Finally getting into the 20th century and setting up an electronic flight log. Still going to keep my old school paper ASA-SP-30 (circa 1993) pilot log, because two is one, one is none. But having the information input electronically is useful too. And what kind of flying geek would I be if I didn't have a digital version of my logbook? Exactly. So I'm using MyFlightbook.com and their iPad/iPhone apps, but inputting ~18 years of flight records using their interface (web or app) was going to be too tedious. Fortunately, they have a CSV import feature. Naturally, I ‘reverse engineered’ my own Excel worksheet (based on a downloaded export of a few records I input using the app), before checking and learning that, of course, in fact, they provide their own CSV “ template ” and description of the columns and data they expect . Alright, back to data entry.
