Hi, I am importing a CSV into ArcMap. Everything has worked except for 3 columns I need to map. Some of the cells within these columns are blank and some are numeric. In Arcmap they show as <null> or their given numeric value. The column properties are string. I need to represent them under quantities. Is there a way of getting the CSV to recognize these columns as numeric and save as the same document and reopen the ArcMap with the updated table and not have to import two different excel documents?
