ODF, or Open Document Format, is a file format used for electronic documents. It is an open standard, meaning that it is publicly available and can be used by anyone without restrictions. ODF is designed to be used with office applications, allowing users to create, edit, and share documents like text files, spreadsheets, and presentations. The format is widely supported by various software programs, including LibreOffice and Apache OpenOffice. ODF files typically have extensions like .odt for text documents, .ods for spreadsheets, and .odp for presentations. This standard promotes interoperability between different software applications, ensuring that documents can be accessed and edited across different platforms.
