{
			"187597": "xxxx",
			"66023": "xxxx",
			"187597": "yyyy",
			"10068125": "xxxx",
			"677203": "xxxx",
			"677203": "yyyy",
			"10068125": "xxxx"
		}

after deserialization will look like this:

you will lose some values.

We can achieve it by grouping the values, but need the detail input string. Maybe you can share it as txt file with us? Thanks
