What is the XML to JSON Converter?

The XML to JSON Converter is a client-side format utility designed to convert Extensible Markup Language (XML) tags into JavaScript Object Notation (JSON) objects. By pasting your XML code directly into the browser tab, you can translate legacy data hierarchies into modern developer-friendly formats.

This tool uses browser parsing algorithms to read XML tags recursively, extracting tag structures and nesting levels. Because all parsing and syntax translations are processed in browser RAM, your proprietary database layouts, system configs, and API responses are never uploaded or stored.

How to Use the XML to JSON Converter

  1. Paste Your XML: Input your raw XML text into the left textarea labeled "XML Input".
  2. Convert Your Data: Click the "Convert to JSON" button to parse the XML hierarchy.
  3. Inspect the Output JSON: Review the formatted, indentation-spaced JSON string in the right textarea.
  4. Copy to Clipboard: Click the "Copy JSON" button to save the converted object data directly to your clipboard for use in your applications.

Key Features

  • Recursive Node Parsing: Map deeply nested XML tag hierarchies into organized JSON objects.
  • XML Attribute Extraction: Retains metadata by saving attributes as property keys within the JSON output.
  • Error Syntax Validation: Displays warning alerts if the inputted XML tag structure is invalid or unclosed.
  • Prettified Indentation Spacing: Outputs clean, indented JSON text that is easy to read and debug.
  • 100% Client-Side Run: Performs conversions offline in browser RAM to safeguard data privacy.

Common Use Cases

  • Legacy API Migrations: Reformat XML payloads from SOAP web services into JSON for modern REST API integrations.
  • Config Manifest Audits: Convert XML configuration maps or app settings into readable JSON files.
  • Website Sitemap Processing: Translate XML sitemaps or RSS feeds into arrays of JSON links and dates.
  • Corporate Data Refinement: Parse older corporate databases or export templates into JSON for script processing.

Frequently Asked Questions

The converter parses all XML attributes (like id="123" or class="header") and nests them as property keys prefixed with an underscore or grouped under an attributes key within the JSON object.

No. 99tool.in processes all document parsing and JSON rendering locally in your browser. None of your inputs, keys, or schemas are shared or uploaded.

XML requires strict formatting. The parser will fail if there are missing closing tags, unquoted attributes, mismatched cases, or multiple root tags. Double-check your XML structure for compatibility.

We recommend using this converter for files under 5MB. Processing deeply nested tags or larger XML datasets may cause temporary browser lags during recursive loops.

Namespaces are treated as part of the tag name strings, ensuring that elements like <soap:Body> map directly to keys like "soap:Body" in the resulting JSON.

🔒 Privacy & Data Note: XML parsing and JSON conversions occur locally in your browser. No files, structures, or configurations are sent to our servers.
