I have a simple JSON object that may have the following structure:

{
  "data":{
     "k1":"v1",
     "k2":"v2"
  }
}

The object can contain any number of key-value pairs, but it will always be flat, meaning there are no nested objects. I'm looking to construct a string in the format of "k1:v1:k2:v2" using JMESPath. Is it possible to achieve this using JMESPath?

I was trying to use [data.keys(@),data.values(@)].join(':',[]) But this results in: "k1:k2:v1:v2"

You'd need to be able to zip the two arrays (of keys and values) together in order to do this, which is not an existing functionality, unfortunately. – β.εηοιτ.βε Aug 11 '23 at 18:56
So it is impossible to do with just jmespath? – SimonE Aug 11 '23 at 19:40
