Took a little effort but I was able to import all my page views from #SimpleAnalytics into #Plausible. Found a JavaScript program that convert the Simple Analytics CSV into one suitable for Plausible, so I quickly rewrote it in Python and added support for importing location data which the original was missing. My Git server isn't open for registrations so you can send any patches to me via your text delivery medium of choice.
