JSON to Excel FAQ
Can I open the CSV directly in Excel?
Yes! The generated CSV file opens directly in Microsoft Excel, Google Sheets, LibreOffice Calc, and any other spreadsheet application.
How are nested objects handled?
With flattening enabled, nested objects become dot-notation columns (e.g., address.city). Without flattening, they are serialized as JSON strings.
Is my data secure?
Yes! All conversion happens in your browser. Your data is never sent to any server.
