Taxonomy

Hi,
First of all thanks for making this great plugin.
I would like to add a taxonomy to my website, I don’t know if your plugin is supporting this.
I am trying to use a very simple CSV file and I keep getting the message that the file is not a CSV file.

Here is a link to the file I am trying to use to add Taxonomy:

Thanks for your help and efforts,
Eli.
