Preparing your product data for import

Success starts with properly formatted data. Here's how to prepare:

Key formatting rules:

Step-by-step import process

  2. Download sample CSV to see correct format
  3. Prepare your file following the template
  4. Upload your CSV (max 15MB)
  5. Review import preview for errors
  6. Confirm import and monitor progress

Pros: Simple, free, built-in
Cons: Limited features, no automation

    headers: {
      'Content-Type': 'application/json',
      'X-Shopify-Access-Token': accessToken

};

Advanced import strategies

Importing from multiple suppliers

Managing diverse supplier formats:

  • Create mapping templates per supplier
  • Standardise naming conventions
  • Merge duplicate products
  • Handle different pricing structures

Example with MeldEagle:

  • Supplier A uses XML with wholesale prices
  • Supplier B provides CSV with RRP
  • Supplier C has API with real-time stock
  • All automatically imported with consistent formatting

Handling complex product data

Image Src,Image Position,Image Alt Text
https://example.com/image1.jpg,1,Front view of blue t-shirt
https://example.com/image2.jpg,2,Back view of blue t-shirt

  • Use namespace and key structure
  • Import custom specifications
  • Add technical details
  • Include care instructions

  • Auto-assign based on product type
  • Use tags for smart collections
  • Map supplier categories
  • Create seasonal groupings

Price calculations during import

Instead of manual markup:

Supplier Cost: £10.00

Your Rule: Cost × 2.5 + £2

Selling Price: £27.00 (automatically calculated)

Advanced pricing rules:

  • Tiered markup by price range
  • Category-specific margins
  • Competitor price matching
  • Currency conversion

Common import errors and solutions

Error: "Invalid CSV file format"

Solution:

  • Check UTF-8 encoding
  • Verify comma separation
  • Remove special characters
  • Ensure proper line breaks
Error: "Duplicate handle"

Solution:

  • Make handles unique
  • Add SKU to handle
  • Use auto-generation rules
  • Check for trailing spaces
Error: "Image could not be downloaded"

Solution:

  • Verify image URLs are public
  • Check image format (JPG, PNG)
  • Ensure URLs use HTTPS
  • Test links before import
Error: "Variant limit exceeded"

Solution:

  • Shopify limits: 100 variants per product
  • Split into multiple products
  • Use product options wisely
  • Consider bundling apps

Best practices for successful imports

1. Start small
  • Test with 10-20 products first
  • Verify all fields imported correctly
  • Check front-end display
  • Refine before full import
2. Maintain data quality

  • Inventory synchronisation?
4. Back up before major imports
  • Export existing products
  • Document current settings
  • Save original import files
  • Enable version control

  5. Scale gradually: Increase automation as you grow

Whether you're importing 10 products or 10,000, the key is choosing the right method for your needs.
