Fix text typed with Caps Lock on
Worked out in your browser. No sign-up.
Paste your text and choose a style: sentence case, all lower case, ALL CAPS, or a capital at the start of every word. It's mostly used to rescue something typed with Caps Lock on. Serbian letters work too: lj, nj and dž change correctly, so “LJUBAV” becomes “Ljubav”, not “LJubav”.
How it works
“Sentence case” first makes everything lower case, then puts a capital at the start of the text, after a full stop, question mark or exclamation mark, and at the start of each new line. Names in the middle of a sentence, such as London or Marko, stay lower case, so fix those by hand.
“Title Case” capitalises every word, including short ones like “of” and “the”. Most English style guides keep those lower case, so check a headline before you use it.
In Serbian, lj, nj and dž are single letters. At the start of a word only the first part is a capital (Ljubljana, Njegoš), while a word in full capitals gets both: LJUBLJANA.
Worked example
A notice in your building arrives as “TOMORROW FROM 9 TO 13 THERE WILL BE NO WATER IN ENTRANCE 2.” After “Sentence case” it reads “Tomorrow from 9 to 13 there will be no water in entrance 2.”
A list of names, “ljiljana đorđević, john smith”, becomes “Ljiljana Đorđević, John Smith” with “Title Case”.
Questions people ask
Should every word in a title start with a capital?
In British English most newspapers and the GOV.UK style guide use sentence case for headings. Title Case is more common in American publishing. Serbian never capitalises every word in a title.
How do I change capitals to lower case in Word?
Select the text and press Shift + F3. Each press switches between lower case, upper case and capitalised words.
Does it work with Cyrillic?
Yes, Cyrillic text changes case in the same way. To switch Serbian between Latin and Cyrillic, use the Latin to Cyrillic converter.
