Add or update key value pair in JSON Object UiPath
A lot of times while doing API automation or dealing with JSON data as input or output for the business process.
Sometimes we need to add some new key-value pairs or update key-value pairs in the JSON object.
Let’s say we are getting JSON object as input and after processing the data you might need to add a new key-value pair stating the status of the transaction.
Where you need to add a new key-value pair to that JSON object.
In the same example mentioned above this time we already have a status key but this time we need to update the value which is in the JSON object.
In this article, we will see how we can achieve this using UiPath:
Let’s get into the practical implementation of this task:
Adding new key-value pair to JSON object:
Step1: The input JSON object that we are using for this example is shown below:
The input that we are using here is a JSON object and we will see how we can add a new key-value pair to this JSON object.
After processing the above JSON object we need to add a new key called Result.
Step2: Drag and Drop Invoke method activity from activities panel to designer panel as shown below:
- TargetObject – Provide your JSON object variable value.
- MethodName – As we are adding the new object to the existing object mention Add.
Let’s look at the parameters that are required for adding new object:
Here it requires two parameters and they are mentioned below:
- First Parameter – Provide the object key name here.
- Second Parameter – Provide the object value here.
In this example, we are adding a result key and value to the existing JSON object.
Step3 – After adding a new object to the existing JSON object that looks like below:
Updating the key value in JSON object:
In this example we will update the existing key value in the JSON object that is given above:
Step1; Drag and Drop assign activity from activities panel to designer panel as shown below:
- To – Provide the key-value where you want to update the key value. (eg: JsonOutput(“Status”))
- Value – Provide the value that needs to be updated.
Step2: The updated JSON object looks like below:
This is how we add or update the key-value pair of JSON object using UiPath.
