Why JSON? I don't see any benefits in storing `format.txt` as JSON (specially in a file with the txt extension). It just makes editing harder.

This would be better, IMHO:

    csvddfVersion: 1.2
    delimiter: ";"
    doubleQuote: true
    lineTerminator: "\r\n"
    quoteChar: "\""
    skipInitialSpace: true
    header: true
    commentChar: "#"
