When to add CSV file to map viewer classic?

How are fields separated in a CSV file?
CSV and TXT files store information in plain text. The first row in the file defines the names for all subsequent fields. In CSV files, fields are always separated by commas. In TXT files, fields can be separated with a comma, semicolon, or tab.
Where can I find a CSV file on my computer?
If your CSV file is stored on a publicly accessible website, you can reference it from the map in Map Viewer or in Map Viewer Classic as a layer on the web. If the CSV file contains coordinate information, updates made to the CSV file on the web will appear in the map.
What happens when you update a CSV file on the web?
If the CSV file contains coordinate information, updates made to the CSV file on the web will appear in the map. If the CSV file contains address or place information, updates made to the CSV file on the web will not be reflected in the map. Add CSV files to your organization and share them so others can download the data.

Can a CSV file be treated as a text field?
