On the issue of properties being object arrays

[mdxiaohu]

When the properties property of geojson is of type object array .

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "properties": [{
		name: "label",
		value: "country"
	  }, {
		name: "id",
		value: "123"
	  }],
      "geometry": {
        "coordinates": [
          100.82338732683246,
          27.39602756671043
        ],
        "type": "Point"
      }
    },
    {
      "type": "Feature",
      "properties": [{
		name: "label",
		value: "hospital"
	  }, {
		name: "id",
		value: "456"
	  }],
      "geometry": {
        "coordinates": [
          100.37069274307368,
          27.152961178937943
        ],
        "type": "Point"
      }
    },
    {
      "type": "Feature",
      "properties": [{
		name: "label",
		value: "car"
	  }, {
		name: "id",
		value: "789"
	  }],
      "geometry": {
        "coordinates": [
          101.27453687788176,
          27.128212817626633
        ],
        "type": "Point"
      }
    }
  ]
}

How should I assign an expression to the text field attribute of a symbol .
Make the text field of each point display text .
for example :

pointA: 'country',
pointB: 'hospital',
pointC: 'car'

Just like this example .

I need some help or reminder .

@HarelM Thank you .

That's not a valid geojson, properties should be an object not an array.
Try chatGPT, it can help a lot :-)

Thank you very much. I am currently using chatGPT .
However, due to limitations, it is a chatGPT of 3.5 .
The geojson format has been modified to be correct .
