FAQ
Questions, answered.
What JSON shape does this converter expect?＋
Use an array of objects, for example [{"name":"Ada","role":"developer"}]. Nested objects are stringified as values rather than flattened into extra columns.
What happens when objects have different keys?＋
The output includes the union of all keys. Missing values are left empty in the corresponding row.
Can I open the result in Excel or Sheets?＋
Yes. The result is standard comma-separated text, although regional spreadsheet settings may expect a different delimiter.
