Converting single products to variations will require you to use a product CSV file. If you are not familiar with this file, we recommend downloading a sample product file, so that you can see how products look in a spreadsheet. You can do this by navigating to Settings > Export Data > Products > Template Only.

In the example below, you will see a group of single SKUs that need to be converted into variations. To do this, you just need to follow a few easy steps.

Insert a row above the SKUs you want to group together, then add your parent SKU in the "sku" column (column A). 

Then add that same parent SKU in the "parent_sku" column (column B). Make sure that your parent SKU is only in the rows next to your product SKUs. As pictured below, cell B4 does not contain a parent SKU.

NOTE: Before moving on, remember to add required product information such as "name" and basic information like "description", "price", etc.

Next, you need to assign variation attributes to your products, which will tell Sellbrite what your product varies on.

Scroll to right of your spreadsheet until you reach your the "variation_1" column.
In the new parent row that you've added, insert the product's variation attributes (size, color, etc.)

Lastly, you need to add variation values for each one of your products. If the variation attribute is "Color", then each value would something like "Blue", "Green", "Red", etc. Make sure that each variation value is in the correct row, so that sizes and colors are assigned to the right SKU.

Once you're done, all you need to do is re-import your file back into Sellbrite by navigate to Settings > Import Data > Products > CSV File.
