An ODT file is an OpenDocument text document that can be created using word processing applications such as Apache OpenOffice Writer and LibreOffice Writer. It is a file format for word processing documents, spreadsheets, presentations, and graphics that uses ZIP-compressed XML files. ODT files are similar to file formats created using Word, such as DOCX and DOC, and contain formatted text, images, links, and page information used for document creation and printing. ODT files are part of the Open Document Format (ODF) standard, also known as OpenDocument, which is an open file format specification for office applications. Other ODF file extensions include OpenDocument Sheets (ODS) for spreadsheets and OpenDocument Presentations (ODP) for slideshows. ODT files are widely compatible with other office suites and are relatively easy to convert back and forth to different file types. To open an ODT file, one can use office applications with native ODF compatibility such as Apache OpenOffice Writer and LibreOffice Writer. Microsoft Word can also open ODT files and save them in other formats such as DOC and DOCX.
