I have recently upgraded to the latest version of NPM and NCM. Prior to the upgrade, I seem to remember being able to view and edit the node properties in a spreadsheet format, instead of going into each node individually. How can I do this now?
Perhaps you are thinking about custom properties? During the two years of work with npm did not find such an opportunity.
What you describe is very similar to the procedure for mass editing custom properties. Look at the picture below.
