OpenDocument Text file
The Open Document Format (ODF) is an XML-based open source file format for saving and exchanging text, spreadsheets, charts, and presentations. Files saved under ODF, termed "OpenDocuments," have easily recognizable extensions, similar to Microsoft's proprietary .doc or .xls. The most commonly encountered extensions include:
- .odt for word processing files
- .ods for spreadsheets
- .odp for presentations
- .odg for graphics
- .odf for formulas or other mathematical equations.
