I am trying to use a joined CSV file that contains more than 1400 records to a table. when I tried to use the field calculator to replace the old data with the new data it crashes and closes the ArcGIS 10.5.1. Is there any way to fix this? or there is another way to do it besides copying and pasting one out time? I was trying to use ArcGIS pro but the data is on a Geometric network that I cannot edit.
If your working with a dataset that you cannot edit that could be your issue.
Perhaps try this. Bring in your .csv into a database and make it an actual GIS table.
There could be an issue with your .csv file.
