A case converter can quickly turn all-caps notes into readable copy or standardize a list of headings. Choose the intended style first, then apply it to a sample before changing the whole document.
Review acronyms, brand names, names, identifiers, and text in languages with special casing rules. Automatic title case may capitalize small words oddly; lowercasing an identifier can change its meaning. Keep the original for comparison when exact spelling matters.
The tool saves typing, but it cannot decide which letters are semantically important.
