals that Title Case produces would become 13 under UPPERCASE and zero under lowercase. At position 73 among 76 strings in the reference, it averages 6.5 letters per word with “jean-luc” the outlier at 8.

Frequently asked questions
What does each of the four results mean?
They are four separate passes over the same 15-character string. UPPERCASE and lowercase are the obvious ones. Title Case capitalises the first letter of every word, and Sentence case capitalises only the first letter of each sentence while forcing everything else down. The converter on the homepage builds them with the identical rules.
Which one should I paste into my document?
For interface strings, Sentence case is the safer default: it reads like a sentence, translates more cleanly and avoids the question of which words count as important enough to capitalise.
