What is an ODT file?
An ODT file is a text document saved in the OpenDocument Text (ODT) format, which is primarily used by the LibreOffice Writer and Apache OpenOffice Writer word processors. It contains formatted text and may include images, tables, charts, and drawn objects. ODT files are an open alternative to Microsoft Word's .DOCX format and commonly save resumes, research papers, essays, reports, and other text-based documents.
More Information
OASIS (Organization for the Advancement of Structured Information Standards) released the ODT format in 2005 as part of the OpenDocument Format (ODF) 1.0 specification. The organization developed ODT to provide an open, XML-based alternative to proprietary document formats like Microsoft Word's .DOC and DOCX.
Since its release, the ODF standard has undergone several updates, with the latest version being ODF 1.3, published in 2021. The ODT format remains widely used in LibreOffice Writer and Apache OpenOffice Writer among users (often students) who prefer free, open-source software over commercial alternatives like Microsoft Word.
Technical Details
ODT files conform to the OpenDocument standard maintained by the Organization for the Advancement of Structured Information Standards (OASIS). They are ZIP-compressed archives that contain XML-based document structure and content files, along with embedded media and style information.
How to open an ODT file
You can open ODT files with various word processors, including:
If you open an ODT file with a program other than LibreOffice Writer or OpenOffice Writer, it may lose some formatting.
How to convert an ODT file
Various word processing applications, including LibreOffice Writer, Microsoft Word, and Corel WordPerfect, can convert ODT files to other formats.

An ODT file may also be a data file created by OOMMF (Object Oriented Micromagnetic Framework), a micromagnetics analysis package developed by the National Institute of Standards and Technology. It contains one or more tables of micromagnetics data saved as ASCII plain text. ODT files usually also contain tags and comments that describe the data they contain.
More Information
OOMMF is a public domain micromagnetics package that allows physicists to solve micromagnetics problems. When a physicist solves a micromagnetics problem, OOMMF produces an ODT file that contains tabular text data. Each table includes:
- The solver iteration count
- Nominal applied field
- Reduced average magnetization
- Total energy
Each ODT file begins with the line # ODT 1.0, to identify it as an ODT file. In addition to tabular data, ODT files may also contain the following tags:
- Table Start: Used to segment a file containing multiple data tables
- Title: Used to specify a table's title
- Units: Used to specify data's units of measurement
- Table End: Paired with a corresponding Table Start tag
ODT files may also contain comments, preceded by ##.
How to open an ODT file
You can open an ODT file in OOMMF (multiplatform). Doing so will visually display the data the file contains. You can also open an ODT file in any text editor, to view the data it contains as plain text.
