Add your JSON file
Drop one or more .json files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
JSON to XML
Restructuring .json data as .xml changes the serialization without touching the values themselves. Free, private, and validated — the file never leaves your browser.

Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.About converting JSON data to XML data
Restructuring .json data as .xml changes the serialization without touching the values themselves. A .json file holds JavaScript Object Notation: nested objects, arrays, strings, numbers, booleans, and null written in a strict text syntax. It is the default data language of the web — most APIs speak nothing else.
An .xml file contains Extensible Markup Language: angle-bracketed tags you define yourself, arranged in a strictly nested tree. It is a meta-format — RSS feeds, SVG images, and Office documents are all XML underneath. For this route the practical draw is rigorous validation against formal schemas and namespaces support mixing vocabularies safely — balanced against verbose — every element name is written twice, which is worth knowing before you commit a large batch.
Why convert JSON to XML?
The practical trigger for this conversion is usually a mismatch: with .json, no comments — a perpetual annoyance for configuration files. Switching to .xml buys you rigorous validation against formal schemas, which is why it is the better fit for build and platform configuration (Maven POMs, Android manifests). Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
JSON vs XML at a glance
| Aspect | JSON data (.json) | XML data (.xml) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | exactly six value types; no dates, no comments, no trailing commas — the strictness is deliberate | well-formedness is binary: one mismatched tag makes the document invalid, and conforming parsers must reject it |
| Strongest at | rEST and HTTP API request and response payloads | build and platform configuration (Maven POMs, Android manifests) |
| Weak spot | no comments — a perpetual annoyance for configuration files | verbose — every element name is written twice |
Pick XML as the output
Select .xml in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if XML is selectable, the route is real and validated.
Convert on your device
Press Convert. The restructuring is plain local parsing — your data is never posted to a server for processing.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid XML file. Outputs keep the original filename with the .xml extension.
JSON to XML questions, answered
Will converting JSON to XML lose quality?
There is no visual quality to lose — json is text-oriented and xml is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Is it private to convert JSON files here?
Yes — the .json file is processed inside your browser tab and never uploaded. The restructuring is plain local parsing — your data is never posted to a server for processing. Close the tab and the file is gone from memory.
Where will the XML file work?
Parsers exist in every programming language, browsers display raw XML as an expandable tree, and dedicated editors validate against schemas as you type. Operating systems treat it as plain text otherwise.
Will the XML file be bigger or smaller than my JSON?
It depends on the content: well-formedness is binary: one mismatched tag makes the document invalid, and conforming parsers must reject it. Convert one representative file first and compare before batch-processing a large set.
Can I convert XML back to JSON?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .json → .xml → .json is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
