Document editors are software applications that allow users to create, edit, and format text documents. They provide various tools for writing, such as spell check, grammar check, and text formatting options like bold, italics, and bullet points. Popular examples of document editors include Microsoft Word, Google Docs, and LibreOffice Writer. These editors often support collaboration features, enabling multiple users to work on the same document simultaneously. They can also save files in different formats, such as PDF or DOCX, making it easy to share and distribute documents. Document editors are widely used in both personal and professional settings.
