Remembering all the cases I needed to export to CSV – 99% are the relatively small datasets, so marginal gains in a few millisecond to import aren't worth sacrificing convenience. And sometimes you just get data from gazzilion of diverse sources, and CSV is the only option available. I suspect that not everybody here work exclusively with huge datasets and well-defined data pipelines. On a practical side, if I want to follow suggestions, how do I export to Avro from Numbers/Excel/Google Sheets?
