• start:
    set:
      data:
        name: Joe Customer
        order_id@int: 54321
        status:
          text: shipped
          tracking_id: Z1F238
    return:
      encoded: {{data|json_encode}}
      pretty: {{data|json_encode|json_pretty}}

• __return:
    encoded: '{"name":"Joe Customer","order_id":54321,"status":{"text":"shipped","tracking_id":"Z1F238"}}'
    pretty: |-
      {
          "name": "Joe Customer",
          "order_id": 54321,
          "status": {
              "text": "shipped",
              "tracking_id": "Z1F238"
          }
      }

Converting from JSON using @json

The @json annotation converts a JSON string back into native types.

• start:
    set:
      json_string@text: {"name":"Joe Customer","order_id":12345}
      decoded_data@json: {{json_string}}
    
    return:
      customer: {{decoded_data.name}}
      order_num@int: {{decoded_data.order_id}}

• __return:
    customer: Joe Customer
    order_num: 12345

Converting from JSON using json_decode

Here is an example of using the json_decode() function to convert JSON strings back into native data types.

• automation
• output

• start:
    set:
      json_string@text: "{\"name\":\"Joe Customer\",\"order_id\":12345}"
      decoded_data@json: {{json_decode(json_string)}}
    
    return:
      customer: {{decoded_data.name}}
      order_num@int: {{decoded_data.order_id}}

• __return:
    customer: Joe Customer
    order_num: 12345
