What do you want to be added or improved?

As a user I want to have the expense tags to be exported together in the json / csv file.

Why do you need it?

• being able to get 100% details of my expenses exported.

How do you imagine it?

When exporting csv / json, it will include the tags information as well. For JSON it should be in array format (i.e. "tags": [ "tag1", "tag2", "tag3" ] While in CSV format it can be comma separated (i.e. "tag1,tag2,tag3")

Alternatively, there can be a tags dictionary with UUID as the identifier, which can be exported together
