BigCommerce Bulk Custom Fields Import

Add or update custom fields across your BigCommerce catalog from a file. File2Cart maps CSV or Excel columns to product or variant custom fields and imports in bulk—so you can power filters, storefront logic, and integrations without manual data entry.

Who This Is For

Merchants and developers who use custom fields for attributes, filters, or app data. If you need to set or update custom fields for many products or variants and have that data in a spreadsheet, bulk custom fields import is built for you.

What You Get

  • Map columns to custom fields—field names and values from your file
  • Target products or variants by ID, SKU, or barcode
  • Support for common value types—text, number, list, etc.
  • Validation and preview so you don't overwrite data by mistake

How It Works

Structure your file with one row per product or variant and columns for each custom field. Upload to File2Cart, map to the right field definitions, validate, and run the import.
