JSON to Excel — Export Arrays and Nested Objects to Spreadsheets

Got a JSON array from an API and need to share it in a spreadsheet? Paste it here and download an Excel-compatible file in seconds. Each object in the array becomes a row. Each unique key across all objects becomes a column header — so sparse objects don't lose their fields.

Nested objects are flattened with dot-notation keys (e.g. user.address.city becomes the column header user_address_city). The output is a native .xlsx-compatible SpreadsheetML file that opens correctly in Microsoft Excel, Google Sheets, and LibreOffice Calc without any import settings.

❓ Frequently Asked Questions
