MapViewer creates thematic maps by linking worksheet data to areas or points on the map. If you need to display your own data on a map, MapViewer includes a full-featured worksheet that allows you to display, enter, edit, and save your data. You can read data files in many formats, including XLS, SLK, WKx, CSV, TXT, DAT, MDB, DBF, DB, BNA, and BLN. In the worksheet you can transform, sort, and calculate statistics on your data.
