I am adding a very simple .csv file to a new map. The file has two columns, which are private data so I can't add the file here. The first column is a list of census tract ID numbers, the second is a value associated with that census tract. When I try to add the file it gets corrupted in some way. If I bring the file in directly it changes everything (ID numbers and values) to zeroes. If I try to add a column of row numbers (thought that might help), it imports the row numbers, eliminates the ID numbers and shows the values column twice. This is such a simple task, I can't figure out what I could possibly be doing wrong. There are no spaces or special characters in the column names. It isn't using the correct column names, however. It just uses the name of the file as the column name. I'm new to Pro, but am a longtime user of ArcMap. What am I missing?
