JSON to Excel conversion turns structured JSON into rows and columns that spreadsheet tools can open. JSON is often nested, while Excel expects a rectangular table, so the converter can flatten objects like customer.name into dot-notation columns and join arrays into readable cell values.
The default download is an Excel-compatible .xls file built from an HTML table, which opens cleanly in Excel, LibreOffice, and many spreadsheet viewers. You can also switch to CSV when you want a plain-text export for imports, scripts, or data pipelines.
How to Use JSON to Excel Converter
Paste a JSON array, object, or API response into the input panel.
Keep nested flattening enabled for spreadsheet-friendly columns.
Choose Excel .xls or CSV output.
Review the table preview for row and column shape.
Download the spreadsheet or copy the generated output.
Common Use Cases
- Export API responses into Excel for reporting and stakeholder review.
- Convert JSON test fixtures into tabular QA review sheets.
- Flatten nested order, customer, or product records for spreadsheet analysis.
- Create CSV imports from JSON arrays without writing a script.
- Turn small JSON datasets into spreadsheet attachments for non-technical teammates.
Example Input and Output
A JSON array with a nested customer object becomes a spreadsheet table with dot-notation columns.
[ { "orderId": "SO-1001", "customer": { "name": "Alice" }, "total": 248.5 } ]orderId,customer.name,total\nSO-1001,Alice,248.5Privacy
Your JSON data never leaves the browser. Downloads are generated locally.
Excel format
Use CSV for simple imports and the Excel .xls option when you want an easy spreadsheet download with a readable table structure.
Frequently Asked Questions
Does this create a real .xlsx file?
The default export is an Excel-compatible .xls HTML workbook. It opens in Excel and spreadsheet apps, but it is not a zipped .xlsx workbook.
What JSON shape works best?
An array of objects works best. A single object exports as one row, and a top-level object containing an array will use that nested array when possible.
How are nested objects handled?
With flattening enabled, nested values become dot-notation columns such as customer.name. With flattening disabled, nested values are stored as JSON strings in a cell.
How are arrays handled?
Array values inside records are joined with a pipe separator. Arrays of objects are stringified so the cell still keeps the source data.
Is my JSON sent to a server?
No. JSON parsing, table generation, and file creation run locally in your browser.
