You can copy process data to the clipboard or save it as a CSV file.

The Copy submenu of the Process context menu has three commands:
Hidden columns are not included. If a filter is active, only the rows that pass the filter are copied.
Choose Processes > Export processes to CSV from the main menu. A save-file dialog opens with a default name of the form processes-YYYY-MM-DD-HH-MM-SS.csv.
CSV is the only export format. The file opens directly in Excel and any text editor.
The export is a snapshot: the visible columns in the current order, sorted as the screen is sorted, only the rows that pass any active filter.
