When you have a saved .json file you can import the options, data or alarm sounds here. The script should be able to import data files from any export file saved after July of 2016. I am hoping this will always work so you don't have to lose your data at all. Now some saved files will have alarm sounds and others will not. You can pick and choose which data you want to load in. So if you just want some old alarm sounds back make sure to leave the checkbox on for alarm sounds and turn off the import data checkbox.
