CSV++

CSV++ takes a <DELIMITER> separated input file and a JSON format specification and turns it into Ruby Objects. See test/sample_inputs/simple.txt and test/sample_formats/simple.json for example.

Installation

Add this line to your application's Gemfile:

gem 'csvpp'

And then execute:

$ bundle

Or install it yourself as:

$ gem install csvpp

Usage

CSVPP.parse(
  input: 'test/sample_inputs/simple.txt',
  format: 'test/sample_formats/simple.json'
) # => [{"v1"=>34, "line_number"=>1, "v2"=>"foobar"}, {"v1"=>99, "line_number"=>2, "v2"=>"hi  there"}]

CLI

CSV++ comes with a CLI. To print a JSON representation of an input file, pass a file argument and provide a format specification file with -f, e.g.:

$ csvpp test/sample_inputs/simple.txt -f test/sample_formats/simple.json

{
    "vars": [
        {
            "line_number": 1,
            "v1": 34,
            "v2": "foobar",
            "v3": 1.1,
            "v4": false
        },
        {
            "line_number": 2,
            "v1": 99,
            "v2": "hi  there",
            "v3": 2.2,
            "v4": true
        },
        {
            "line_number": 3,
            "v1": null,
            "v2": "Missing",
            "v3": null,
            "v4": true
        }
    ]
}
