In a Shopify store, it is possible to use a CSV file to fill custom meta fields.
To update the meta fields for each product, one method is to use the Shopify API. The product handle and additional columns for each custom meta field you wish to add or modify can all be included in a CSV file. The CSV file can then be read using a computer language like Ruby or Python, and the meta fields can then be updated utilizing the Shopify API.
A Shopify app that allows importing custom metafields from a CSV file might be used as an alternative method to accomplish this. You may find a number of apps in the Shopify App Store that can assist you with this, including Metafields Manager, Advanced Custom Fields, and Metafields Editor. These programs often let you import custom meta fields from a CSV file manually or automatically without writing any code.
Thanks!
