🛠️ How to Use

ruby converter.rb --from FORMAT --to FORMAT input_file output_file

FORMAT: json | yaml | csv | xml

input_file: your source file path

output_file: destination file path

Examples

ruby converter.rb --from json --to csv data.json data.csv
ruby converter.rb --from csv --to yaml data.csv data.yml
ruby converter.rb --from xml --to json data.xml data.json

Tips & Notes

XML expects a root with multiple <item> children containing data fields

CSV with headers → array of hashes; without headers → array of arrays supported

If you see errors about .keys on Array, check your input file format — might be nested arrays instead of hashes

Script aims to handle common cases, but weird formats might cause trouble
