How to use Text Case Converter
Text Case Converter — complete guide
Case conversion comes up more often than people expect — fixing text accidentally typed with Caps Lock on, converting a heading to Title Case for a document, or preparing a sentence case version of a line pasted from an all-caps source. Doing this by hand is slow and easy to get wrong, especially with longer text.
Title case and sentence case are the two most commonly confused styles: title case capitalizes most major words (used for headings and titles), while sentence case only capitalizes the first word and proper nouns (used for normal body text).
Once your text is in the right case, Word Counter and Character Counter are useful next steps for checking length limits before you publish or submit it.
