A viewer opens a file just to read it - no conversion, no editing, no install. It is the quickest way to check an email attachment, a download or an old file when you do not have the right program.
Most viewers read the file directly in your browser, so private documents stay on your device. Many also let you copy the content or export it, for example a CSV from a spreadsheet.
