JSON to CSV Converter
Convert JSON arrays to CSV online with automatic column detection, straight in your browser
JSON to CSV Tips
- The input must be a JSON array of objects; each object becomes one CSV row.
- Columns are collected in order of first appearance, so objects with different keys are fine - missing values become empty cells.
- Fields containing the delimiter, quotes, or line breaks are automatically wrapped in quotes per RFC 4180.
- Choose semicolon as the delimiter if you will open the CSV in Excel with European regional settings.

Converting JSON to CSV by hand is tedious and error-prone: keys drift between records, values contain commas and quotes, and spreadsheets expect strict RFC 4180 quoting. This converter handles all of it - it flattens an array of JSON objects into rows, unions the keys into a stable column order, and escapes every field correctly so the result opens cleanly in Excel, Google Sheets, and pandas.

Vanlige spørsmal
Vanlige spørsmal om Json To Csv-formatering besvart
Yes, completely free with no registration or file size throttling. All conversion happens locally in your browser.
An array of objects (each object becomes a row, keys become the header) and an array of arrays (each inner array becomes a row). A single object or any other top-level type is rejected with a clear message.
Objects do not need identical keys: the converter takes the union of all keys in order of first appearance, and missing values become empty cells. Nested objects and arrays are serialized as JSON strings in their cell rather than silently dropped.
Most likely a delimiter mismatch: Excel with European regional settings expects semicolons. Switch the delimiter to semicolon and convert again. If punctuation is garbled, that is an encoding issue on export - this tool outputs standard UTF-8.
No. The parser is plain JavaScript running on this page. Nothing is transmitted, logged, or stored.
