Export daily min/max temperatures?

Is there really no straightforward way, specifically from the web app, to export daily minimum and maximum temperature values over a selected date range (e.g. days, months, or years) for an outdoor station?

I understand that some users may prefer detailed readings (e.g. every 30 minutes or every 3 hours), but many of us are simply looking for basic daily min/max values, just like what’s commonly shown on weather apps, websites, or the evening news.

The current export options, such as "one per day/week/month," don't seem to provide this. The values generated are very confusing, as they don't match the daily minimum, maximum, or average, and they don’t match the 12:00:00 reading shown on the charts for the same day, even though the spreadsheet timestamps indicate that exact time (12:00:00). I've attached an example for reference.

Could you clarify:

1. How to export daily min/max temperature values in a simple format from the web app?

2. What exactly do the values labeled "per day", "per week", or "per month" represent?

I really hope there’s a way to get this fundamental data without having to manually process high frequency exports. It's the basic minimum that is expected for export options.
