jq: group objects by string - json

Question

I have some json from eurostat, which looks like this:

I would like to produce a csv file.
First, I need to concatenate .status with .value by string (sorry for my poor json knowledge) --> "status":{"57": "b"} with "value":{"57": 57.1}.
Second, I need to produce the same table as the original one (downloaded from eurostat).
I try many jq commands, like:
.status,.value | to_entries
I'm far from finding a solution.
Any help? I think map or map_values/group_by command are needed, but I don't really understand these functions.
EDIT :
I download data from eurostat.
I use their web service here, where I can download data in json format.
I would like to reproduce in shell same table as original, with jq. In my exemple, it should look like :
GEO/TIME,2010,2011,2012,2013,2014,2015,2016,2017
Belgique,"53,3","54,5","55,9","55,8","55,3","53,7","53,0","52,2"
Bulgarie,"36,2","33,8","34,5","37,7","43,1","40,5","35,1","35,1"
"Allemagne (jusqu'en 1990, ancien territoire de la RFA)","47,3","44,7","44,3","44,7","44,0","43,7","43,9","43,9"
Croatie,"48,0","48,5","47,8","47,6","48,1","48,3","46,9","45,0"
Chypre,"42,0","42,3","41,9","41,9","48,8","40,6","38,0","37,5"
Finlande,"54,8","54,4","56,2","57,5","58,1","57,1","55,9","54,0"
But json contain metadata, and Finlande must have 57,1b value.
I hope it's more clear with this edit.
And many thanks for your help.

Answer 1

Your question doesn't indicate very precisely what output you want, but hopefully you'll be able to adapt the following:
.value as $dict
| .status
| to_entries
| map( [.key, .value, $dict[.key]] )
| .[]
| #csv
With your input, and invoking jq with the -r option, this produces:
"57","b",57.1
