How it works

CSV is parsed following RFC 4180: fields can be quoted, contain the delimiter or line breaks, and escape quotes by doubling them. Commas, semicolons and tabs are detected from the header row.

When converting JSON to CSV, every key found in any object becomes a column, and nested values are written as JSON text.
