Frequently asked questions

Nested JSON flattening uses dot notation to simplify complex data structures. Array-to-row mapping ensures that multiple values are organized correctly. Null or undefined values are represented as empty cells. Our tool also supports UTF-8 BOM (Excel TR character) encoding.
