mentioning the csharp  code as well
using System;
using System.Collections.Generic;
using System.Globalization;
using System.Text;
using Newtonsoft.Json;
using Skyline.DataMiner.Scripting;

public static class Parameter
{
    public static class Instances
    {
        public const int tablePid = 300; // Replace with the correct table PID
    }
}

/// <summary>
/// DataMiner QAction Class: parse data.

public static class QAction

    /// <summary>
    /// The QAction entry point.
    /// </summary>

    public static void Run(SLProtocol protocol)
    {
        try
        {
            // Get Text based json data as a string.
            string source = Convert.ToString(protocol.GetParameter(200));

            // Deserialize Json contents
            Rootobject rootObjects = JsonConvert.DeserializeObject<Rootobject>(source);
            List<object[]> instances = new List<object[]>();

            // Convert Generated class into Connector Row data.
            foreach (Instance instance in rootObjects.Instances)
            {
                instances.Add(new InstancesQActionRow
                {
                    Instancesid_301 = instance.Id,
                    Instancesname_302 = instance.Name,
                    Instancesipaddress_303 = instance.IPAddress,
                    Instancescreatedfromtemplate_304 = instance.CreatedFromTemplate,
                    InstancesStatus_305 = instance.Status,
                }.ToObjectArray());
            }

            protocol.FillArray(Parameter.Instances.tablePid, instances, NotifyProtocol.SaveOption.Full);
        }
        catch (Exception ex)
        {
            protocol.Log("QA" + protocol.QActionID + "|" + protocol.GetTriggerParameter() + "|Run|Deserializing JSON text failed due to:" + Environment.NewLine + ex, LogType.Error, LogLevel.NoLogging);
        }
    }
}

public class Rootobject
{
    public Instance[] Instances { get; set; }
}

public class Instance
{
    public string Name { get; set; }

    public string IPAddress { get; set; }

    public long Id { get; set; }

    public bool CreatedFromTemplate { get; set; }

    public string Status { get; set; }
}

public class InstancesQActionRow
{
    public long Instancesid_301 { get; set; }

    public string Instancesname_302 { get; set; }

    public string Instancesipaddress_303 { get; set; }

    public bool Instancescreatedfromtemplate_304 { get; set; }

    public string InstancesStatus_305 { get; set; }

    // Convert the properties to an object array for table insertion
    public object[] ToObjectArray()
    {
        return new object[]         {
            Instancesid_301,
            Instancesname_302,
            Instancesipaddress_303,
            Instancescreatedfromtemplate_304,
            InstancesStatus_305,
        };
    }
}

so what mistakes i m doing and how to fix that and appreciable if get content for improvement this process.
