Convert JSON to XML

Free, no login, and your file never leaves your device.

Open the XML ↔ JSON tool

JSON to XML, converted on your own machine

Converting JSON to XML normally means handing your file to a website that uploads it, processes it on a machine you cannot inspect, and asks you to trust a retention paragraph. FileForge removes that step: the XML ↔ JSON tool runs inside this browser tab, so a JSON file becomes XML without ever crossing the network.

Convert XML documents into structured JSON — attributes included — and turn JSON back into well-formed, indented XML. Everything happens locally in your browser: nothing is uploaded, stored, or logged.

Because the conversion happens on your hardware, throughput depends on your CPU rather than a shared free tier — there are no file-size caps, no watermarks, no daily quotas, and no paid tier that unlocks the real feature set. It also means the page keeps working offline in the browser once loaded, which is handy for confidential material on a locked-down laptop or a phone in aeroplane mode.

How to convert JSON to XML

  1. 1

    Open XML ↔ JSON

    Open the XML ↔ JSON page on FileForge. No sign-up, install, or extension is needed — the tool loads as a normal web page.

  2. 2

    Add your file

    Paste or drop your file into the panel, or click to browse. The file is read locally in your browser and is never uploaded.

  3. 3

    Choose your settings

    Adjust the options in the settings panel — convert between xml and json — until the result matches what you need.

  4. 4

    Run and download

    Press the action button, wait for processing to finish on your own CPU, then download the result straight from the page.

JSON to XML — frequently asked questions

Do I need to create an account to use XML ↔ JSON?
No. FileForge requires no sign-up or login — just open the tool and use it.
Is XML ↔ JSON really free?
Yes, completely free with no hidden limits or premium paywall.
Does XML ↔ JSON upload my file to a server?
No. Everything runs locally in your browser. Your file is never uploaded, stored, or transmitted anywhere.
Is there a file size limit?
There is no artificial limit. The practical ceiling is your device's available memory, so very large files work best on a desktop browser with plenty of free RAM.
Does XML ↔ JSON work offline in the browser?
Once the page (and, for audio and video, the FFmpeg engine) has loaded, the tool keeps working without a network connection because all of the processing code already lives in your browser.
Is XML ↔ JSON private enough for confidential documents?
Yes. Because the file is processed on your own CPU, contracts, medical scans, ID photos and payroll data never travel over the network — you can verify that with your browser's network tab open.
Which browsers are supported?
Any modern browser with WebAssembly support — Chrome, Edge, Firefox, Safari, and their mobile versions. No plugins or extensions are required.
