What is an ODT file?

An ODT file is a text document created by various word processing programs, such as the Writer program included in Apache OpenOffice and LibreOffice. It contains formatted text and may also include images, drawn objects, and tables. ODT files are similar to .DOCX files.

Apache OpenOffice is a free, open source alternative to Microsoft Office. To save money yet still produce Office-compatible documents, some students and professionals use OpenOffice in place of Microsoft Office.

Writer is OpenOffice's equivalent to Microsoft Word. It allows users to write and format personal and business documents, such as resumes, letters, essays, and research papers. Writer saves users' documents in ODT files, which are similar to Word's DOCX files.

ODT files are formatted using the OASIS XML-based OpenDocument standard. This standard is used by OpenOffice, LibreOffice, and other variants, all of which save documents as ODT files.

NOTE: Apache OpenOffice was formerly known as OpenOffice.org.

How do I open an ODT file?

You can open an ODT file in a variety of word processors, including:

In all of those programs, you can also convert your ODT file to a DOCX file. Note that you may lose some formatting when you open an ODT file in a program other than OpenOffice or LibreOffice or convert an ODT file to another format.
