Common uses
- Review API results in a spreadsheet
- Export records for nontechnical colleagues
- Create a quick CSV download from JSON
Formats and limits
- The input must be an object or an array of objects. Columns include every key, in first-seen order; strings are escaped as CSV fields.
- Nested arrays and objects are serialized as JSON in a cell. A missing field becomes empty; a JSON null becomes the literal text null. A reverse conversion does not restore the original JSON types.
- Duplicate object keys and numbers that would lose precision are rejected. Encode long identifiers and exact decimal values as strings.
