.xml documents
XML → JSON — the fast, private way to turn XML documents into structured JSON. Drag files in below and the converter runs entirely inside your browser tab. No sign-up, no upload, no size cap beyond what your device can handle.
A dedicated xml-to-json converter is the fastest option when you need a clean .json file without installing software, signing up, or waiting for a server round-trip. Typical uses include modernizing legacy XML feeds into JSON for a web app. Because everything runs in your browser tab, you can convert one file or a whole batch on a work laptop, a shared computer, a Chromebook, or even a phone — anywhere a modern browser runs.
SwiftConvert uses well-tested open-source libraries compiled to run inside the browser. When you drop a xml file, it is parsed in memory, transformed into json, and offered back to you as a direct download. No temporary copy is written to a server, no queue, no worker cluster — the CPU doing the work is the one in front of you. That means results are usually ready in seconds for small files, and speed scales with your device rather than someone else's free plan.
For best results, start from a clean xml source: fewer nested layers, embedded fonts where possible, and reasonable file sizes convert most reliably. If a batch stalls, split it into smaller groups so the browser can free memory between runs. On mobile, close background tabs before converting very large files. If a specific JSON setting matters to you — resolution, quality, page size — check the options exposed above the drop zone; SwiftConvert exposes the knobs that actually change the output, and leaves the rest on sensible defaults.
Yes. SwiftConvert runs the XML → JSON conversion in your browser using open-source libraries. There's no server, no account, and no per-file limit.
