“Typical process latency: Someone copies and pastes data from a thing into another thing”[1]. Jokes aside, though, I don’t think it’s fair to criticise people for using the only user-accessible interapplication communication channel the industry has universally agreed to make work and not use as lock-in leverage.

The spreadsheets being in different formats and lacking additional sheets that’d automatically reformat the data the way the next step needs is something I’d criticise, but I undertstand how that might be nonobvious if you aren’t lazy enough to think about automating everything you possibly can.
