Runs in your browser. Your entries are calculated on this device. Ziannah does not store the values you enter here.
Each conversion has its own page, with examples and answers for that format.
Paste your text, pick a format, and copy the result. This is a letter case converter, so only the letters change: numbers, spaces, and punctuation come back exactly as you pasted them. Here is what each format does.
For a heading or a title, use Title Case, or Sentence case if your style guide prefers it. To fix a line someone typed with caps lock on, use Sentence case. To tidy data for a spreadsheet or a set of file names, use lower case so everything matches.
Paste the text that is in capitals into the box above. Choose Lowercase to make every letter small, or choose Sentence case to make it read like an ordinary sentence again. Press Copy, and the fixed text is ready to paste back where you need it.
Paste your text, choose Title, and the first letter of each main word is capitalized. Then press Copy to take the result with you.
Title Case capitalizes the main words, which suits headings. Sentence case capitalizes only the first letter of the sentence, which is how normal writing looks.
Title Case keeps small joining words like of, the, and and in lowercase, so it reads as a proper title. Capitalize Each Word puts a capital on every word without exception.
Paste the capitalized text and choose Lowercase to make every letter small, or Sentence case to read like an ordinary sentence again.
