Here are detailed answers to the most common questions about the JSON to CSV Converter:
Any valid JSON is supported. Arrays of objects work best (each object becomes a row). Single objects are wrapped in an array. Nested objects can be flattened into dot-notation columns using the 'Flatten nested' option.
With flatten enabled, a nested object like {"user": {"name": "Alice"}} becomes a column named user.name. This works for any depth of nesting. Arrays within objects are kept as stringified values.
Use comma for most applications (Excel, Google Sheets default). Use tab for TSV files. Use semicolon if your data contains commas (common in European locales). Use pipe if your data contains both commas and semicolons.
Yes. Values containing the delimiter character, double quotes, or newlines are automatically wrapped in double quotes and escaped according to RFC 4180 CSV specification.
The converter collects all unique keys across all objects and uses them as column headers. Objects missing a key will have an empty cell in that column.
Completely. All conversion happens in your browser using JavaScript. No data is sent to any server — your JSON never leaves your device.
