How do I erase unused metafields?

[Platypyrus]

Recently I did an export with Matrixify and saw a bunch of metafields full of weird data cluttering up my spreadsheet.

I saw the name "Product Wiz" mentioned and so I think it's undeleted data from that app. I did a trial of it recently and it was very difficult to remove. 

I can't seem to find the metafield in Shopify to delete it. Can anyone help?

Hi @Platypyrus 

These would be Metafields without definition, thus they only exist as values for individual products/variants.

There are two best ways to delete them:

1 - As you already are using Matrixify app - you can also use our app to bulk remove those values from your store.

Make sure to export all Products without any filters selected and for the Metafields that you wish to remove, set clear values in that Metafield column in all rows. So that you only have the column header in that column.

Save the file and import back. Thus such an import would set it empty for all Products and it would no longer exist in the store.

2 - Another option is to go into your stores Admin -> Settings -> Custom data -> Products (or Variants if those are variant metafields) -> View unstructured metafields section. Then find the metafield you wish to delete and press "Add definition" for it. Select any type and name that Shopify allows and create the definition.

Once created locate that Metafield definition in Assigned to all Products section for definitions, open it and press Delete for it.

This will open a pop-up message where you can select "Delete field and its saved values" and delete.

Thus you would achieve the same that the metafield would be deleted as this would also remove that metafields values from all products where it is set.

I hope this helps, if you need further details feel free to reach out to our support directly!
