j2tn

Prototype for a semi-normalized way to convert a nested JSON document to CSV

Requirements

You will need to install the following Perl modules

• YAML
• JSON
• Text::CSV_XS

For most operating systems this can be achieved by install the following a packages

• perl-json
• perl-yaml
• perl-text-csv-xs or perl-text-csv

Examples for Linux

help

command

./j2tn.pl help

output

./j2tn.pl command [options,...] [arguments,...]

commands:
  to-csv in-file-name out-file-name
     use - for the out-file-name to go to std-out
  debug [debug-bit-flag] command
     1 => function calls
     2 => current location
     4 => parsed json
     8 => unparsed json
    16 => internal processed data just before output
  speak command
    echo the command

to-csv

command

./j2tn.pl to-csv <(echo '[{"column1":"data1","column2":[1,2],"column3":3}]') -

output

_normlized_,column3,column1,column2
"{""column2"":[1,2]}",3,data1,"1; 2"

Note

To manipulate the csv file I suggest xsv

• xsv Source
• xsv Binary Release
