Tool Introduction
This tool is an efficient and convenient online XML/YAML converter, designed to help users achieve bidirectional conversion between XML and YAML data formats. Whether you need to convert complex XML structures into concise YAML for configuration, or transform clear YAML data into standard XML format for transmission, this tool can handle it with ease. It provides rich customization options, including XML indentation, compact mode, ignoring XML attributes, ignoring comments, ignoring XML declaration headers, and YAML indentation, ensuring that the conversion results meet your specific needs.
How to Use
- **Input Data:** Paste your XML data into the "XML Code" input box, or paste your YAML data into the "YAML Code" input box.
- **Adjust Conversion Options:** Adjust the parameters on the right according to your conversion needs:
- **XML Indent:** Set the number of spaces for XML output indentation, default is 4.
- **XML Compact Mode:** When checked, XML output will be more compact, reducing unnecessary whitespace.
- **Ignore XML Attributes:** When checked, XML element attributes will be ignored during conversion.
- **Ignore Comments:** When checked, comment content in XML will be ignored during conversion.
- **Ignore XML Declaration Header (<?xml ...?>):** When checked, the output XML will not contain the declaration header.
- **YAML Indent:** Set the number of spaces for YAML output indentation, range 2-8, step 2, default is 2.
- **View Results:** The tool will convert in real-time based on input and options, and the results will be immediately displayed in the other code box.
- **Copy and Use:** You can directly copy the converted code from the output box.
Usage Examples

Frequently Asked Questions
- Q: What input formats are supported? A: This tool supports XML and YAML input formats. You can convert XML to YAML, or YAML to XML.
- Q: What is the output format? A: Depending on your conversion direction, the output will be a well-formatted XML string or YAML string.
- Q: What custom options are supported during conversion? A: This tool provides rich custom options, including XML indentation, XML compact mode, ignoring XML attributes, ignoring XML comments, ignoring XML declaration headers, and YAML indentation.
- Q: Is this tool bidirectional? A: Yes, this tool supports bidirectional conversion from XML to YAML and YAML to XML, meeting data format interconversion needs in different scenarios.
Notes
- When entering XML or YAML data, please ensure that its format is correct. Incorrect format may lead to conversion failure or abnormal output.
- The setting of conversion options will directly affect the structure and content of the final output. Please carefully adjust each parameter according to your specific needs.
- For XML containing namespaces, CDATA sections, or complex mixed content, some semantics may be lost or manual adjustments may be required after converting to YAML.
- Before performing large-scale data conversion, it is recommended to test with a small amount of data to verify that the conversion result meets expectations.
Introduction to XML and YAML
XML (Extensible Markup Language) is a markup language designed for transmitting and storing data. It represents structured data in a human-readable way and is widely used in web services, configuration files, and data exchange. XML defines the structure and type of data elements through tags, possessing good scalability and expressiveness, but its syntax is relatively verbose.
YAML (YAML Ain't Markup Language) is a human-friendly data serialization standard, often used for configuration files and data transmission. YAML's design goal is readability; it uses indentation and concise syntax to represent data structures, making it more compact and intuitive than XML. It supports various data types such as lists and dictionaries (mappings) and is widely adopted by many modern programming languages and development frameworks.
XML and YAML Conversion Scenarios
XML and YAML, as two popular data representation formats, each have their advantages in practical applications. The need for conversion between them mainly arises in the following scenarios:
- **Data Format Unification:** When processing data from different systems or services, it may be necessary to convert XML data to YAML, or vice versa, for unified processing and analysis.
- **Configuration File Management:** Many modern applications prefer to use YAML as the configuration file format because it is more concise and readable. However, some traditional systems or specific services may still rely on XML configuration.
- **API Interaction:** Different APIs may require or return data in different formats. For example, an API might accept XML requests but return YAML responses.
- **Data Migration and Compatibility:** During system upgrades, data migration, or compatibility with other systems, conversion between XML and YAML is a key link to ensure data continuity and usability.
- **Development and Debugging:** During development and debugging, converting complex XML structures into a more understandable YAML format helps quickly identify problems and understand data flow.
