Foreword
- Thanks for providing the app! I use your app via CLI.
- I looked into the manpage but found no options to achieve my goal.
- So I think this is de facto a feature request
User Story
From a large JSON file containing a lot of stuff I want the option to select only a particular object for export to CSV.
With a syntax like --select "path.to.object"
Or another argument name you deem appropriate as the mnemonics -s and -S are both already taken.
Given example.json
{
"version": "1.5",
"global_option_a": "something",
"global_option_b": "else",
"global_option_c": 123,
"people": [
{
"firstname": "Jon",
"lastname": "Doe",
"birthday": "1978-02-19",
"gender": "m"
},
{
"firstname": "Jane",
"lastname": "Doe",
"birthday": "1982-04-21",
"gender": "f"
},
{
"firstname": "Dave",
"lastname": "Meyer",
"birthday": "1964-12-03",
"gender": "m"
}
],
"locations": {
"Europe": [
{
"ID": "1",
"Name": "London"
},
{
"ID": "2",
"Name": "Paris"
},
{
"ID": "3",
"Name": "Madrid"
}
],
"Asia": [
{
"ID": "4",
"Name": "Tokio"
},
{
"ID": "5",
"Name": "Seoul"
}
]
}
}
To get people.csv I'd run…
$ json2csv example.json --select "people" > people.csv
which results in:
firstname,lastname,birthday,gender
Jon,Doe,1978-02-19,m
Jane,Doe,1982-04-21,f
Dave,Mayer,1964-12-03,m
To get locations-asia.csv I'd run
$ json2csv example.json --select "locations.Asia" > locations-asia.csv
which results in:
ID,Name
4,Tokio
5,Seoul
