How to collect global data for 250+ countries?


Attempting to collect data, from multiple offices across the globe, to show how many locations a company has in various countries. Currently, there are 256 countries and roughly 5 "details" fields. We were hoping to be able to collect via a form; however, we have not had any luck. Any suggestions on best way to collect? I have attached an example of the type of file currently being distributed via Excel. Thank you!
