How to add a new product with multiple sizes via the import tool
Key features
- Create a single new product with the Insert/Create New mode
- Create a product with multiple sizes with the Insert/Update mode
- The first row creates the product; subsequent rows add items (sizes)
Single product
Use the Insert/Create New import mode to create a single product. This mode creates new products where the ID does not exist, regardless of the name, and does not update existing products.
Product with multiple sizes
Use the Insert/Update import mode. This mode creates a product if no matching ID or Name exists, and updates an existing product if there is a match.
How it works:
- The first row creates the product with its Name and assigns an ID.
- Subsequent rows match the Name from the first row to add additional product items (for example, sizes).
Example
The import file below creates a product named Black Shoe with an auto-generated ID and Article Number 40331. Two sizes (S and M) are added, each with its own unique article number.
