I was a bug. I have solved it.
Open each metatag and save it again.
You will see the name of store in the second column of the list of metatags.

I'll use this separator |

Template Product can import only one picture.
But you gave me a good idea. I'll add support several pictures.

If you need to import several pictures you can use template Product Pictures

Download the new release and try it.

Do you want to add new product Tags or update Product Tag Mapping (add tags to products)?

Yes.
Write me after 3 days.

This is Product data specification for Google feed for Retail.
You can create the feed file in  .csv, .tsv, .xls, or xlsx file.
Open Feed Manager and open menu Feeds.
You will see the button "Add New" at the top right place.
You can create
Google XML - XML feed file
Google Adwords (TSV) - the same feed file in tsv format (with TAB separator).

tsv file is like csv file.
tsv file has tab a separator.
csv file has comma a separator.

Feed Manager allows to creatr any custom feed templates too.
Read this [url=/documentation-nopfeedmanager#q10]topic[/url].

Use the template for import "product specifications values"

Use this csv file

Id,sa,sao,displayOrder,ShowOnHomePage
43,Color,Blue,5,TRUE
43,Color,Red2,5,TRUE
43,Color,Red,5,1

Id,sa,sao
43,Color,Blue
43,Color,Red2
43,Color,Red

Yes.
This is simple Google feed file.
It's the same template.

You can use static default values for category/product (the third tab).
But I see only one solution - create external Feed Manager Plugin
See our documentation
If you need I'll this plugin myself.
It will cost 60$.
I think it's a easy way.
