i tried to download the whole data-set from one channel as csv-file.
I used this URL:
but I get only the last 2666 Entries (i know 8000 entries are the maximum (2666*3 fields = 8000))
then i tried
but that does not work.
i also tried, to download the whole data-set in small pieces:
http://api.thingspeak.com/channels/(channel_id)/feed.csv&start=2011-11-20 00:00:00&end=2011-11-21 00:00:00
but that also does not work.
Can someone give me a hint how to use the "Retrieving Channel Feeds Method"

There is no "download" all option just yet. We are thinking of adding a button the web app that allows you to do that.
The best way to get the data is to use time slices on the API.
Time format is as follows: 2011-07-09 00:00:00 (%20 is an encoded space) – that's year, month, date, hours, minutes, seconds – all 2 digits long.

I'm struggling with this same problem...I can't figure out how to download data from my feed. I've tried several combinations, but here's the most recent, which looks ok?
It seems that no matter what I do, I get a -1 returned. This includes clicking on the feed links in the "Developer Info" tab in my channel's page...they all return -1. Thanks in advance for any advice...

As usual, the problem is with me. And as usual, within minutes of asking for help, I found my error. In my case, I needed to add a 'key' to the url to make it work (my feed is not public). Here's a url that works (for me, at least):

I build a web page tool that makes repeated api downloads, graphs them, and can export the whole data set as csv.
