Method

Data conversion method

Input is parsed as structured data rather than changed with search-and-replace rules. CSV quoting, JSON types, XML nodes, YAML syntax, URL encoding, and JWT base64url segments are handled according to their relevant parser model.

Conversions run locally and preserve data types where the destination format permits. Review nested structures, namespaces, comments, special tags, and spreadsheet conventions when moving between formats with different capabilities.

Questions

JSON to CSV Converter FAQ

Can nested JSON be converted?

Nested values are serialized as compact JSON inside a cell. Restructure deeply nested data first when separate spreadsheet columns are required.

How are CSV columns chosen?

The exporter uses the union of top-level keys found across all input objects so later records do not silently lose fields.
