You could put summary entries in. Use your spreadsheet to add it up into groups of two or three months at a time. Then, later when you are not so busy, you could put in all your detailed data.
When you fill out a form in your web browser, the data is usually submitted as part of the URL that it retrieves. So, once you fill out the form and hit submit, instead of retrieving the page "http://www.gassavers.org/garage/addgaslog", it might try to retrieve something like "http://www.gassavers.org/garage/addgaslog?Date=20081030&Gallons=16&Miles=400&Notes =BlahBlahBlah". The server sees that and reads all the data that follows the '?' as your data.
It may be possible to generate the URLs from your spreadsheet. I think you could do something like:
http://www.gassavers.org/garage/addgaslog?Date=$B2&Gallons=$C2&Miles=$D2&Notes=$E2
where B2 is the cell with the date (properly formatted), C2 is the cell with the gallons, etc. I'm not a whiz with spreadsheets.
Ok, I just tried it. It's pretty messy.
Code:
http://www.gassavers.org/garage/addgaslog/garage.php?edit%5Bkey%5D=&edit%5Buid%5D=3351&edit%5Bgarage%5D=1399&edit%5Bmonth%5D=10&edit%5Bday%5D=30&edit%5Byear%5D=2008&edit%5Bdistance%5D=1111&edit%5Bfuel%5D=22&edit%5Bcost%5D=333&edit%5Bnotes%5D=My+Notes&op=Add+Gaslog+Entry
The "uid" and "garage" fields are individual to the person and vehicle. The "month" field is obvious:
&edit%5Bmonth%5D=10
The '10' there is the month. Day and year work the same, as do distance, fuel, cost, and notes, for which I entered 1111, 22, 333, and "My Notes" respectively. You'll notice that the spaces in "My Notes" were replaced with a '+', which is somehwat uncommon for these forms. Anyway, if you can make the spreadsheet make strings like that one, it could work, and you could then just save the list of URLs as a text file and use
wget for Windows as follows:
wget -l nameOfYourTextFile
See, piece of cake!
(It's either this, or do something more useful...and I'm one hell of a procrastinator.)
