Metafields
Metafields let you store custom data for products, orders, customers, and other resources in Shopify. They are useful for adding extra information like size guides, specifications, SEO data, or internal notes.

With DataEase, you can import, export, and update metafields easily using dynamic columns in your files.
📊 How Metafields Work in DataEase
When you export data from DataEase, metafields are shown as dynamic columns. This means each metafield gets its own column in the file, using a specific naming format:
metafield {namespace}.{name} [{type}]
Example:
metafield global.description_tag [single_line_text_field]
This structure tells DataEase (and Shopify) which metafield you’re referring to, and in what format.
🧠 Metafield Import Logic
- If a metafield is not in your import file, it will not be changed.
- If a metafield is in the file but empty, it will be deleted from Shopify.
- If a metafield has a value, it will be created or updated.
This makes it easy to manage metafields without overwriting data you don’t want to change.
🧩 Supported Metafield Types
Shopify supports a wide range of metafield types. You can see the full list here:
Use these types in your column headers when importing. For example:
metafield specs.material [multi_line_text_field] metafield shipping.weight [number_decimal]

- Enter your SEO titles in the column
- Import the updated file — your metafields are now live!
✅ Best Practices
- Use the correct format in square brackets for each metafield.
- Avoid overwriting important data — remove columns for fields you don’t want to change.
- Use export to back up your current metafields before making changes.
