I have put together a simple automated spreadsheet to help verify logbook entries and provide a running tally of time / cost etc.
Im sure it has been done already but please feel free to download and have a play. If you have any questions or feedback, please send them to the email address on the spreadsheet.
I am still working on improvements and if this is useful, I will continue to make the improvements available to all.
Please note that I haven't had a chance to fully test it so you might be able to find some 'features'

BTW - you need MS Excel installed.

(right click and 'Save as')
P.S - instructions can be found on the tab at the bottom of the spreadsheet.
Cheers
