# Overview How to access on Fynd Commerce Commerce Panel → Products → My products → Bulk Action → Import ## Introduction In the earlier sections, you have learnt to [create a single product](/commerce/docs/products/catalogue/creating-product) as well as [bulk products](/commerce/docs/products/catalogue/importing-catalogue). Now, what if you wish to update the attributes (e.g. material, colour, weight, etc) of one or more products? Manually editing the products and changing their attributes is clearly not the solution. Therefore, Fynd Commerce has an option of **Partial Update**. You can upload an Excel or CSV file containing the product details along with the new attribute values. ## At a Glance **Primary Identifier-related Attributes**: * **Prices**: Actual Price, Selling Price, Currency * **Volumetric Data**: Length, Width, Height, Weight * **Identifier Data**: GTIN Type, GTIN Value How are these identifier-level attributes? In e-commerce, each size has a unique product identifier. Different sizes of a product may carry different price tags. Similarly, different sizes of a product may need different packaging. Since all these attribute data depend on the product’s size, the attributes can be partially updated on the platform by including the column **`Seller Identifier`**. **Product-related Attributes**: * **Appearance**: Colour, Primary Colour, Pattern, Material, Primary Material * **Customs**: HSN Code, Country of Origin * **Information**: Description, Short Description, Highlights...and many more How are these not identifier-level attributes? In e-commerce, each size has a unique product identifier. No matter what the size of the product is, attributes such as colour, material, or description still remain the same. Since these attributes do not depend on the product’s size, the attributes can be partially updated on the platform by including columns **`Item Code`** and **`Brand`**. Include all 3 columns, i.e. **`Item Code`** , **`Brand`**, and **`Seller Identifier`** while updating the data of both, primary identifier-related attributes and product-related attributes in a file. Attention While creating a catalogue of set products, for a given size group, you have to repeat the primary identifier in all the cells of `Seller Identifier`column. You need not repeat the size group in the `Size Group` column (check the below snapshot). ![QG11](https://cdn.pixelbin.io/v2/doc/original/searchlight/platform-panel/products/partial/set-seller-identifier.png) (In the older versions, for a given size group, primary identifier was not repeated but size group had to be repeated)
