Conversion notes

JSON → CSV accepts an object or array of objects. Nested objects flatten to dot keys (role.title); arrays are kept as JSON strings.
CSV supports quoted fields, commas and line breaks inside quotes. The first row is the header; numbers and booleans are typed automatically.
URL encoding uses encodeURIComponent — meant for a single component (query value, path segment), not a whole URL.
Base64 uses UTF-8. Encoding is not encryption.
