How People Use BigCommerce → Shopify
A client wanted to move from BigCommerce to Shopify Plus before Black Friday. We had 8,500 products with 15 images each — that's 127,000+ image rows to restructure. The tool handled the column-to-row conversion perfectly and the Shopify import accepted the file on the first try.
My BigCommerce store used sale prices on most products. When I tried a manual CSV import to Shopify, the Compare At Price field was blank and strikethrough pricing disappeared. This tool mapped Sale Price to Variant Price and original Price to Compare At — exactly what Shopify needed.
BigCommerce → Shopify Migration Questions
What BigCommerce export format should I use?
Use the standard BigCommerce Products export (Products → Export). Make sure to export all fields including images, pricing, and inventory.
How are multiple product images handled?
BigCommerce exports images in columns (Product Image URL - 1 through 15). We create a separate Shopify row for each image with the same Handle, properly numbered by position.
Is this a one-time migration or ongoing sync?
This is a one-time export/import converter. For ongoing sync, you'd need a Shopify app with API access.
Why BigCommerce Products Don't Import Directly to Shopify
The CSV Structure Mismatch
BigCommerce exports store image URLs in 15 separate columns (Product Image URL - 1 through 15).
Shopify requires each image as a separate row with the same Handle identifier.
BigCommerce uses different field names, weight units, and category structures than Shopify.
Direct import fails with missing column errors or imports incomplete data.
What This Tool Does
We restructure your BigCommerce export:
- Images: 15 columns → separate Shopify rows
- Fields: BigCommerce → Shopify column names
- Weights: Ounces/pounds → grams
- Handles: Names → URL-safe slugs
- Prices: Sale Price → Variant + Compare At
- Categories → Shopify tags
- Inventory → Shopify policies
Shopify import succeeds with complete data.

Frequently Asked Questions
You can, but free scripts and AI often miss edge cases that break real-world data: missing SKUs, currency formatting quirks, tax calculation errors, or date format mismatches. We have battle-tested validators specifically designed for accounting software imports that catch these issues before they corrupt your books. Plus, you get instant browser-based conversion without installing Python or managing dependencies.
Use the standard BigCommerce Products export (Products → Export). Make sure to export all fields including images, pricing, and inventory.
BigCommerce exports images in columns (Product Image URL - 1 through 15). We create a separate Shopify row for each image with the same Handle, properly numbered by position.
This tool handles base products. For variants, you'll need to export BigCommerce product options separately or configure them in Shopify after product import.
We generate Shopify handles from product names (e.g., 'Classic T-Shirt' → 'classic-t-shirt'). Use the 'bc-' prefix option to avoid conflicts. Set up 301 redirects in Shopify for SEO preservation.
Stock levels are migrated to Shopify's Variant Inventory Qty field. Inventory tracking is automatically enabled for products with stock data.
BigCommerce categories are converted to Shopify tags. You'll need to manually create Shopify Collections and set up automated collection rules using these tags.
If a Sale Price exists and is lower than the regular Price, we set Variant Price = Sale Price and Compare At Price = regular Price. This shows strikethrough pricing in Shopify.
BigCommerce SEO fields aren't in the standard product export. You'll need to export them separately or reconfigure in Shopify after import.
This is a one-time export/import converter. For ongoing sync, you'd need a Shopify app with API access.
This tool migrates products only. For customers and order history, you'll need separate migration tools or Shopify migration apps.
