This activity is used to convert a string to a JSON Object.

Properties

Input

  • Content: the name of the variable which stores the string content.

  • Output: the name of the variable used to store the result.

the output must be a JObject type.

Misc

  • Display Name: action display name in your implementation project

  • Wait Before: number milliseconds robot to wait before executing the action.

  • Wait After: number milliseconds robot to wait until moving to the next action.

  • Abort on Error: True/False

  • Retry Times: Specifies the number of times to retry an action if it doesn't end successfully. Default value 0 (no retry); Use -1 if you want to retry indefinitely.

Use Case

Potential Use Cases

  • Deserialize information captured via HTTP Rest Request, in order to use it in the workflow.

Examples of Using JSON Deserialization

Example 1

In this example, the robot will access the API of coindesk.com and retrieve the price of bitcoin in EUR.

Steps:

  • Create a new project

  • Create a new Sequence and rename it.

  • Create 2 variables: a string and a JSONobject

  • Add a new activity HTTP Rest Request in the newly created Sequence and edit the following parameters:

    • URL: "https://api.coindesk.com/v1/bpi/currentprice.json"

    • Method: GET

    • Output: a string variable (outputREST)

    • Response Code: an int32 variable (responseCode)

  • Add a new activity JSON Deserialization in the same Sequence and edit the following parameters:

    • Content: the same string variable (outputREST)

    • Output: a JObject variable (rate)

"Today, "+DateTime.Now + ", 1 bitcoin = " + rate["bpi"]["EUR"]["rate"] + " EUR"

where rate["bpi"]["EUR"]["rate"] is the JSON hierarchy (please see the screenshot below from JSON formater)

This is how your sequence should look like.

Watch the robot in action:

You can see how the JSON Deserialization activity is used in an example that incorporates multiple activities. You can check and download the example from here:
