JSON to XML Converter
Paste JSON, pick a root tag, and get clean indented XML in a second â right inside your browser.
Works with objects, arrays, nested structures, numbers, booleans and null values. Nothing is uploaded anywhere.
XML Output
How to Use This JSON to XML Converter
- Paste your JSON. Drop in an API response, a config file, or a single object. Arrays at the top level are fine too.
- Name the root element. XML needs exactly one outer wrapper. Use something descriptive like order, response or catalog instead of the default.
- Pick your formatting. Two spaces reads well in editors, four suits legacy enterprise styles, and no indent gives you the smallest payload.
- Decide on the declaration line. Keep it if the XML will be saved as a file; skip it if you're pasting the block inside a larger document.
- Hit Convert to XML. The result shows instantly along with element and character counts.
- Copy or download. Grab it to your clipboard, or save it as a text file for later.
Key Features
Instant Browser Conversion
Everything happens locally in JavaScript. No upload, no waiting on a server round trip, no queue.
Deep Nesting Support
Objects inside arrays inside objects convert recursively, and every level keeps correct indentation.
Safe Tag Names
Keys with spaces, dots or leading digits are cleaned into valid XML element names automatically.
Entity Escaping
Ampersands, angle brackets and quotes inside values become proper XML entities so parsers never choke.
Output Stats
See element count, depth and character length right below the result to gauge payload size.
Mobile Friendly
Large touch targets and a scrollable output panel make it usable from a phone during on-call debugging.
How the Conversion Logic Works
JSON and XML describe data differently, so a converter has to make a few sensible decisions. Here's exactly what this one does.
Objects become nested elements. Every key turns into a tag and its value becomes the tag's content. {"city":"Pune"} becomes <city>Pune</city>.
Arrays become repeated siblings. XML has no array type, so the standard workaround is repetition. A key called items holding three entries produces an <items> wrapper containing three <item> children. The child name is the singular form of the parent when it ends in "s", otherwise the tool falls back to <item>.
Primitives are written as text nodes. Numbers keep their exact literal form, booleans print as true or false, and null becomes a self closed empty element such as <note/> so the field still exists in the structure.
Names get sanitised. XML forbids spaces, most punctuation and a leading digit in element names. Spaces convert to underscores, illegal characters are dropped, and a numeric first character gets an underscore prefix. A key like "2nd address" safely becomes <_2nd_address>.
Values get escaped. Five characters are replaced before output: & becomes &, < becomes <, > becomes >, double quote becomes " and apostrophe becomes '. That single step prevents the majority of malformed XML bugs.
Because the whole routine is recursive, the depth of your data doesn't change the approach â the same four rules apply at level one and level twenty.
Practical Examples
1. Indian e-commerce order feed
A Shopify store in Surat exports orders as JSON, but its GST accounting software only ingests XML. Converting the payload keeps the same field names while satisfying the importer.
{"order":{"id":"SD-2291","state":"Gujarat","total":4599.5,"cod":false}}
â
<root>
<order>
<id>SD-2291</id>
<state>Gujarat</state>
<total>4599.5</total>
<cod>false</cod>
</order>
</root>2. Courier tracking integration
An Indian logistics partner in Delhi accepts manifests only in XML. The warehouse system speaks JSON. One paste bridges the gap without writing a script.
{"shipments":[{"awb":"DL9911","pin":"110045"},{"awb":"DL9912","pin":"400072"}]}
â
<shipments>
<shipment>
<awb>DL9911</awb>
<pin>110045</pin>
</shipment>
...
</shipments>3. RSS-style content block
A publisher in Berlin pulls article metadata from a headless CMS as JSON and needs an XML fragment for a syndication feed. Skipping the declaration lets the block sit inside an existing feed file.
{"item":{"title":"Q3 Report","author":"M. Braun","words":1840}}4. Legacy bank statement import
A finance team receives statement data as JSON from a fintech API but their decades-old reconciliation tool reads XML only. Four space indentation matches the old templates their team already reviews by eye.
What Is a JSON to XML Converter?
A JSON to XML converter takes structured data written in JavaScript Object Notation and rewrites it as Extensible Markup Language without changing the meaning. JSON is compact and dominant in modern APIs. XML is verbose but still runs enormous parts of banking, government, healthcare, publishing and enterprise integration. When those two worlds meet, somebody has to translate â and doing it by hand is slow and error prone.
This tool does the translation in your browser. You keep the same field names, the same nesting, the same values. What changes is the syntax: braces become tags, arrays become repeated elements, and text gets escaped. It's the fastest way to hand a JSON-native system's output to an XML-native system's input.

Frequently Asked Questions
Is this tool free to use?
Yes, basic usage is available at no cost. Free users can run the tool a set number of times per day. Registered users and Pro members get higher daily limits and character allowances. The core feature works exactly the same for everyone.
Does my JSON data leave my browser?
No. The conversion runs entirely in your browser using JavaScript. Your JSON is never uploaded to a server, which makes the tool safe for API payloads and internal data samples.
What happens to JSON arrays?
Each array item becomes a repeated child element. An array named items produces multiple item elements inside an items wrapper, which is the standard XML pattern for lists.
How are invalid XML tag names handled?
Keys with spaces, symbols or a leading digit are cleaned automatically. Spaces become underscores, illegal characters are stripped, and names starting with a number get an underscore prefix so the XML stays well formed.
Are null and boolean values supported?
Yes. Booleans are written as true or false, numbers keep their exact value, and null becomes an empty self closed element so the structure is preserved.
Does it escape special characters?
Yes. Ampersands, angle brackets and quotes inside values are converted to XML entities so the output parses correctly in any XML reader.
Can I convert deeply nested JSON?
Yes. Nesting is handled recursively, so objects inside arrays inside objects all convert correctly with proper indentation at every level.
Why do I see a JSON parse error?
The most common reasons are trailing commas, single quotes instead of double quotes, unquoted keys or a missing closing bracket. The error message shows the position so you can fix it quickly.
Can I add XML attributes instead of child elements?
Not automatically. JSON has no attribute concept, so every key becomes an element. If your schema needs attributes, convert first and then adjust the specific tags in your editor.
Can I use the XML output in production?
Yes. The output is standard UTF-8 XML. Validate it against your schema or DTD if your system requires one, since a generic converter cannot know your namespace rules.
What if my JSON has duplicate keys?
JSON parsers keep only the last occurrence of a duplicate key, so the XML will contain that final value. Rename the keys in your source if you need both.
Does it work on mobile?
Yes. The layout adapts to small screens and the buttons are sized for touch, so you can convert data from a phone or tablet.
