Delete duplications in JSON file - json

Question

I am trying to reedit json file to print only subgroups that has any attributes marked as "change": false.
Json below:
{"group":{
"subgroup1":{
"attributes":[
{
"change":false,
"name":"Name"},
{
"change":false,
"name":"SecondName"},
],
"id":1,
"name":"MasterTest"},
"subgroup2":{
"attributes":[
{
"change":true,
"name":"Name"
},
{
"change":false,
"name":"Newname"
}
],
"id":2,
"name":"MasterSet"},
}}
I was trying to use command:
cat test.json | jq '.group[] | select (.attributes[].change==false)
which produce needed output but with duplicates. Can anyone help here? Or shall I use different command to achieve that result?

Answer 1

.attributes[] iterates over the attributes, and each iteration step produces its own result. Use the any filter which aggregates multiple values into one, in this case a boolean with the meaning of "at least one":
.group[] | select(any(.attributes[]; .change==false))
{
"attributes": [
{
"change": false,
"name": "Name"
},
{
"change": false,
"name": "SecondName"
}
],
"id": 1,
"name": "MasterTest"
}
{
"attributes": [
{
"change": true,
"name": "Name"
},
{
"change": false,
"name": "Newname"
}
],
"id": 2,
"name": "MasterSet"
}

Looks to me like the duplicate is NOT a duplicate, but a condition arising from a nested sub-grouping, which gives the appearance of a duplicate. You should look to see if there is a switch to skip processing sub-groups when the upper-level meets the condition, thereby avoiding the perceived duplication.
