Thanks Jnix284 for your insight! For 1, routing via Excel gives no extra value (as I can just view the top 10 performing posts via HS analytics and create the “grid” on a slide manually).
For #2 (all-time top 20) I actually do exactly what you’re doing. I export to Excel and sort by raw views. I then copy-paste the rows onto a PowerPoint-embedded chart to get the column chart. Granted, for #2 it isn’t much extra work to go via export-sort-copy-paste… but if there’s a way to improve and cut out unnecessary extra seconds/minutes, I’m happy to try
