Online XML and YAML to JSON Converter: A Fast and Reliable Tool

Converting structured data is a routine yet critical task for developers, analysts, and content managers. Our online tool is designed to instantly convert XML, YAML, and YML formats to the universal JSON format. This is the ideal solution for preparing data for API transfer, integrating marketplace uploads into a database, or simply making configuration files readable.

Why do you need an XML/YAML to JSON converter?

Despite the popularity of JSON as a data exchange standard, XML and YAML remain widely used. XML is often used in corporate systems and banking APIs, while YAML (and its subset YML) is used in server configurations (Docker, Kubernetes) and product feeds for Yandex.Market or Google Merchant Center. Our converter solves this incompatibility problem by allowing you to transform these structures into JSON in just one click, without data loss or complex environment setup.

How to use the tool

We've simplified the process as much as possible by implementing an algorithm for automatic input data type detection. You don't need to specify the format manually— The system will automatically understand whether it's in XML or YAML.

Paste the source code (XML or YAML) into the left editor window or simply drag and drop the file.
The tool will instantly process the data and display the result in JSON format in the right window.
Use additional settings if necessary:
- Remove parameter prefix: Cleans JSON keys from technical characters (e.g. @ or _), which are added when converting XML attributes.
- Remove catalog type: A useful option for working with YML feeds— It removes the root element (e.g., yml_catalog), providing direct access to the content.
Click "Copy" to save the result to the clipboard.

Conversion Examples

1. XML to JSON (with Attributes)

Standard conversion converts XML attributes to keys with a prefix. Our tool allows you to make them "clean."

Copy
<product id="101" category="electronics">
<name>Smartphone</name>
<price>25000</price>
</product>

Result in JSON format:

copy
{
"product": {
"@id": "101",
"@category": "electronics",
"name": "Smartphone",
"price": "25000"
}
}

2. YAML in JSON

YAML is often used in DevOps and development. Quick conversion to JSON helps verify the validity of the data structure.

Copy
server:
host: 127.0.0.1
port: 8080
services:
- auth
- database

Result:

Copy
{
"server": {
"host": "127.0.0.1",
"port": 8080,
"services": ["auth", "database"]
}
}

Benefits and Applications Applications

This tool will be indispensable in the following scenarios:

YML feed processing: Convert supplier price lists to JSON for subsequent import to a website or CMS.
API debugging: If a third-party service returns responses in XML format, convert them to JSON for easier parsing and visual analysis.
System configuration: Quickly switch between YAML and JSON when configuring server-side software or front-end applications.
Security: All calculations occur in your browser (client-side). We do not store or transmit your data to the server.

Frequently Asked Questions (FAQ)

What should I do if @ symbols appear before field names in JSON?

This is standard behavior when converting XML; it denotes tag attributes. If they bother you, simply enable the Remove parameter prefix option in the tool settings.

Does the converter support large files?

Yes, the tool effectively handles large XML and YAML structures. However, it's important to remember that processing speed depends on your computer's resources, as parsing occurs inbrowser.

Is it possible to convert a Yandex.Market YML feed?

Absolutely. Our converter is specially optimized for working with YML. Use the Remove catalog type function to get an array of products without unnecessary nesting of the root element.

Why am I getting an error when inserting data?

The most likely cause is invalid source code syntax. Check for closing tags in the XML or correct indentation in the YAML. The tool will notify you if the data structure is corrupted.

What is the difference between YAML and YML?

Technically, there is nothing. .yml is the file extension, and YAML is the name of the format itself. The tool supports both formats equally well.

Use our XML and YAML to JSON converter to speed up development and automate routine tasks. It's a free, fast, and secure way to standardize your data without installing additional software.
