Managing an online store with a large inventory can be overwhelming, especially when adding products manually. For each item, you have to upload an image, create attributes and variations, set the price and shipping class, and a lot more.
This is where the WooCommerce bulk product upload feature comes in handy. Instead of entering product details one by one, you can upload hundreds or even thousands of products simultaneously using a structured CSV file.
This means less time spent on data entry and more time focusing on growing your business. It also helps improve efficiency and accuracy when uploading products, as the process is less cumbersome, and you’re not in a rush to get things done.
In this post, we’ll take a closer look at importing products in WooCommerce using the bulk upload feature. We’ll show you how to prepare your product data and provide a step-by-step guide to uploading your items.
Before proceeding with a bulk upload, it’s essential to understand the key product data fields required for a successful import.
Each product entry should include the following details:
Having accurate and well-structured data is critical for maintaining a well-organized store. Pricing errors can lead to financial losses, while the wrong inventory could cause you to run out of stock unexpectedly or be left with unsold units.
Plus, if product details are missing or they aren’t clear, your conversion rates are going to suffer as shoppers lose confidence.
Note that if you sell digital items, some of the above data, like shipping class and stock quantity, will not apply to you.
Now, let’s look at some essential preparations for importing products in bulk.
There are several options for bulk uploading products in WooCommerce.
By default, WooCommerce includes a CSV importer that allows you to import a file with all essential product details. You won’t need to install a plugin, and it’s a pretty straightforward option.
However, there are extensions you can use if you’re looking for additional features.
For example, Product CSV Import Suite for WooCommerce lets you import custom data for your products. This includes appointment availability and assigned professionals (for courses, spa treatments, etc), as well as details about product vendors and brands (ideal if you run a marketplace or multi-vendor store).
There’s also Import Export Suite for WooCommerce, which offers support for various product types, including subscriptions and grouped items. It also imports coupons, orders, and reviews.
The WP All Import extension has a drag-and-drop interface for bulk product uploads. Besides the essential details listed above, it includes SEO metadata, image galleries, and custom fields. It even lets you set up scheduled imports, which is useful if you need to regularly update your product data.
So, choose a method (or extension) that best suits your needs. If you sell standard products, without any specific or advanced attributes, the default bulk upload functionality should be enough.
Next, you’ll need a template to help you structure your data. If you’re using an extension, it will likely provide its own template.
Alternatively, you can download the sample_products.csv file from GitHub. If you’d rather create your own template, make sure it follows the correct schema formatting.
Now that you have your template, you can customize it to align with your needs.
If there are columns that do not apply to you, go ahead and remove them. If you’re adding new ones, ensure that the headers are clear and formatted correctly.
Also, check that you’ve included all required fields, like product names and SKUs.
This next step can be a little taxing, but you should only need to do it once.
Gather all the necessary product details. Unless you produce everything yourself, you’ll likely need to gather some data from suppliers and manufacturers. This includes information about materials (or ingredients), sizes and dimensions, and usage instructions.
When you enter your data, make sure it’s formatted correctly. For example, prices need to be in decimal format (like 25.99), and dates should be formatted as 2025-06-07.
Once you’re done, check the file for any errors. It’s important not to rush through this step, as any inconsistencies or missing information could result in additional work, like re-uploading everything.
This part will require some work as well. However, if you do things right, you won’t need to manually upload photos to every product.
First, upload all your product images to the Media Library in WordPress.
Alternatively, you can upload them to a third-party platform that supports publicly-accessible image URLs. Avoid using cloud storage links that require authentication.
Then, grab the image URLs and add them to your CSV file in the following format:
https://example.com/image1.jpg
Remember to add each link to the corresponding product. You can add more than one image URL per product, and the first one will automatically be set as the featured image.
You’re now ready to bulk upload your products.
In your WordPress dashboard, go to Products -> All Products and click on Import. Choose the CSV file that contains your product data and select Continue.
Next, you’ll see the Column Mapping screen. WooCommerce automatically matches the column name on the left to the corresponding product field in your CSV file.
Go through the list to make sure everything looks good. You can use the dropdown menus to adjust the fields or instruct WooCommerce not to import that data.
When you’re ready, click the Run the importer button. WooCommerce will now import your products.
Wait for it to finish, then return to Products → All Products to see your imported items. Check that all your products are there, and review each one to make sure that the information is correct.
As you can see, there’s not much work involved in the actual import process. You just need to ensure that you have all the essential data in place before you upload your CSV file.
Uploading variable products requires additional steps.
First, identify the parent product. In the Type column, make sure the product is set to variable.
Then, add a new row for each variation. Set the type to variation for these rows, and give each variation a unique name and SKU.
For example, if your variable product is a hoodie, your variations might be the same hoodie but in red, blue, or green. Here’s how you might list them in your CSV file:
| 78 | variable | woo-hoodie | Hoodie |
| 79 | variation | woo-hoodie-red | Hoodie – Red |
| 80 | variation | woo-hoodie-green | Hoodie – Green |
| 81 | variation | woo-hoodie-blue | Hoodie – Blue |
Now, add four new columns and give them the following labels:
Under the Attribute 1 name column, specify the attribute (e.g., color or size). Write this down for every product with the color attribute.
Under Attribute 1 value(s), specify the color (e.g, red, blue, green) or the size (e.g., S, M, L)
Enter 1 in the Attribute 1 visible column. This marks the attribute as visible.
You’ll also need to enter 0 in the Attribute 1 global column. This marks it as a custom attribute that’s applied to that product only.
To add another attribute, just follow the steps above but use another numerical value for the labels, such as:
Remember to edit details like price and stock availability for each variation (if needed). For example, your red hoodie might cost more than the green version.
Image handling can be one of the trickiest parts of a bulk upload in WooCommerce. If not done correctly, your products will be missing photos.
First, you’ll need to upload images to the Media Library or an accessible external source. Once uploaded, fetch the URL of each image and add it to the corresponding product row under the Images column.
If you’ve uploaded your photos to the Media Library, the URLs will look something like this:
Alternatively, you can use the filename instead of the URL. Here’s an example:
To find this information, go to Media → Library, click on the image you want, and locate the file name on the right:
If you scroll down, you’ll also find the file URL.
You can add multiple image URLs and file names for the same product. Just make sure to separate them with commas, as shown in the example below:
Note that you can’t import alt text or enter it into the CSV file. You’ll need to manually add it to your images in WordPress.
The WooCommerce bulk import tool is also useful for updating existing products.
Let’s say you want to change the prices of all products in your store. In this case, you would make your changes in the CSV file and re-upload it.
Make sure to tick the checkbox for Update Existing Products, as shown below:
In the column mapping section, you can select Do not import for the fields that are staying the same.
If you already have products in WooCommerce but they’re not saved in a CSV file, you can export them. To do this, go to Products -> All Products and click on Export.
Select the columns, product types, and categories that you want to save.
When the download is complete, open the file and edit as needed. Then, re-upload it to WooCommerce.
If you have a lot of work to do, it’s easy to overlook some essential things. So, here are a few tips to ensure your bulk upload goes smoothly.
First, use a template rather than create your CSV file from scratch. As mentioned earlier, you can download a template with sample data from GitHub.
It’s also a good idea to do a small test first. Populate the template with data for five or ten products, then import the file to make sure there are no errors with the columns and formatting.
You could even import the completed file to a staging site. You’ll be able to check all the product data in a safe environment and prevent customers from coming across inaccurate information. Once you’ve confirmed that everything’s good, go ahead and push your changes live.
If you’re worried about breaking your website, make a backup before uploading your products. It’s also smart to perform a backup after the upload, so you won’t have to re-import everything if something happens to your site.
Finally, refer to the official WooCommerce documentation for troubleshooting bulk upload issues.
Bulk uploading products in WooCommerce is an efficient way to manage your store’s inventory. It works by creating a CSV file that contains all the necessary product data and importing it into your online store. With this feature, you’re also able to bulk update existing products on your store.
If you want to import custom data fields, like coupons, reviews, and product vendors, you can use an extension like Product CSV Import Suite and Import Export Suite. Just make sure to back up your website before and after importing your products to prevent data loss.
