How do I convert JSON to CSV?

Convert a JSON array of objects to CSV locally. Nested objects and arrays become columns using dot and bracket paths, such as user.name and tags[0]. Literal dots, brackets, and backslashes in keys are backslash-escaped to keep every column unambiguous. Null values and missing keys become empty cells; booleans and numbers stay unquoted.
