The file is ok, but I think you need to do a find-replace on it.
As you are in France, you have used a comma as your decimal place. However, Tableau is expecting the Geo file to be a csv (comma seperated), with periods as decimal places.
You will need to do two seperate find-and-replace actions:
1) Find-and-replace all commas "," with periods "."
2) Find-and-replace all semi colons ";" with commas ","
Once done, I would advice loading 2 or 3 rows just to make sure it works before loading the full lot, as importing can take a while.
Note: I haven't changed my locale to test this, so it may respond differently
It seems it worked. I didn't have any error message.
And now how I use my personnal geocoding?
You can use it in the following way:
- Connect to a datasource
- Right-click on one of the fields (e.g. PATH)
- Go to "Geographic Role" -> Name of custom geocoding file
- Select the corresponding field (e.g. PATH)
If you then double click on this field, Tableau will create a map in the view. You will need to include additional fields in level of detail (e.g. LIGUE, SIGLE etc) so Tableau can identify which map point you mean
