This driver can read, write and update spreadsheets in Open Document Spreadsheet format, used by applications like OpenOffice / LibreOffice / KSpread / etc...
The driver is only available if GDAL/OGR is compiled against the Expat library.
Each sheet is presented as a OGR layer. No geometry support is available directly (but you may use the OGR VRT capabilities for that).
Note 1 : spreadsheets with passwords are not supported.
Note 2 : when updating an existing document, all existing styles, formatting, formulas and other concepts (charts, drawings, macros, ...) not understood by OGR will be lost : the document is re-written from scratch from the OGR data model.
