JSON to CSV file converter in Ruby

Git clone or download this repository.

Update json_file_path with your json file path and name, and csv_result_path with the desired CSV output file name (make sure to use an existing directory for the output).

# --- Select desired path ---
json_file_path = "foo/bar/my_json_file.json"
csv_result_path = "my_result.csv"
# ---------------------------

Run the json_to_csv.rb file

$ ruby json_to_csv.rb

A new .csv file will be created.

Don't forget to change your CSV output file name when you convert a new file, as every new execution will overwrite the content of the existing file.

Note that only JSON format is valid.

Nested hashes are supported. e.g.

[
  {
    "id": 0,
    "email": "[email protected]",
    "tags": [
      "consectetur",
      "quis"
    ],
    "profiles": {
      "facebook": {
        "id": 0,
        "picture": "//fbcdn.com/a2244bc1-b10c-4d91-9ce8-184337c6b898.jpg"
      },
      "twitter": {
        "id": 0,
        "picture": "//twcdn.com/ad9e8cd3-3133-423e-8bbf-0602e4048c22.jpg"
      }
    }
  }
