Overview

To update content for multiple items at once, you can set up a Walmart template to make your updates by attribute or GTIN (Global Trade Identification Number). In this guide, we’ll show you how to set up the template and use each method. 

Update by attribute

Step 1 – Get started

Navigate to your Catalog in Seller Center. Select the Update items button and choose Update with file from the dropdown menu. 

Step 2 – Download and complete the template 

Select the Change any item attribute link and follow the steps to set up your Walmart template. For example, if you want to set up the template on your own, select No and then choose the fulfillment type, product categories and product types you want. When you’re done, select the Build spreadsheet button.

Open the template and enter the SKU, product type and product identifier for each of your items. You can remove the rest of the attributes or update them based on your needs.

Pro tip

If you aren't sure which classification to choose, review our content standards. 

Step 3 – Upload the template  

Navigate back to your Catalog, select the Update items button and choose Update with file. Then use the file browser window to upload the template. When you’re ready, select Submit.

After submitting the template, you can track its status from the Activity feed in Seller Center. Updates may take up to 24 hours. Any data errors that are detected during the updates will require extra processing time.

Notes:

To ensure a high-quality shopping experience, Walmart selects the best content for each item attribute, giving priority to content provided directly by brand owners and their authorized resellers. Because brand owners and authorized resellers have priority, there are times when you won’t be able to decide what content is published on Walmart.com. This means that if you don’t have brand owner privileges, you won’t be able to update some content fields, including blank fields.  



Update by GTIN 

Step 1 – Get started

Navigate to your Catalog page in Seller Center. Select the Update items button and choose Update with GTINs from the dropdown menu.   

Step 2 – Provide GTINs

Enter up to 5,000 GTINs into the GTINs text field, using a comma to separate each value. Then select Download file and an editable template will be available in the Downloads tab on the Activity Feed dashboard. Once you’ve downloaded your pre-populated file, you can make updates in the template as needed.

Pro tip

If you copy and paste multiple GTINs from an Excel template into the field, the commas will automatically appear.  

Notes:

You can only enter GTINs for 10 product types at a time. 

Step 3 – Upload the template 

To upload the template, navigate back to your Catalog in Seller Center, then select the Update items button and choose Update with file. Then use the file browser window to upload the template. When you’re ready, select Submit.

After submitting the template, you can track its status from the Activity feed in Seller Center. Updates may take up to 24 hours. Any data errors that are detected during the updates will require extra processing time.
