You can have us export your Hunter-Tracker to a CSV file. To do this,
send an email to onbunkers@gmail.com with

The procedure to create a CSV file yourself is explained on the ONBOTA Hunter Database.

Then File Save as: CSV separated by ","

check the csv before uploading !

Perfect example of how every line in the csv should look like :
