The ability to export invalid zones is available in the new MyGeotab version. You should see this option under the Import Zones section.
When uploading the zones in an excel file, you do not need any headers for the columns, as the system will start making the zones from row A of excel. Other than that, please make sure you do not add any formatting in the file.
At this time, we offer both options for customer ease. However, if the zone shape and size are defined under the excel file, they will take priority over the options in the zone importer.
These options are included so they can be set by the customer, again for customer ease. These may be added as options into the excel file in the future.
Currently we allow .shp files to import zones through the Geotab SDK. These other file options may be included in the future
