There are multiple ways of reading a .csv file. 1. Add the CSV Reader to the workspace and open the configuration dialog to choose the .csv file from the file system. 2. Drag and drop the .csv file from the file system explorer to the workspace. The CSV Reader node will be created on the workspace automatically and it will be configured to read the dropped file. To read the file properly, the appropriate column delimiter must be chosen in the configuration dialog.
