ODT stands for Open Document Text, which is a file format used for word processing documents. It is part of the Open Document Format (ODF) standard, allowing users to create, edit, and share text documents across different software applications. ODT files are commonly used in programs like LibreOffice and Apache OpenOffice. The ODT format is based on XML, making it both human-readable and machine-readable. This means that users can easily access and modify the content of the files using various text editors. ODT supports features like text formatting, images, and tables, making it versatile for various document types.
