XLS - MS Excel format
Driver short name
This driver reads spreadsheets in MS Excel format. GDAL/OGR must be built against the FreeXL library (GPL/LPL/MPL licensed), and the driver has the same restrictions as the FreeXL library itself as far as which and how Excel files are supported. (At the time of writing - with FreeXL 1.0.0a -, it means in particular that formulas are not supported.)
Each sheet is presented as a OGR layer. No geometry support is available directly (but you may use the OGR VRT capabilities for that).
OGR_XLS_HEADERS = FORCE / DISABLE / AUTO : By default, the driver will read the first lines of each sheet to detect if the first line might be the name of columns. If set to FORCE, the driver will consider the first line will be taken as the header line. If set to DISABLE, it will be considered as the first feature. Otherwise auto-detection will occur.
OGR_XLS_FIELD_TYPES = STRING / AUTO : By default, the driver will try to detect the data type of fields. If set to STRING, all fields will be of String type.
