Is it possible to use jq to turn the following JSON data
[
"a": null,
"b": [
"c": "cc",
"d": "dd1"
,
"c": "cc",
"d": "dd1",
"e": "ee",
"f": "ff"
]
,
"b": [
"c": "cc",
"d": "dd2",
"e": "ee",
"f": "ff"
]
]
into
[
"a": null,
"b": [
[
"cc", "d1"
],
[
"cc", "d1", "ff"
]
]
,
"b": [
[
"cc", "d2", "ff"
]
]
]
?
Note that the purpose is to reduce the b list with certain elements of its items based on a condition. The condition assigns the string d1 if the value of d is dd1, otherwise d2 is assigned if dd2 is present.
The following unsuccessful attempt demonstrates the idea:
$ jq -r '..b = [..b.c, ?, ..b.f?]'

@oguzismail See the updated question. I am unaware how to address the conditional part and how to update each element individually.

This is probably not the best way to do what you want, but it does get the desired output and it has the conditional you asked about.
jq '..b |= map(
[ .c,
(if .d == "dd1" then "d1" elif .d == "dd2" then "d2" else . end),
.f // empty
] )'

Without changing the value of the d key, you would use this jq filter:
jq '..b|=(to_entries|map(.value))' file
That updates the b array into all values of the inner objects.
If you want to update the d, you could use this filter:
jq '..b |= (to_entries|
map(
if(.key=="d") then
.value|=sub("d+";"d")
else .
end
|.value)
)' file
that adds a check if the key is d the associated value is updated to remove the duplicated d character from the string. This requires jq to support for regex (to be able to use the sub function).
