How can I combine this with jq? Both work independently but I can't make them work together:
jq '.objects[].addresses[] | .id, .ipValue.ipStr, .hostName'
jq '.objects[] | .id, .name'
This does not work:
jq '.objects[] | .id, .name, .addresses[] | .id, .ipValue.ipStr, .hostName'
In other words, print the .id., .name, and iterate over addresses array and print .id, .ipValue.ipStr and .hostName??
You were close, pipe operator has a higher precedence than comma operator.
.objects[] | .id, .name, (.adresses[] | .id, .ipValue.ipStr, .hostName)
It looks like you're looking for something along the lines of:
jq -r '.objects[]
| [.id, .name] + (.addresses[] | [.id, .ipValue.ipStr, .hostName])
| #csv'

Not quite getting it. I can produce multiple lines but cannot get multiple entries to combine. Looking to take Source JSON and output to CSV as shown:
Source JSON:
[{"State": "NewYork","Drivers": [
{"Car": "Jetta","Users": [{"Name": "Steve","Details": {"Location": "Home","Time": "9a-7p"}}]},
{"Car": "Jetta","Users": [{"Name": "Roger","Details": {"Location": "Office","Time": "3p-6p"}}]},
{"Car": "Ford","Users": [{"Name": "John","Details": {"Location": "Home","Time": "12p-5p"}}]}
]}]
Desired CSV:
"NewYork","Jetta","Steve;Roger","Home;Office","9a-7p;3p-6p"
"NewYork","Ford","John","Home","12p-5p"
JQ code that does not work:
.\[\] | .Drivers\[\] | .Car as $car |
.Users\[\] |
\[$car, .Name\] | #csv
You're looking for something like this:
.[] | [.State] + (
.Drivers | group_by(.Car)[] | [.[0].Car] + (
map(.Users) | add | [
map(.Name),
map(.Details.Location),
map(.Details.Time)
] | map(join(";"))
)
) | #csv
$ jq -r -f tst.jq file
"NewYork","Ford","John","Home","12p-5p"
"NewYork","Jetta","Steve;Roger","Home;Office","9a-7p;3p-6p"
$
Not quite optimised, but I though't I'd share the general idea:
jq -r 'map(.State as $s |
(.Drivers | group_by(.Car))[]
| [
$s,
(map(.Users[].Name) | join(";")),
(map(.Users[].Details.Location) | join(";")),
(map(.Users[].Details.Time) | join(";"))
])
[] | #csv' b
map() over each state, remember the name (map(.State as $s | )
group_by(.Car)
Create an array containing all your fields that is passed to #csv
Use map() and join() to create the fields for Name, Location and Time
This part could be improved so you don't need that duplicated part
Output (with --raw-output:
"NewYork","John","Home","12p-5p"
"NewYork","Steve;Roger","Home;Office","9a-7p;3p-6p"
JqPlay seems down, so I'm still searching for an other way of sharing a public demo
Far from perfect, but it builds the result incrementally so it should be easily debuggable and extensible:
map({State} + (.Drivers[] | {Car} + (.Users[] | {Name} + (.Details | {Location, Time}))))
| group_by(.Car)
| map(reduce .[] as $item (
{State:null,Car:null,Name:[],Location:[],Time:[]};
. + ($item | {State,Car}) | .Name += [$item.Name] | .Location += [$item.Location] | .Time += [$item.Time]))
| .[]
| [.State, .Car, (.Name,.Location,.Time|join(","))]
| #csv
I have an aws query that I want to filter in jq.
I want to filter all the imageTags that don't end with "latest"
So far I did this but it filters things containing "latest" while I want to filter things not containing "latest" (or not ending with "latest")
aws ecr describe-images --repository-name <repo> --output json | jq '.[]' | jq '.[]' | jq "select ((.imagePushedAt < 14893094695) and (.imageTags[] | contains(\"latest\")))"
Thanks
You can use not to reverse the logic
(.imageTags[] | contains(\"latest\") | not)
Also, I'd imagine you can simplify your pipeline into a single jq call.
All you have to do is | not within your jq
A useful example, in particular for mac brew users:
List all bottled formulae
by querying the JSON and parsing the output
brew info --json=v1 --installed | jq -r 'map(
select(.installed[].poured_from_bottle)|.name) | unique | .[]' | tr '\n' ' '
List all non-bottled formulae
by querying the JSON and parsing the output and using | not
brew info --json=v1 --installed | jq -r 'map(
select(.installed[].poured_from_bottle | not) | .name) | unique | .[]'
In this case contains() doesn't work properly, is better use the not of index() function
select(.imageTags | index("latest") | not)
This .[] | .[] can be shorten to .[][] e.g.,
$ jq --null-input '[[1,2],[3,4]] | .[] | .[]'
1
2
3
4
$ jq --null-input '[[1,2],[3,4]] | .[][]'
1
2
3
4
To check whether a string does not contain another string, you can combine contains and not e.g.,
$ jq --null-input '"foobar" | contains("foo") | not'
false
$ jq --null-input '"barbaz" | contains("foo") | not'
true
You can do something similar with an array of strings with either any or all e.g.,
$ jq --null-input '["foobar","barbaz"] | any(.[]; contains("foo"))'
true
$ jq --null-input '["foobar","barbaz"] | any(.[]; contains("qux"))'
false
$ jq --null-input '["foobar","barbaz"] | all(.[]; contains("ba"))'
true
$ jq --null-input '["foobar","barbaz"] | all(.[]; contains("qux"))'
false
Say you had file.json:
[ [["foo", "foo"],["foo", "bat"]]
, [["foo", "bar"],["foo", "bat"]]
, [["foo", "baz"],["foo", "bat"]]
]
And you only want to keep the nested arrays that don't have any strings with "ba":
$ jq --compact-output '.[][] | select(all(.[]; contains("bat") | not))' file.json
["foo","foo"]
["foo","bar"]
["foo","baz"]
I need to get some values from a json file with JQ. I need to get a csv (Time, Data.key, Lat, Lng, Qline)
Input:
{
"Time":"14:16:23",
"Data":{
"101043":{
"Lat":49,
"Lng":15,
"Qline":420
},
"101044":{
"Lat":48,
"Lng":15,
"Qline":421
}
}
}
Example output of csv:
"14:16:23", 101043, 49, 15, 420
"14:16:23", 101044, 48, 15, 421
Thanks a lot.
I tried only to:
cat test.json | jq '.Data[] |[ .Lat, .Lng, .Qline ] | #csv'
Try this:
{ Time } + (.Data | to_entries[] | { key: .key | tonumber } + .value)
| [ .Time, .key, .Lat, .Lng, .Qline ]
| #csv
Make sure you get the raw output by using the -r switch.
Here's another solution that doesn't involve the +'s.
{Time, Data: (.Data | to_entries)[]}
| [.Time, (.Data.key | tonumber), .Data.value.Lat, .Data.value.Lng, .Data.value.Qline]
| #csv
Here is another solution. If data.json contains the sample data then
jq -M -r '(.Data|keys[]) as $k | {Time,k:$k}+.Data[$k] | [.[]] | #csv' data.json
will produce
"14:16:23","101043",49,15,420
"14:16:23","101044",48,15,421
I have this command that is working..
cat ~/Desktop/results.json | jq '.[] | .environmentStatuses[].deploymentResult | select(.key.entityKey.key=="39583746-39747586") | .lifeCycleState '
I want to pass the entity key as variable , tried the below ones ,but none seems to work-
enkey="39583746-39747586"
cat ~/Desktop/results.json | jq '.[] | .environmentStatuses[].deploymentResult | select(.key.entityKey.key=="""${enkey}""") | .lifeCycleState '
cat ~/Desktop/results.json | jq '.[] | .environmentStatuses[].deploymentResult | select(.key.entityKey.key=="${enkey}") | .lifeCycleState '
When trying to use extra parameters in your filters, use the --arg option to pass them in. Don't rely on the shell to insert it into your filter string, keep that separate.
jq --arg key "$enkey" '.[] |
.environmentStatuses[].deploymentResult |
select(.key.entityKey.key == $key) |
.lifeCycleState' ~/Desktop/results.json
This worked for me :
jq '.[] | .environmentStatuses[].deploymentResult |
select(.key.entityKey.key == "'$key'") |
.lifeCycleState' ~/Desktop/results.json
--arg does not works as expected ...
Trying to flatten a JSON file to CSV in UNIX but getting an error message. Any help here to get the contents copied to CSV will be appreciated:
Command:
cat Filename.json | jq --raw-output '._data.data[] | [.Date, .Object, .ID, .Name ] | #csv' > /home/Filename.csv
Error:
jq: error: Cannot iterate over null
cat Filename.json | sed 1d | sed 's/},/}/' | jq --raw-output '. | [.Date, .Object, .ID, .Name ] | #csv'
