I was a Coda fan from day one. Love at first sight, as they say.
However, the real power of the formula language was most clear after translating an Excel doc into Coda:
As I noted in the post at the time:
Neither of these are simple, but you don’t have the slightest chance of understanding the first one and I’ll bet you can figure out what the second one does.
Always felt afterward that if the world were to have had the Coda formula language to power Excel we would have saved billions maybe trillions of dollars of wasted time from so many inscrutable formulas in fragile docs.
