Metafields Guru

Perfect for my use case and very easy to download/upload after my first mistake of forgetting to check the "download empty metafields" to get a template. I was uploading .csv files of JSON which I'm not familiar with and there was an error in the JSON code. I contacted them and they got back to me right away with Shopify's own help documents. I figured out my error and was able to complete my project. If you're doing a lot of uploading it's probably best to purchase the unlimited option. In my case I was able to do almost all my project with the test credits (although I did waste quite a few on my own trials and errors before reaching out) and I purchased additional credits at a very reasonable cost. I will absolutely use them for my next project coming up next month. If I were doing more I'd do the subscription for sure but I think topping up credits because I can't predict my workload is the best solution for me and I'm very grateful it's an option. Overall, great experience!

Very fast and competent help from the support team. Great app for effective editing and management of our metafields.

very helpful app! I like the support answers quickly and it's very helpful and ready to solve your problem!

Completely fantastic support. I have the most silly questions and Sasha always provides me with insanely good instructions with sceenshots. She even added some code that helped me with some padding where needed.
Always insanely was responsen aswell.

Extremely powerful app that really allows you to add as many custom fields of data as you need.

The fields are exposed in the Shopify API via connections such as Celigo, making it very easy to sync data between ERPs and Shopify.

Reaching out to support was easy, helpful, and a great experience.

I would highly suggest you looking at this program if you need more power with Metafieds and Shopify!
