I love the new Garmin devices! However, I cannot buy one until there is a viable export of daily stats to CSV.
My current understanding is from the "reports" section of Connect, if you are looking at 7 days, you can export 7 days, if you are looking at "weekly" you can export weekly totals for what is on the screen. What you get in the 7 day file is a single variable (steps OR sleep, not all variables at once) into a spreadsheet that is labelled simply with the day of week, and the file is named generically. So I can't even viably just hack away 7 days at a time exporting separate files for a couple of months or a year, and then manually combine them, because of the likelihood of getting them out of order is too high.
Please look at what Jawbone (excellent) and Fitbit (acceptable) have for exporting data. Until there is a viable way to get my data out of the Garmin system (so I can combine with other data of interest) I have to use some other company's product - but I really like the Garmin devices!
I'd love to be told I've missed something and there is a great export, or else that there is a third party app solution available.
I posted about this back when the first vivoactive came out, and it hasn't been solved in the last two years.
