About JSON and Excel

JSON is the standard data format of web APIs and JavaScript apps. It can hold nested objects and lists.

Excel is the Microsoft Excel workbook format (.xlsx), also opened by Google Sheets, Numbers and LibreOffice.

Frequently asked questions

How do I convert JSON to Excel?

Paste your JSON data into the Input box or open a file. The Excel result appears instantly on the right — copy it or click Download.

Is my data uploaded anywhere?

No. FileCrafty converts the data inside your browser, so customer lists, exports and API keys never leave your device. It also works offline once the page is open.

How is nested data turned into columns?

Nested objects become columns with dotted names such as address.city, and simple lists are joined with “; ”. If the records are inside a property (for example {"data": [...]}), that list is found automatically.

Does it accept JSON Lines (one object per line)?

Yes. Files with one JSON object per line (.jsonl / NDJSON) are read as a list of records.

Is there a size limit?

There is no fixed limit — files of tens of megabytes work fine on a computer. Very large files are not shown in the text box, but they are still converted in full.

Is it free?

Yes — free, unlimited and without sign-up.
