Metafields Pro is a Shopify application that is based on popular application Metafields Editor which has 10,000+ Shopify users (https://apps.shopify.com/metafields-editor)
If you need to edit your metafields in bulk, the app allows to import and export metafields from/to comma separated values (csv) files. You can edit your data in a spreadsheet program and then import.
Please note that Metafields is a Shopify feature and it has nothing to do with SEO. Do not confuse it with meta tags for html. For more information about Metafields, please read this blog post from Shopify. https://www.shopify.ca/partners/blog/110057030-using-metafields-in-your-shopify-theme
Please make sure you have checked your import file format before starting an import. Read about the different file format we support here. http://support.webifytechnology.com/customer/en/portal/articles/1501770-import-and-export-metafields-from-to-csv
Depending on the size of your file, the import can take a long time. You will be notified by email when an import/export finishes so be sure to enter a valid email during import and whitelist emails from @webifytechnology.com to ensure emails get delivered.

There are some recent reviews by users regarding import/export stalling.
Please note that to do large amount of import/export, we are subject to something known as api limit by Shopify https://docs.shopify.com/api/introduction/api-call-limit . We have to basically pause the import if we are close to hitting the limit.
Depending on your store plan, your limit would be different. This pausing and restarting sometimes will cause our application to stall. We can also run into issue with Shopify’s API itself that it will time out. If you experience stalling, you can try again or contact us for support.
