Open Document Format (ODF) is an open, XML-based file format standard for word processing documents, spreadsheets, charts, and presentations. The specification was originally developed by Sun Microsystems, but has been standardized by the Organization for the Advancement of Structured Information Standards (OASIS). ODF version 1.0 has been standardized as ISO/IEC 26300:2006. ODF is the primary format for the office suite.

File Extensions

The main file extensions for ODF documents are

  • .odt for word processing documents
  • .ods for spreadsheet documents
  • .odp for presentation documents
  • .odb for database documents
  • .odg for graphical documents
  • .odf for mathematical formulae

ODF also supports template files for each type of document. The 'd' in file extension is replaced by a 't' for template files.

File Structure

An ODF document can be as simple as a single XML file. However, this is rarely practical. The standard specifies that an ODF file can also be stored as a collection of several subdocuments. The latter is the most common implementation.
