Your files stay yours

Files are converted inside your browser. They are never sent to a server and we don’t keep any copy. Everything is wiped from memory when you clear the list or close the tab.

How It Works

  1. 1

    Drop your JSON files, choose them or paste them.

  2. 2

    They are converted to Excel automatically, right on your device.

  3. 3

    Download them one by one or all together in a ZIP.

What is JSON?

JSON is the most common format for exchanging data between apps and APIs. To become a spreadsheet or CSV, it must be a list of records with the same fields.

What is Excel?

XLSX is the Microsoft Excel workbook format since 2007. When converted, each sheet keeps its values; charts, macros and formatting are not carried over.

Questions

Does converting JSON to Excel lose quality?
No data is lost: every value is kept. What doesn’t exist in Excel isn’t carried over, like formulas (their result is kept), colors, charts or merged cells.
Do you store my files?
No. Your files are never uploaded, so there is nothing for us to store. They only exist in your browser’s memory while the page is open and are deleted when you remove them, clear the list or close the tab. We only count anonymous usage, like how many conversions happen, never file names or contents.
Is it safe?
Yes. Your files are converted on your own device and are never uploaded to any server.
Is it free?
Yes. It’s free, with no sign-up, no watermarks and no ads.
Is there a limit?
We don’t set any limit on the number or size of files. Since everything happens on your device, its memory is the real limit: on a computer, 100-megapixel photos, 300-page PDFs and long videos convert without trouble. Phones have less room. Video and audio use your browser’s codecs, so Chrome and Edge support the most formats. If something doesn’t work, we’ll tell you.
Does it work on my phone?
Yes, in any modern browser on iPhone, Android or desktop.
