What It Does

Convert XML to JSON instantly in your browser.

Nextooly’s XML → JSON Converter helps developers and API integrators quickly transform XML into clean, readable JSON—without sending any data to a server. Paste XML or upload a .

xml file, then generate well-structured JSON with configurable indentation and optional attribute handling. The tool uses DOMParser in your browser to safely parse XML and convert elements, attributes, and repeated tags into intuitive JSON objects and arrays.

Example

Input: A XML file or pasted xml content you want to transform.

Output: A JSON result you can download, copy, or reuse immediately.

Best For

People who need to convert XML to JSON quickly without installing software.
Convert a legacy XML API response into JSON for use in a modern JavaScript application.
Migrate XML configuration files to JSON for tools like webpack.
Inspect and debug XML payloads by viewing them in a JSON-friendly format.
Transform SOAP response bodies for REST client consumption.
Not ideal for: heavily malformed data that needs scripting or deeper cleanup first.

Key Features

Runs entirely in your browser for a private, on-device workflow.
Keeps files and text on your device with no server upload step.
Lets you export or download the finished result right away.
Handles structured data settings such as delimiters, headers, flattening, or pretty printing.
Supports JSON-friendly workflows when structured data needs a cleaner view.
No signup or installation required for the core workflow.

Pricing

Plan type: Free
Price: $0
Limits: Great for quick browser tasks; automated pipelines and very large payloads may need local scripts or APIs.

Pros

Keeps sensitive input on your device.
Includes practical controls for common real-world inputs.
Produces output you can use immediately.

Cons

Results can vary based on browser permissions and which web APIs your device exposes.
Advanced automation or team-wide workflows may still need desktop software or APIs.

FAQ

Does this XML to JSON tool upload my data?

No. All XML parsing and JSON generation happens entirely in your browser using DOMParser. Nothing is sent to any server.

Why is my XML showing an 'Invalid XML' error?

This occurs when the XML contains syntax errors or unclosed tags. The DOMParser returns a parsererror node, which the tool detects and reports.

How are XML attributes handled?

If enabled, attributes are included under an `_attributes` object. Otherwise, they are ignored to keep the JSON clean.

How are repeated XML tags represented?

Repeated sibling tags are converted into arrays in the JSON result.

Why does my text-only element return a string instead of an object?

If a tag contains only text (and optional attributes), it becomes a plain string for simplicity, unless attributes are present.

Can I upload an XML file instead of pasting?

Yes. The tool supports uploading .xml files and reads them locally using FileReader.

Can I format JSON output with custom indentation?

Yes. You can choose between 2 or 4 spaces in the Advanced Settings.
