How do I save a set of values?

I am creating a matching card game in which you have the ability to make your own card sets (using text boxes to enter your own Words/Timetables).

How can i make it so these card sets, once created, can be saved to local storage and then used in later games?

All advice appreciated, Thanks in advance.

You could probably use dictionary or array, save it to json and import as json upon loading.
