Create new variants

Create new variants in bulk in two ways:

Add values to an existing option

Products have Size with S and M, and you want to add L and XL.

1. Select the products
2. Configure Bulk Edit, choose Create new variants
3. Pick the option (like Size) and type the new values, comma separated: L, XL
4. Preview, then Apply

Each product receives only the values it is missing. Products that already have a value keep it; nothing is duplicated. This means you can safely run the same job over a mixed catalog, or re-run it later to finish a collection.

Create a whole new option

Products only have Size, and you want to add a Color or Finish option.

1. Select the products
2. Choose Create new variants, then Create a new option
3. Type the option name and its values, for example Finish: Textured, Smooth
4. Preview, then Apply

What happens to existing variants: they receive the first value you listed (Shopify requires every variant to have a value for every option). Each additional value creates a new variant per existing combination. A product with 5 sizes gains 5 new variants when you add a second value.

Safety defaults for new variants

• Price is copied from the product’s existing variants
• Inventory starts at 0, so nothing can be sold before you stock it
• SKU is left blank, so no duplicate SKUs are created
• Gift card products are skipped automatically
• Shopify allows at most 3 options per product; products already at 3 are skipped and reported

After the job: set stock

When a create job finishes, the app offers to set a starting quantity on all the new variants at once: type a quantity, pick a location, one click. See Set stock on new variants.
