Sorting what needs a category

Step by step

1. 1 Some rows land without a category The count is the way in
2. 2 Each row is one merchant Six purchases became three questions
3. 3 Open one to see what is in it Three dates, three amounts, one question
4. 4 Pick the category once The app's own list, not a guess
5. 5 One answer settled the whole group The merchant is gone from the list
6. 6 Sort these out walks the rest One merchant at a time, in order
7. 7 Done for now leaves it as it is Stopping halfway loses nothing
