Frequently asked questions
What structure must the JSON have?
- The JSON should be an array of objects, where each object represents one row of data.
What happens if some objects have different keys?
- The converter collects the union of all keys for the header row; missing fields in individual objects become empty cells.
How are cells with commas or quotes escaped?
- Following RFC 4180, fields containing commas, quotes, or newlines are wrapped in double quotes, and internal quotes are doubled ("").
Can it handle nested JSON objects?
- Yes, nested properties are either stringified or flattened using dot notation.
Is my data sent to any third-party server?
- No, all conversion and file generation happens locally inside your browser tab.
Can I open the resulting CSV in Microsoft Excel?
- Yes, the output is fully compliant with Microsoft Excel, Apple Numbers, and Google Sheets.
