Rasa Testing: get csv/json output rather than plots

Is there a way to get the data shown as plots (confidence distribution histograms and confusion matrices) as csv or json instead?

The plots are great but having access to that data will allow me to make my own manipulations and comparisons. I can write scripts to manipulate the *_errors.json files but then I’m missing out on the correctly classified data.

I went through the docs but didn’t find anything regarding this.
Thanks in advance!
