A Bash command line tool for converting JSON to CSV



## Installation



Run the following command to install `jsonv`:



    $ curl -Ls https://raw.github.com/archan937/jsonv.sh/master/install.sh | bash



To uninstall, run this command:



    $ curl -Ls https://raw.github.com/archan937/jsonv.sh/master/uninstall.sh | bash



**Note: You also need to install `gawk`.**



## Usage



Call `jsonv` and pass the paths of the values used for the CSV columns (comma separated).

Optionally, you can pass a prefix for the paths as a second argument.



### Simple JSON



Parsing `examples/simple.json` (3 objects) without a path prefix:



    $ curl -Ls https://raw.github.com/archan937/jsonv.sh/master/examples/simple.json | jsonv id,name,age

    1,"Dagny Taggart",39

    8,"Francisco D'Anconia",40

    12,"Hank Rearden (a.k.a \"The Tank\")",46



### Complex JSON



Parsing `examples/complex-1.json` (1008 objects, file size 764KB) with a path prefix:



    $ curl -Ls https://raw.github.com/archan937/jsonv.sh/master/examples/complex-1.json | jsonv person.id,person.name,person.gender,person.balance,person.age,person.company response.data
