How to Bulk Import WooCommerce Products with ACF Fields in 2025

Running an online store in 2025 requires more than just a standard catalog of products. It requires efficiency, customization, and scalability. For U.S. store owners, especially those selling unique or handmade products, managing a product catalog with custom fields is essential. It may need specific product specifications, such as size charts, material details, warranty information, or other attributes your customers care about. But with thousands of products to manage, doing this manually is time-consuming and prone to errors.

Bulk importing your WooCommerce Products with their related custom fields plays a vital role in those problems. This would save time and make your store accurate and organized. In this guide, we will walk you through bulk import WooCommerce products with Custom Fields (ACF) using a powerful tool: WP Ultimate CSV Importer.

Section 1: Understanding Advanced Custom Fields in WooCommerce

What ACF Does

Advanced Custom Fields (ACF) allows the store owners to add custom fields to their WooCommerce products that go beyond the standard product title, description, price, and image. Custom fields can be used to add any type of data specific to your products, such as:

• Size charts for clothing, shoes, or accessories
• Product dimensions for furniture or other large items
• Warranty information for electronics or appliances
• Material specifications for handmade or artisan goods

These custom fields provide a better user experience and can help increase sales by giving customers the detailed information they need to make informed purchasing decisions.

For store owners, especially those dealing with a diverse range of products, Advanced Custom fields are vital for organizing product data. Whether you’re selling handmade goods, clothing, or electronics, Advanced Custom Fields helps you tailor your product listings to meet your customers’ needs.

Common Import Challenges

Though Advanced Custom Fields is incredibly helpful, it also has some complexities when it comes to bulk product import. Manual entry of custom fields can be overwhelming and lead to inconsistent or missing information. Imagine the hassle of entering detailed size charts or warranty information for hundreds or even thousands of products one by one. This method is time-consuming and leads to inconsistent and inaccurate data..

Luckily, you don’t have to rely on manual data entry. There’s a much more efficient way to handle this: bulk importing products with custom fields using a CSV file.

Section 2: Step-by-Step Import Process

Now that you understand the importance of ACF fields for WooCommerce products, let’s dive into the bulk import process. With WP Ultimate CSV Importer, you can easily import thousands of products along with their custom fields in a matter of minutes. Here’s a step-by-step guide to help you through the process.

Step 1: Preparing Your CSV for Advanced Custom Fields

The first step is preparing a CSV file that includes all the data you need for your products, including ACF fields. Here’s what you need to do:

1. Create Your CSV Template: Start by creating a spreadsheet with all the necessary columns. The basic columns for a WooCommerce product CSV usually include:
   • Product name
   • SKU (Stock Keeping Unit)
   • Price
   • Description
   • Categories
   • Tags
2. In addition to the default WooCommerce product data, you will need to add custom columns for your ACF fields. For example, if you’re selling clothing, you might include the following ACF columns:
   • Size Chart (for size specifications)
   • Material (for fabric type)
   • Warranty Information (for electronics)
3. Fill in the Product Data: Once your template is ready, begin populating it with your product information. You can do this manually, or if you already have data from another platform, you can export it and modify the CSV to include your custom fields.
4. Format ACF Fields Correctly: When filling in Advanced Custom Fields, make sure you use the correct field names. For example, if your ACF field for the size chart is named size_chart, make sure the CSV column header matches exactly. This ensures that WP Ultimate CSV Importer will correctly map the data during the import process.

Real Example: Importing U.S. Handmade Goods

Let’s say you run an online store selling handmade jewelry. Each product in your store has specific ACF fields, such as:

• Material: Silver, Gold, Stainless Steel
• Care Instructions: How to clean and maintain the jewelry
• Size Chart: For rings or bracelets

To bulk import this data, you would:

1. Create a CSV with columns for the product name, SKU, price, description, and ACF fields like material, care_instructions, and size_chart.
2. Fill in the information for each product. For example, for a silver bracelet, you’d fill out the material column with “Silver,” the care_instructions column with “Polish with a soft cloth,” and the size_chart with the ring size guide.
3. Import the CSV into WooCommerce using WP Ultimate CSV Importer, mapping the CSV columns to the correct fields in WooCommerce, including ACF fields.
4. Configure the import settings and click on Import.

Once the import is complete, your store will have hundreds of products with fully populated ACF fields, ready for your customers to browse.
