Convert JSON arrays to .xlsx spreadsheets with automatic column detection and nested object flattening. Runs entirely in your browser.
In short: A JSON to Excel converter turns a JSON array of objects into a spreadsheet — each object becomes a row, each key becomes a column. RealJSON's converter does this in your browser with automatic column mapping and dot-notation flattening for nested fields, then downloads a ready-to-open .xlsx file.
Exporting JSON data to Excel is a common task for analysts, project managers, and anyone who needs to share structured data with non-technical stakeholders. RealJSON's free JSON to Excel converter does it in one click — no server, no macros, no installation needed.
Paste a JSON array (an array of objects) and click Convert. Each object becomes a row in the spreadsheet, each key becomes a column header, and the result downloads as a standard .xlsx file.
Column names come directly from the JSON keys. If objects in your array have different sets of keys, the converter unions all keys across the entire dataset to create a complete column set — no data is lost.
Deeply nested JSON values are flattened into readable column names using dot notation — for example, {"user": {"name": "Jane"}}} becomes a column named user.name. This makes complex JSON directly usable in Excel without manual preprocessing.
Paste a JSON array of objects and click Convert. Each object becomes a row, each key becomes a column header, and the result downloads as a standard .xlsx file.
The converter unions all keys across the dataset to build a complete column set, so nothing is lost — objects missing a key just get an empty cell there.
Nested values are flattened into readable column names with dot notation — e.g. { "user": { "name": "Jane" } } becomes a column named user.name.
A standard .xlsx file compatible with Microsoft Excel, Google Sheets, LibreOffice Calc, and Apple Numbers.
No. The .xlsx file is generated entirely in your browser — your JSON never leaves your device.
To go the other direction, the CSV to JSON converter turns spreadsheet exports back into JSON. Use the JSON Viewer to inspect your data before converting, or the JSON Validator to confirm it's valid first.
