Import / Export metafields, upload data through CSV

Shopify Discussion

Topic summary

Users are frustrated that Shopify’s native metafield feature lacks built-in bulk import/export functionality via CSV, forcing merchants to either purchase third-party apps or manually enter data.

Key Pain Points:

  • Bulk editor doesn’t support pasting data, making manual entry impractical for large SKU counts
  • Native CSV import can delete existing metafield data when using “overwrite” option
  • Variant-level metafields (like GTIN/UPC) don’t appear in product exports

Workarounds & Solutions:

  • As of 2024, native metafield export/import is possible by including metafield columns in CSV format: Metafield:namespace.key [type]
  • Third-party apps like Matrixify ($20/month for 5,000 items) and DataChamp (limited free plan) offer bulk management
  • Manual entry remains viable for smaller catalogs

Critical Technical Requirements:

  • List-type metafields require line breaks (\n), not commas
  • Column names must exactly match format: Metafield:namespace.key [type]
  • Data types must be precise (e.g., list.single_line_text_field)
  • Standard spreadsheet apps (Excel, Numbers) corrupt line breaks; Python scripts or text editors recommended
  • Predefined list values must match exactly (case-sensitive, no spaces)

Merchants report typical monthly costs of $125-200 including necessary apps, far exceeding base subscription pricing.

I was also able to convert tags to metafields using Shopify Flow, however I’m having trouble with single line text lists. For some reason I can’t add multiple values from a metafield list without overwriting one or the other.

Would anyone be able to help?
