World Map 30 X 32 Puzzle - 1 Million Cities by Latitude

It took some time but not that long actually! KoljiVriVoda told me how to use a single image file that can be divided, so I have an Excel file in which I combined citypopulation list with simplemaps.com coordinates (I had to fix some city name differences by hand). Then estimating latitude/longitude of the corners of the image file, Excel worked out in which 'piece' each city is in. With some other formulae type-ins get combined when more than one answer is possible, so now all I need to do is copy the quiz, change the 'formula' on Excel (eg I want the 'latitude' block of the city to be at most 1 away from the piece to be considered), import the answers and then 'map grid to answers'. But having just read PSTSCCH's I realized how silly I was in not thinking that I could have used a simpler approach for this one!

whoops that was silly of me, got too used to 'copy and paste and map grid to answers' that I didn't think of that... thanks for your suggestion, you're absolutely right!
