You can export tags fields only by custom export field selector (Bullet Points, search tags, used for, target audience) You can edit and upload the fields back into StoreAutomator.
Here are the steps:
1- Select the products and go to Export>Custom…
2- Select the fields from the Tags section.
3- Download the file from the “Notifications” from the top right.
These are the fields in the file.
IMPORTANT NOTE: When you are entering your data into the related fields, please fill the empty cells within the order. (First Bulletpoint 1, then Bulletpoint_2). The same logic is also valid for other tags(used_for_1, then used_for_2). Otherwise, you are likely to get an error when you upload the file into SA.
IMPORTANT NOTE: If you want to delete a specific field data, you must leave the cells as empty. This action will delete the data which you have already in SA, when you upload the file back into SA.
4- After the changes, upload the file back into SA.
