First release:
Download the v1.zip file.
Drop your csv dataset in the folder.
Run the script.
Enter the name of the dataset file without inserting the .csv extension at the end. The script will automatically add the .csv extension.
Copy and Paste the name of the column that contains the GeoID/FIPS county codes. Do not change the format of the column name.
The script will then ask you to enter the name of the new .csv file. If you want to keep it the same with updated_ added at the beginning of the file, enter 12.
The script will then output the new .csv file with the updated GeoIDs/FIPS county codes.
