XML File Formats

By default, LibreOffice loads and saves files in the OpenDocument file format.

OpenDocument file format names

LibreOffice uses the following file formats:

Document format	File extension
OpenDocument Text	*.odt
OpenDocument Text Template	*.ott
OpenDocument Master Document	*.odm
HTML Document	*.html
HTML Document Template	*.oth
OpenDocument Spreadsheet	*.ods
OpenDocument Spreadsheet Template	*.ots
OpenDocument Drawing	*.odg
OpenDocument Drawing Template	*.otg
OpenDocument Presentation	*.odp
OpenDocument Presentation Template	*.otp
OpenDocument Formula	*.odf
OpenDocument Database	*.odb
LibreOffice Extensions	*.oxt

ODF Chart is the name of the file format for stand alone charts. This format with the extension *.odc is currently not in use.

Evolution of the OpenDocument format

The OpenDocument format evolves over time.

ODF version	Date of standard approval by OASIS	First supporting version of the software
ODF 1.0	2005-05-01	OpenOffice.org 1.1.5 or StarOffice 7
ODF 1.1	2007-02-02	OpenOffice.org 2.2 or StarOffice 8 Update 4
ODF 1.2	2011-09-30	OpenOffice.org 3, StarOffice 9, Oracle Open Office
ODF 1.2 (Extended)	-	OpenOffice.org 3.2 or StarOffice 9.2

In current versions, you can select to save your documents using ODF 1.2 (default) or ODF 1.0/1.1 (for backward compatibility). Choose Tools - Options - Load/Save - General and select the ODF format version.

If you want to exchange documents with users that still use older versions of LibreOffice, save the document in the following formats:

XML file structure

Documents in OpenDocument file format are stored as compressed zip archives that contain XML files. To view these XML files, you can open the OpenDocument file with an unzip program. The following files and directories are contained within the OpenDocument files:

1. The text content of the document is located in \<emph\>content.xml\</emph\>.

   By default, content.xml is stored without formatting elements like indentation or line breaks to minimize the time for saving and opening the document. The use of indentations and line breaks can be activated in the Expert configuration by setting the property /org.openoffice.Office.Common/Save/Document PrettyPrinting to true.

2. The file \<emph\>meta.xml\</emph\> contains the meta information of the document, which you can enter under \<emph\>File - Properties\</emph\>.

   If you save a document with a password, \<emph\>meta.xml\</emph\> will not be encrypted.

3. The file \<emph\>settings.xml\</emph\> contains further information about the settings for this document.

4. In styles.xml, you find the styles applied to the document that can be seen in the Styles window.

5. The \<emph\>meta-inf/manifest.xml\</emph\> file describes the structure of the XML file.

Additional files and folders can be contained in the packed file format.
