How to convert complex JSON to CSV using JQ 1.4 - json

Question

I am using JQ 1.4 on Windows 64 bit machine.
Below are the contents of input file IP.txt
{
"results": [
{
"name": "Google",
"employees": [
{
"name": "Michael",
"division": "Engineering"
},
{
"name": "Laura",
"division": "HR"
},
{
"name": "Elise",
"division": "Marketing"
}
]
},
{
"name": "Microsoft",
"employees": [
{
"name": "Brett",
"division": "Engineering"
},
{
"name": "David",
"division": "HR"
}
]
}
]
}
{
"results": [
{
"name": "Amazon",
"employees": [
{
"name": "Watson",
"division": "Marketing"
}
]
}
]
}
File contains two "results". 1st result containts information for 2 companies: Google and Microsoft. 2nd result contains information for Amazon.
I want to convert this JSON into csv file with company name and employee name.
"Google","Michael"
"Google","Laura"
"Google","Elise"
"Microsoft","Brett"
"Microsoft","David"
"Amazon","Watson"
I am able to write below script:
jq -r "[.results[0].name,.results[0].employees[0].name]|#csv" IP.txt
"Google","Michael"
"Amazon","Watson"
Can someone guide me to write the script without hardcoding the index values?
Script should be able generate output for any number results and each cotaining information of any number of companies.
I tried using below script which didn't generate expected output:
jq -r "[.results[].name,.results[].employees[].name]|#csv" IP.txt
"Google","Microsoft","Michael","Laura","Elise","Brett","David"
"Amazon","Watson"

Answer 1

You need to flatten down the results first to rows of company and employee names. Then with that, you can convert to csv rows.
map(.results | map({ cn: .name, en: .employees[].name } | [ .cn, .en ])) | add[] | #csv
Since you have a stream of inputs, you'll have to slurp (-s) it in. Since you want to output csv, you'll want to use raw output (-r).
