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.

Ok guys, looks like we are many having the same issue, and have resolved to manually entering meta fields, SO HERE IS A WARNING!!!

I just did a bulk upload of my products after making some changes, and I chose ‘overwrite existing products’. However, turns out that by doing this, ALL MY META DATA GOT DELETED!!!

For me, I was using meta data for warehouse location. So I now have 3 warehouses with a few thousand SKUs, and I have no idea where to find each product :disappointed_face:

In case anyone knows about a roll back option, please le me know. And don’t make the same mistake, as these meta fields are so fragile when we have no way of doing backups…
