Help Needed: Looping and Displaying Parsed JSON Metafields in Shopify Liquid.

Hi everyone,

I’m working on a Shopify store and trying to loop through a metafield that contains JSON data for “data sheets.”
Here’s an example of the JSON stored inside the metafield:

{% if product.metafields.data_url != blank %}
  {% assign urldata = product.metafields.data | parse_json %}
  
  
    {% for url in urldata %}
      - {{ url.name }}
      
    {% endfor %}
  

{% endif %}

But I’m not sure if this is the best practice, and sometimes sheet.name or sheet.url is missing or doesn’t render correctly.
Is there a better or safer way to handle parsed JSON in Shopify Liquid?
How can I make sure it won’t break if the metafield is empty or has missing keys?

Any help or tips would be really appreciated!
Thanks in advance

@ErSanjay You ommited any example of actual JSON code only an attempted usage.

To access one json type metafield use the full qualified namespace and key product.metafields.namspace.key

For some metafields type also use the .value value to access the value; yes that’s how shopify makes things.

Going over an entire namespace for multiple separate metafields with different keys to expose properties as liquid object & properties is not a straigthfoward thing that will vary widly based on setup, the data and way it needs to be used.

See the https://community.shopify.dev/ for advanced api questions that include more detail.
