Notes

The first CSV row is treated as the header and becomes the object keys. Fields wrapped in double quotes may contain the delimiter and line breaks; a quote inside a quoted field is written as two quotes (""). Going the other way, keys from all objects are collected so rows with missing fields still line up. Both directions run locally, so it is fine for exports containing private data.
