Parse Request Response JSON

Hi, I have request json which contains multiple sensor details and parameter details. How can I parse the request json, update values on sensor and send the response back with success error status. I am doing it over TCP protocol using TCP request Node. Below is the sample request json. I have been trying to do it from couple of days but not able to do and blocked.
Request JSON
{
"sensorList": [{
"sensorId": "6131a8d409e2162ea1df532e",
"protocol": "tcp",
"paramList": [{
"paramName": "voltage",
"opValue": "220"
}]
},
{
"sensorId": "6131a8d409e2162ea1d423432e",
"protocol": "tcp",
"paramList": [{
"paramName": "temp",
"opValue": "220",
}]
}
]
}

Response JSON
{
"sensorList": [{
"sensorId": "6131a8d409e2162ea1df532e",
"protocol": "tcp",
"paramList": [{
"paramName": "voltage",
"opValue": "220",
"successCode":"",
"errorCode":""
}]
},
{
"sensorId": "6131a8d409e2162ea1d423432e",
"protocol": "tcp",
"paramList": [{
"paramName": "temp",
"opValue": "220",
"successCode":"",
"errorCode":""
}]
}
]
}

Thanks in advance.

Sorry - I can't import your NR flow.
Might be a good idea to read this and try again.

To export a Node-RED flow, you can use the built-in export feature, which allows you to save your flows as a JSON file. This JSON file can be imported into another Node-RED instance or shared with others. Here's how you can do it:

  1. Open Node-RED: Make sure you have Node-RED running and access it through your web browser.

  2. Access the Node-RED Editor: Open the Node-RED editor in your web browser by navigating to the appropriate URL (usually http://localhost:1880 or the URL of your Node-RED server).

  3. Select the Flow: In the Node-RED editor, select the flow or flows that you want to export. You can click and drag your mouse to select multiple nodes or click on a blank space in the workspace to deselect any selected nodes.

  4. Open the Export Dialog:

    • Right-click on one of the selected nodes or the blank workspace.
    • Click on the "Export" option in the context menu.
  5. Choose the Export Type:

    • You will see several export options. Choose the one that suits your needs:
      • Clipboard: This option copies the selected flow to your clipboard as JSON text.
      • File: This option allows you to save the selected flow as a JSON file to your local machine.
  6. Export to Clipboard:

    • If you chose "Clipboard," the JSON representation of your flow will be copied to your clipboard. You can then paste it into a text editor or share it with others.
  7. Export to File:

    • If you chose "File," a file dialog will open. Choose a location on your local machine to save the JSON file and provide a name for the file.
  8. Save the JSON File:

    • Click the "Save" or "Export" button to save the JSON file to your specified location.

Your Node-RED flow is now exported as a JSON file. You can share this file with others or import it into another Node-RED instance using the import feature. To import a flow, open the Node-RED editor, right-click on the workspace, and select "Import." Then, choose the JSON file you exported and follow the import instructions.
