Product Modifier Import/Export
Product modifiers are used to adjust the price on a given sku. For example if you are selling a mug that has an option for adding custom text. The sku will remain constant but having it engraved will affect the price.
You can adjust the price, shipping and weight.

To access the modifier import/export feature, in the admin you will go to: Store Catalog > Import/Export Tools > Product Modifier Importer
The following examples show the import spreadsheet format. All of the column headers listed will be required. The modifier type (Drop Down List/Image Radio Button List/Radio Button List) is what will determine which option you select to use.
