I have JSON coming from an external application, formatted like so:
{
"ticket_fields": [
{
"url": "https://example.com/1122334455.json",
"id": 1122334455,
"type": "tagger",
"custom_field_options": [
{
"id": 123456789,
"name": "I have a problem",
"raw_name": "I have a problem",
"value": "help_i_have_problem",
"default": false
},
{
"id": 456789123,
"name": "I have feedback",
"raw_name": "I have feedback",
"value": "help_i_have_feedback",
"default": false
},
]
}
{
"url": "https://example.com/6677889900.json",
"id": 6677889900,
"type": "tagger",
"custom_field_options": [
{
"id": 321654987,
"name": "United States,
"raw_name": "United States",
"value": "location_123_united_states",
"default": false
},
{
"id": 987456321,
"name": "Germany",
"raw_name": "Germany",
"value": "location_456_germany",
"default": false
}
]
}
]
}
The end goal is to be able to get the data into a TSV in the sense that each object in the custom_field_options array is grouped by the parent ID (ticket_fields.id), and then transposed such that each object would be represented on a single line, like so:
| Ticket Field ID | Name | Value |
|---|---|---|
| 1122334455 | I have a problem | help_i_have_problem |
| 1122334455 | I have feedback | help_i_have_feedback |
| 6677889900 | United States | location_123_united_states |
| 6677889900 | Germany | location_456_germany |
I have been able to export the data successfully to TSV already, but it reads per-line, and without preserving order, like so:
Using jq -r '.ticket_fields[] | select(.type=="tagger") | [.id, .custom_field_options[].name, .custom_field_options[].value] | @tsv'
| Ticket Field ID | Name | Name | Value | Value |
|---|---|---|---|---|
| 1122334455 | I have a problem | I have feedback | help_i_have_problem | help_i_have_feedback |
| 6677889900 | United States | Germany | location_123_united_states | location_456_germany |
Each of the custom_field_options arrays in production may consist of any number of objects (not limited to 2 each). But I seem to be stuck on how to appropriately group or map these objects to their parent ticket_fields.id and to transpose the data in a clean manner. The select(.type=="tagger") is mentioned in the query as there are multiple values for ticket_fields.type which need to be filtered out.
Based on another answer on here, I did try variants of jq -r '.ticket_fields[] | select(.type=="tagger") | map(.custom_field_options |= from_entries) | group_by(.custom_field_options.ticket_fields) | map(map( .custom_field_options |= to_entries))' without success. Any assistance would be greatly appreciated!
>Solution :
You need two nested iterations, one in each array. Save the value of .id in a variable to access it later.
jq -r '
.ticket_fields[] | select(.type=="tagger") | .id as $id
| .custom_field_options[] | [$id, .name, .value]
| @tsv
'
