    The details

    What happens when you convert between data formats

    JavaScript Object Notation. The default way machines exchange structured data. The data is parsed into a structure and written back out in the target format — a flat table becomes nested objects, or vice versa. The result is a extensible markup language. a structured, self-describing cousin of html, produced entirely inside your browser.

    What survives

    • Every value
    • The relationships, wherever the target format can express them

    What changes

    • The shape of the data, which is the point of the conversion
    • The order of keys, which is not guaranteed to be preserved

    Where it goes wrong

    • JSON to CSV only makes sense for a flat list of objects — anything nested is flattened or lost
    • XML has no standard for a list of items, so the same file can parse into different structures in different tools

    Why anyone would do this

    Every system wants a different shape, and reshaping by hand is where mistakes happen.

    About the format

    JavaScript Object Notation.

    Text made of objects, arrays, strings, numbers, booleans and null, with a syntax borrowed from JavaScript but with no code in it.

    Where it is good
    • Readable as well as parseable
    • Maps almost exactly onto objects in every major language
    • Strict about its types, so mistakes surface immediately
    Where it falls short
    • No comments
    • No way to refer to the same piece of data twice
    • Not for very large files — the whole thing is usually held in memory
    You will find it on
    Web APIs, config files, data pipelines, every modern app

    The thing people miss

    JSON has no trailing commas and no comments, which is the two things people try to add to it most often — and which break every strict parser.

    About the target

    Extensible Markup Language.

    A tree of elements with attributes and text, defined by a schema. It is verbose, but every node is explicitly named and closed.

    • Self-describing and self-validating
    • Comments are allowed
    • Deeply entrenched in enterprise, government and publishing systems

    How to

    JSON to XML, step by step

    1. 01

      Add your json data

      Drag the file onto the drop zone, or tap to browse. Only one file is needed.

    2. 02

      Choose the XML settings

      Set the XML-specific options — everything happens locally, so the speed is your device, not a queue.

    3. 03

      Download the result

      The finished XML downloads to your device. Nothing is uploaded and nothing is retained.

    Questions

    JSON conversion questions

    What actually happens to my JSON file when I convert it to XML?

    The data is parsed into a structure and written back out in the target format — a flat table becomes nested objects, or vice versa. So the JSON file is unpacked, the content is laid out, and the result is written out as XML. Every value survives unchanged.

    Will converting JSON to XML reduce the quality?

    For this particular conversion, not in the way you would expect. Every value — the JSON content is not re-encoded in a lossy way. The only thing that changes is the format it is stored in.

    Is my JSON file uploaded to a server?

    No. This JSON to XML conversion runs as JavaScript inside your browser tab. The file is read from your device and the result is written back to your device, so there is no upload step, no file-size limit and no copy of your JSON file on any server.

    Do I need an account or will there be a watermark?

    Neither. There is no sign-up step, no email capture and no watermark on the output. The only limits are the ones your own device imposes.

    What is the most common mistake people make when converting JSON to XML?

    JSON to CSV only makes sense for a flat list of objects — anything nested is flattened or lost

    Why would somebody convert JSON to XML at all?

    Every system wants a different shape, and reshaping by hand is where mistakes happen. In short: an api response you want to look at properly

    Something most people do not know about JSON?

    JSON has no trailing commas and no comments, which is the two things people try to add to it most often — and which break every strict parser.
