Do you have to upload one file per type

like product service

[ogletree]

I have different types of things to put in Google products. Do I need to make a new file for every type of products? Each product might have different attributes. Or do I just put them all in the same file and leave the ones blank that I don't use?

You can use XML file type to upload your products
And Each product have different attributes is ok
