Do you need to run the input spreadsheet node in a workspace?

Unless the input spreadsheet is imported from a data import node, an Enterprise Data Configuration or connecting other external data sources, it won't need to be run in the workspace.

Any node that can be run will have a "Run to Node" icon (green arrow) on bottom left of the node. For instance, the Statistica spreadsheet "2(4-0).sta" is inserted into the workspace directly, it won't need be run again in the workspace and is ready to connect other downstream nodes.

This is also indicated by the white color of the node. Any node that is white is ready to be run by the subsequent node. Any node that is yellow, needs to be run before the subsequent node in the workspace can be run.
