Data from all experiments can be exported from Design Mode. This data export will join the data from all experiments into one data table. This data can be exported by clicking on the "data" drop down, and selecting "Export Data From All Experiments".
It may take some time for Riffyn to export the information as data is being exported from all experiments at once.
This type of data export is useful for exporting data from an entire process and having Riffyn automate the data consolidation.
