Splitting out a master list into individual rows

I have a table that shows a list of countries as rows and tasks as columns. Inside each cell for a particular country and task will be one or more dates of when those tasks are due, separated with commas. I've done this to make the master table easy to read.

Master table

Is there an easy way to split those cells out on another sheet with a description column and a due date column?

etc...

I've simplified the example - in the real version there are over 100 countries so I needed a way to easily summarise and edit the task dates for future, but have it as individual rows in the new sheet so that I can upload that to sharepoint as a list.
