NodeXL is a versatile social network analysis (SNA) and visualization tool which is designed as an Add-on to Microsoft Excel.
NodeXL is split in two versions – Pro and Basic. Both versions are used in many universities around the world for network research and education.
While NodeXL Basic is intended as a browser for files created in NodeXL Pro, it contains all the features needed to analyze and visualize a network data set. NodeXL Basic also allows for the manual authoring of networks by typing into the familiar Excel spreadsheet.
