How can I convert Shopify product metafields into HTML format?

edit

There are a few steps to convert Shopify product metafields into HTML format:

1. Retrieve the product metafield value using the Shopify API or in the Shopify admin panel.

2. Identify the data type of the metafield value. The data type can be a string, integer, float, or JSON.

3. If the metafield value is a string, you can simply output it as HTML text. Ensure that any special characters are properly escaped to prevent HTML injection attacks.

4. If the metafield value is an integer or float, you may want to format it using a number formatter before outputting it as an HTML text.

5. If the metafield value is in JSON format, you can parse the JSON string into an object or array and use it to generate HTML dynamically using JavaScript.

6. Once you have generated the HTML text, you can insert it into your Shopify theme using Liquid code. Use the {{ product.metafields }} object to access the product's metafields and their values.

Here is an example Liquid code snippet to display a product's metafield value in HTML format:

{% if product.metafields.my_metafield %}
  <div class="metafield">
    <h4>{{ product.metafields.my_metafield.title }}</h4>
    <p>{{ product.metafields.my_metafield.value }}</p>
  </div>
{% endif %}

Replace my_metafield with your actual metafield key and customize the HTML markup to fit your design.
