How to create list data type value from search spl query ?

[vivekbs]

section for calculation_window_telemetry in /apps/SA-ITOA/default/savedsearches.conf:

"""

Current output:

{
	"data": {
		"calculationWindowUsage": {
			"customWindow": {
				"calculationWindowValueCount": {
					"calculation_window_1260_min": 1,
					"calculation_window_111_min": 1
				},
				"totalCount": 2
			},
			"predefinedWindow": {
				"calculationWindowValueCount": {
					"calculation_window_1440_min": 1,
					"calculation_window_15_min": 1,
					"calculation_window_1_min": 1,
					"calculation_window_5_min": 1
				},
				"totalCount": 4
			}
		}
	}
}

Expected output:

{
  "data": {
    "calculationWindowUsage": {
      "customWindow": {
        "calculationWindowValueCount": [{
          "calculation_window_value": 1260,
          "count": 1
        },
        {
          "calculation_window_value": 111,
          "count": 1
        }],
        "total_count": 2
    },
    "predefinedWindow": {
      "calculationWindowValueCount": [{
          "calculation_window_value": 1,
          "count": 1
        },
        {
          "calculation_window_value": 5,
          "count": 1
        },
        {
          "calculation_window_value": 15,
          "count": 1
        },
        {
          "calculation_window_value": 1440,
          "count": 1
        }],
        "total_count": 4,
      }
    }
  }
}

I required output in list of dictionary, can anyone help me on this.
Thank you.
