(Note this is in Beta testing, so please be patient as I get all the bugs sorted out)
Data that you have from another program can be imported into Car Logbook. First you will need to open the data in Excel or similar spreadsheet application.
The data can be copied from Excel directly or saved as a CSV.
Then open http://binaryarm.com/carlogbook/import.html on your computer, and follow the instructions.
If you have any problems, send an email to: Car Logbook support
