About the CSV to JSON converter

Typical usage

It works well for temporary conversion of spreadsheet exports or business data before importing the result into another tool.

Header-first output

The beta version expects the first CSV row to define field names, which keeps the JSON structure easy to understand and avoids ambiguous output.
