# Output
There only output format currently supported in ecgen is JSON.
## JSON
Self-explanatory format. The curve dictionaries are enclosed in an array as you might generate more curves at once (`-c / --count`). The only interesting thing is that while generating invalid curves for a curve with the `-i / --invalid` option, the original curve is output first.
