Latitude and Longitude to Spreadsheet

I have a list of 72 locations that I need to have the latitude and longitude coordinates for. The current state of the data is as follows:

- Coordinates: In Latitude and Longitude format

I would like the final deliverable to be in a spreadsheet, with each coordinate accurately listed under its corresponding location.

Please let me know if you have experience in accurately converting coordinates and can provide me with a spreadsheet as the deliverable.
