A Bash command line tool for converting JSON to CSV
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.
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.
