If you have python, you can write a small script that uses pymavlink to extract it into any format you like. See mavlogdump for an example.
Otherwise you can use the "Convert to Text" button in Mission Planner. That will produce a txt file in the same directory as the tlog. Then you'd need to import that using whatever tools you like.
It would be nice to have a "convert to CSV" button in the planner that converted one packet type to CSV. Maybe ask Michael Oborne to add it?
the planner has a tlog to text conversion, if you use excel to import that data with a space and "=" delimiter you can get this data.
This is what I have been look for and is a life saver. By chance is there a column header somewhere? I know some of the columns, but others I can't quite figure out. For instance column D
After you Convert to Text, each number has the header attached to it.

I got that but what about the 55, 11, F4, 1, 1, 23 in the example you posted?
I have no idea. I just extract the info that I'm interested in. :D
It was worth asking. I guess I will do the same.
