Keep this thread alive. When I have time AND energy simultaneously, I'll figure out a way to automate the work. I should be able to make a CSV by saving the gaslog as html or text, cleaning it up a bit (vertical selection feature in Notepad++ FTW!), and so on.

Actually, come to think of it, if you're willing to use Internet Explorer and Microsoft Office for a moment, you may be able to just drag the page from IE into Excel. There's some really good integration there, and I recently made a CSV of a table on another website that way.

Ok, another thread just reminded me. I tried using Excel, works like a charm. Here's what I wrote in that thread:

5. Delete any extra stuff you didn't want, like the graph image that you couldn't help but select.
6. Crunch the numbers.

You know all that overcooked bullcrap Microsoft does? It occasionally pays off...

I just tried it with IE7 and Excel 2007, works great. Total miles: 12085.06. Total fuel used: 371.788. Average cost per gallon: 3.477051.

To make it a CSV:
- skip step 6 above
- delete any columns and rows you don't want (don't just delete the data, delete the actual column/row: use Edit->Delete in reasonable versions or Delete from the Home ribbon in 2007 (stupid ribbon crap))
- rearrange the columns if necessary
- File->Save As
- select CSV format
- enjoy

Edit: You can also do it with OpenOffice or online with Google Spreadsheets, and you don't need to use IE -- in fact, if you don't use IE and/or don't use Excel your results will be better.
