JSON to XML Converter

1. Paste your JSON — Copy raw JSON from an API response, config file, or database export and paste it into the input area. You can also upload a .json file or drag & drop one directly.
2. Set the root element name — The default is root. Change it to match your XML schema (e.g., response, order, config).
3. Choose indentation — 2 spaces (most readable), 4 spaces, tab, or minified single line for production transfer.
4. Click "Convert to XML" — The tool instantly parses your JSON, builds the XML element tree with proper character escaping, and renders the result with syntax highlighting.
5. Copy or download — Click Copy to copy the XML to your clipboard, or Download .xml to save the file.

JSON and XML are the two most widely used data interchange formats on the web. JSON dominates modern REST APIs and config files; XML still powers older enterprise systems, SOAP services, RSS feeds, sitemaps, document formats (DOCX, XLSX), and a vast catalog of legacy integrations. Converting between them cleanly — without breaking element names, escaping rules, or array handling — is harder than it looks.

Our JSON to XML converter is a free, browser-based tool that handles all the edge cases so you don't have to. Built by engineers who actually integrate with legacy XML APIs every day, it produces clean, valid, parseable XML that any standard XML parser will accept on the first try:

• Configurable root element name — Match the XML schema you're targeting, whether it's <response>, <order>, <envelope>, or anything else.
• Smart array handling — JSON arrays become repeated sibling elements using the parent key as the element name — the most common and most readable mapping. Top-level arrays wrap each item in a configurable <item> element.
• Automatic name sanitization — JSON keys with spaces, special characters, or leading digits are sanitized to valid XML element names without you having to pre-process the data.
• Proper character escaping — All five XML special characters (&, <, >, ", ') in string values are escaped to their entity equivalents. Output is always valid XML.
• Self-closing empty elements — Optional self-close (<empty/> vs. <empty></empty>) for cleaner, more compact output.
• Configurable indentation — 2 spaces, 4 spaces, tab, or fully minified single line. Pick what matches your downstream consumer's expectations.
• Optional XML declaration — Include the <?xml version="1.0" encoding="UTF-8"?> header for standalone files, or skip it for XML fragments embedded in another document.
• Syntax highlighting — Tags, attributes, values, and the declaration are color-coded so you can scan the structure at a glance.

100% browser-based — your data is never uploaded to any server. All conversion runs in your browser using JavaScript. No file size limits beyond what your browser memory allows, no signup, no privacy concerns. Safe for API responses with auth tokens, internal config files, customer data, and anything else you wouldn't want passing through someone else's server.

The tool supports drag-and-drop file upload, auto-saves your draft in localStorage, and works with .json, .jsonc, .json5, and .geojson files.

• Privacy-first architecture — Many popular converters send your data to a remote server. Ours runs 100% in your browser. Your API keys, customer data, and proprietary integrations never leave your machine.
• Correct array handling — Most converters either flatten arrays into indexed children (<item0>, <item1>) or break the semantic meaning. Ours produces the idiomatic repeated-sibling pattern that real XML schemas expect.
• Real character escaping — Many free converters forget to escape ampersands or angle brackets inside string values, producing invalid XML that breaks downstream parsers. Ours handles all five special characters correctly, every time.
• Configurable, not opinionated — Root name, array item name, indent, declaration, self-closing — you control the output format. Match your schema, don't bend your schema to match the tool.
• No ads, no signup, no tracking — Clean, distraction-free interface. Paste and convert. No popups, no account requirements, no cookie banners blocking your workflow.
• Draft persistence — Your last input is saved in localStorage and restored automatically when you return. Never lose work in progress.
• Keyboard-first — Ctrl+Enter runs the conversion without reaching for the mouse. Built for developers who live in the keyboard.

• Integrating with legacy SOAP / XML APIs — Your modern app speaks JSON, but the legacy partner only accepts XML. Convert the payload before sending.
• Generating RSS / Atom feeds — Your CMS or database returns JSON, but RSS readers need XML. Convert article lists into the right structure.
• Building Office documents — DOCX, XLSX, and PPTX files are XML inside. Generate them from JSON-shaped data.
• SVG manipulation — Programmatically generated SVG content from JSON config files, then export as standalone SVG (which is XML).
• XSL transformations — Apply XSLT stylesheets to JSON-sourced data by converting to XML first, then running the transform.
• Sitemap generation — Site URL lists in JSON converted to sitemap.xml for Google Search Console submission.
• Configuration migration — Moving from JSON config files (modern Node.js, React tooling) to XML config (Maven, Spring, .NET) or vice versa.
• Enterprise data exchange — Banking, healthcare, and government systems still standardize on XML for compliance reasons. Convert JSON exports to XML for submission.
• Learning the differences — If you're new to either format, seeing the same data side-by-side in JSON and XML is the fastest way to understand how they map.
