Convert XML to JSON online for free with weFixPDF. This tool helps developers, students, analysts and integration teams turn XML documents, API responses, feeds and configuration data into clean JSON. It is useful when XML data needs to be used in JavaScript, APIs, frontend apps, testing tools, data pipelines or documentation. Paste your XML, convert it, review the JSON structure and download the result without installing software or creating an account.
How to Convert XML to JSON
Paste XML and download JSON in seconds — browser-only, no data sent anywhere.
Paste or upload your XML
Enter an XML document in the input panel or upload a .xml file. The converter checks for well-formedness before parsing.
Automatic JSON mapping
Elements map to JSON object keys, attributes map to @ prefixed keys, and repeated elements become arrays. Text content maps to a # text key when mixed content is present.
Copy or download
Click Copy or Download as .json. Use the result directly in your JavaScript, Python, or any language that consumes JSON.

What This Tool Helps You Do
Convert XML into JSON when you need older XML data to work with modern apps, APIs, scripts or developer tools. XML is still common in legacy systems, feeds, exports and enterprise integrations. JSON is easier to use in JavaScript, API testing, frontend development and many data workflows.
This converter helps you move XML data into a JSON-friendly structure without manually rewriting tags into objects and arrays.
When XML to JSON Is Useful
XML to JSON conversion is useful when the source data comes from an XML feed, old API response, import file, sitemap-like structure, configuration export or enterprise system, but the next step expects JSON.
It also helps during debugging. Seeing XML as JSON can make nested data easier to inspect, especially when you want to understand which elements repeat, which values are attributes and how the document is structured.
Quick Definition
An XML to JSON converter changes XML elements into JSON keys and values. Nested XML becomes nested JSON, repeated tags often become arrays, and attributes are preserved in a JSON-readable form.
Practical Ways to Use This Tool
- Convert XML API responses into JSON for app development
- Turn XML feeds into JSON for easier inspection
- Prepare legacy XML data for modern workflows
- Convert XML files before importing them into JSON-based tools
- Review nested XML as structured JSON objects
- Transform repeated XML nodes into JSON arrays
- Convert XML attributes into a usable JSON structure
- Prepare sample JSON from XML for documentation or testing
- Debug integration data without writing a custom parser
- Move data between XML-based and JSON-based systems
What to Check Before Using the JSON
XML and JSON do not model data in exactly the same way. XML has attributes, namespaces, text nodes and repeated elements. JSON has objects, arrays and values. After conversion, review how attributes are represented and whether repeated tags became arrays correctly.
If your XML uses namespaces or schema-specific rules, check the converted JSON carefully before using it in a production workflow.
For Developers and Integration Workflows
This tool is useful for quick conversion, payload inspection and migration work. It can help bridge XML-based systems with JSON-based tools, but production usage still needs validation.
If the JSON output will be used in code, an API request or a data import, review the structure, test it with the target system and confirm that attribute names, arrays and empty values are handled correctly.
Expert Tips
- Start with well-formed XML before converting
- Fix missing closing tags or unescaped characters first
- Check repeated XML elements because they may become arrays
- Review attributes separately from child elements
- Watch namespaces if the target system depends on them
- Validate the JSON before using it in code
- Keep the original XML as a reference copy
- Compare converted outputs with a text diff checker when debugging changes
- Use JSON Formatter after conversion if you need cleaner output
- Test converted JSON with real consuming systems before relying on it
Common Mistakes to Avoid
- Assuming every XML structure maps perfectly to simple JSON
- Ignoring XML attributes that carry important data
- Missing repeated elements that should become arrays
- Forgetting that XML namespaces may matter to the original system
- Converting malformed XML and expecting reliable JSON
- Treating empty XML tags and missing values as the same thing
- Copying generated JSON into production without testing it
- Deleting the original XML before verifying the JSON output
- Assuming a valid JSON result means the data model is correct
- Overlooking text nodes mixed with child elements
Helpful Next Steps
After converting, format the JSON before using it in code or sharing it with teammates. If the XML came from an API, test the converted structure against the actual consumer. If you need to go back the other way, use JSON to XML. If you are comparing two converted outputs, use a text diff checker to spot structural changes.

Frequently Asked Questions
How do I convert XML to JSON online?
Paste your XML into the input area, run the conversion, then copy or download the generated JSON output.
What is XML to JSON conversion used for?
It is used when XML data needs to be consumed by APIs, JavaScript apps, testing tools, data workflows or systems that prefer JSON.
Can the converter handle nested XML?
Yes. Nested XML elements can be represented as nested JSON objects, but you should review the output structure before using it.
How are XML attributes converted to JSON?
Attributes are usually mapped into special JSON keys or grouped with the element value. Review the output if your target system expects a specific attribute format.
How are repeated XML tags handled?
Repeated sibling tags are usually represented as JSON arrays so multiple matching elements are not overwritten.
Why does my XML fail to convert?
XML must be well-formed. Common issues include missing closing tags, mismatched tag names, unescaped ampersands and invalid characters.
Can I convert XML API responses to JSON?
Yes. This is useful when testing integrations, adapting XML responses for JavaScript or preparing data for JSON-based workflows.
Can I convert JSON back to XML?
Use the related JSON to XML converter when you need to convert JSON data back into XML format.
What should I check after conversion?
Check attributes, repeated elements, text nodes, namespaces, empty values and whether the JSON structure matches your target application.
Is this useful for developers?
Yes. Developers often use XML to JSON conversion when modernizing integrations, testing payloads or working with legacy XML data in JSON-based tools.
