About Excel to JSON
- What does Excel to JSON do?
- Read a spreadsheet sheet into a JSON array of objects.
- Who is it for?
- Analysts and operations teams moving data between systems, developers who need a quick format conversion, and anyone whose CSV keeps breaking when Excel opens it.
- Is it free?
- Yes. Excel to JSON is free with no account, no watermark on your output, no daily cap and no trial period. Because it runs on your own device it costs us nothing to run, which is why there is no catch.
- Is it safe to use with confidential files?
- Yes, and not because we promise to behave. Excel to JSON never sends your file anywhere — the work happens in your browser. There is no upload, so there is no copy of your document in our systems at any point.
- What file formats are supported?
- Input: XLSX, XLS, XLSM. Output: JSON.
