OpenDocument is a file format used for creating and sharing documents, spreadsheets, and presentations. It is an open standard, which means that anyone can use it without needing to pay for licenses. This format is widely supported by various software applications, including LibreOffice and Apache OpenOffice, making it easy for users to collaborate and share their work. One of the main advantages of OpenDocument is its ability to preserve formatting and content across different platforms. This ensures that documents look the same, whether opened on a Windows PC, a Mac, or a Linux system. By using an open format, users can avoid being locked into proprietary software.
