Background Information

• Module Version: 5.5.5
  • Installed a global app via npm install -g @mrodrig/json-2-csv-cli
• Node: v22.5.1
• OS: macOS 13.6.9 Ventura
  • Terminal.app running zsh, nevertheless I used the $ symbol from bash, as it's more conventional.

The issue I'm reporting is with:

• [ ] json2csv
• [x] csv2json

I have...

• [x] searched to see if an issue has already been reported.
• [x] tried upgrading to the latest version of json-2-csv (since the issue may already be fixed).
• verified that my JSON/CSV data is valid (using something like http://jsonlint.com or https://csvlint.io/).
  • does not apply as my bug occurs with csv2json -h which uses no input/output at all.

@mrodrig it's a minor bug but still I'd appreciate a reaction. Thanks!
