Regex to pick values from specific json key - json

My json string:

],

}
I want to extract the values for these particular keys (each of which has 3 instances in the above json string):
count
step_conv_ratio
What is the correct regex so that I will get 1853, 741, 174 for count; and 1, 0.39989206691851054, 0.23481781376518218 for step_conv_ratio?
Unmarshalling this to a Go struct is not ideal, since it has dynamic json field name, so I cannot use a static struct with static json tag to unmarshal. Hence I'm thinking of using regex.

Answer 1

Consider the comments about unmarshalling. Else the regex you are looking for is:
`"count": ([0-9]+)|"step_conv_ratio": ([0-9.]+)`
then the number will be in the second or the third element of the slice that contains the matches (e.g. after FindAllStringSubmatch()) depending on it's a count or a step_conv_ratio.
