Running a BigCommerce store, whether you are adding products in-house, third-party team, or with the help of AI, it is important to understand how to upload products to a BigCommerce store without messy listings and wrong prices.
To upload products to BigCommerce, log in to your store admin, go to Products → Add, and fill in the product name, price, description, images, and inventory details, then click Save & Publish. That's the fastest way to get a single product live. If you have multiple products to upload at once, go to Products → Import, download BigCommerce's CSV template, fill it in with your product details, and upload the file. BigCommerce will process it and add all your products in one go. Both methods work. It just depends on whether you are adding one product or many.
For a store with only 50 or 100 products, follow the step-by-step guide with detailed print screen shot here at How to Add Products in BigCommerce: simply copy and paste, fill product information, save, and repeat to add products quickly. It is a very easy process.
But most BigCommerce shoppers ignore the basic product import guidelines, trusting others even during migration, resulting in wasted time and disappointment after a big loss. This guide walks you through exactly how to upload products to BigCommerce, via CSV for bulk uploads in simple language with detailed print shot examples that any store owner can follow, no tech background needed.
What You Need Before You Start
1. A BigCommerce store with Products access
Login into admin and check the products import section permission is ok or not
2. Product images hosted online
BigCommerce does not allow you to upload images from your computer via CSV. Every image must have a live, publicly accessible URL, i.e., hosted on BigCommerce's own servers, Google Drive (public sharing), Dropbox, or any image hosting service.
3. Organize your import template
Populate product names, SKUs, prices, descriptions, weights, and category names without errors or messy in the CSV template.
4. Google Sheets or Microsoft Excel
Google Sheets is recommended. Excel sometimes adds extra characters when saving to CSV format, especially when there are special characters in descriptions.
How to Bulk Upload Products in BigCommerce Using the Import process?
Bulk uploading products in BigCommerce means adding or updating multiple products using a CSV file, instead of creating each product manually.
Let us check How to Prepare Your CSV File for BigCommerce
Step 1: Prepare Your CSV File
The safest way to start is to export your existing products and use that file as your template.
- Log in to your BigCommerce admin panel
- Go to Products → Export
- Select the Bulk Edit template
- Choose CSV file format and click Export Products
- Open the downloaded file
If your store has no products, BigCommerce provides a downloadable template directly on the Import screen.
Step 2: Understand the Required Columns
Your CSV upload must include specific column headers for the import to work. Here are the most important things we should care about:
| Column Header | What It Is | Required? |
|---|---|---|
| Product Name | Full product name as it appears in your store | Yes |
| Product Code/SKU | Unique identifier for the product | Yes |
| Price | Retail selling price | Yes |
| Item Type | "Product" for standard items | Yes |
| Category | Full category path (e.g. Clothing/Men/Shirts) | Recommended |
| Product Description | Full description text | Recommended |
| Product Weight | Weight for shipping calculations | Recommended |
| Brand Name | Manufacturer or brand | Optional |
| Track Inventory | Y or N | Optional |
| Image File 1 | Full URL of the main product image | Recommended |
Important
Column headers are case-sensitive. Leave the Product ID column blank for new products. BigCommerce assigns IDs automatically. For the Category column, use the full path with forward slash: Electronics/Phones/Accessories
Step-by-Step: How to Upload Your CSV File in BigCommerce
Step 1 - Go to Products → Import
Log in to your BigCommerce admin panel. In the left-hand navigation, click Products, then click Import.
Step 2 - Upload Your CSV File
Click Choose File and select your CSV from your computer.
Step 3 - Select Your Import Settings
Make sure the following checkboxes are selected before importing your CSV file:
File was exported using the 'Bulk Edit' template, tick if you used the exported template
Overwrite existing products, tick if you want to update products already in your store
Ignore blank values. Tick if you only want to update specific fields and leave the rest unchanged Overwrite existing products
Step 4 - Map Your Import Fields
BigCommerce shows a preview screen called Link Import Fields. This matches your CSV column headers to the correct store fields.
After confirming the field mappings, click Next.
Step 5 — Start the Import
Click Start Import.
- Then, click Start Import to begin importing your products into BigCommerce.
- A pop-up window on the same page will display the import progress. Do not close the browser tab while the import is running.
- You can monitor your import status here and wait for it to complete.
Step 6 - Review the Import Summary
After the import process runs, BigCommerce will display a summary. This summary shows the number of products successfully imported and highlights any errors that need correction.
- A green text box means the import was successful.
- A yellow warning indicates that some products were imported but with issues (e.g., a missing image URL).
Always check this summary carefully. The error messages provided will tell you exactly which rows had problems and why. This is crucial for fixing errors.
Common Errors in CSV Import and How to Fix Them
- Image URL is not valid: The image URL in your CSV is broken, Open every image URL in a browser tab. If it loads, it works. If not, upload new image and update the URL.
- SKU already exists: You are trying to import a product with an SKU that is already used in your store. Ensure all SKUs in your import file are unique or that you intend to update an existing product.
- Required field is missing: A required column (usually Product Name or SKU) is blank for one or more rows. Check your CSV for missing values before importing.
- Category does not exist: BigCommerce automatically creates a new category if the name in your CSV doesn't match an existing one. A typo like 'Electronnics' instead of 'Electronics' creates a new category. Therefore, always spell-check category which very important.
- Incorrect Column Headers: Column names in your CSV don't match BigCommerce's required format. Always use the exported template as your starting point. Never use the old copy.
- File size too large: CSV file exceeds BigCommerce upload size limits i.e. 20MB file upload limit.
Pro Tips for a Smooth Bulk Upload
Always Back Up First: Export your current products before a large import.
Test with 5 products first: Before importing 2,000 products, try importing 5. This helps you verify your CSV format is correct.
Use "Update Existing Products": When you need to update prices or inventory, you can import a CSV with just the Product ID, SKU and the field you want to change (e.g., price). In the import screen, select the option to Update Existing Products.
Keep Your CSV File Clean: Avoid formulas, merged cells, or extra formatting in your spreadsheet. Plain data is best.
Use High-Quality Data: For a well-organized catalog, double-check that your product names and options are clear and correct.
