I have been banging my head on this for a few weeks now and thought I would start asking around. I have an unidentified database structure that I would like to be able to convert back and forth between a csv or excel file.
In excel the format would look like this:

0 1 4
433 31 40
434 51 46

433:0=433,1=31,4=40
434:0=434,1=51,4=46

Any help in identifying or pointing me in the right direction of a conversion program would be very very helpful.
