📖 Description
1. Core Application Scenarios
- API Adaptation: Convert data returned by backend SOAP/XML interfaces into JSON for direct use in frontend frameworks like React/Vue.
- Configuration Migration: Quickly refactor legacy XML configuration files (e.g., Java
.xml configurations) into modern JSON format, or perform the reverse operation.
- Multi-System Integration: Act as an intermediary bridge between heterogeneous systems supporting different data formats to align data structures.
- Learning & Research: Visually compare how the same set of data is expressed in XML nested tags versus JSON key-value pairs to deepen understanding of data structures.
2. Core Feature Analysis
This site employs a high-performance parsing engine that addresses the pain points of structural differences between the two formats:
A. Intelligent Structure Mapping
- Attribute Extraction: Automatically handles XML node Attributes and Content, intelligently mapping them to JSON object key-value pairs.
- Array Handling: Identifies repeated XML tags with the same name and accurately converts them into JSON Arrays, preventing data loss.
B. Real-time Bi-directional Conversion
- XML to JSON: Supports conversion of complex XML with namespaces and CDATA blocks.
- JSON to XML: Automatically generates a root node and recursively creates corresponding XML tag hierarchies based on the nesting depth of the JSON.
C. Syntax Checking & Formatting
- Performs real-time syntax validation during conversion. If the source data has unclosed tags (XML) or missing commas (JSON), the tool will highlight the errors immediately.
- Conversion results are automatically beautified with indentation, requiring no secondary formatting.
D. 100% Local Processing (Zero-Upload Privacy)
- The conversion algorithm runs entirely in the browser. Your commercial order data, system configuration information, or private interface parameters are never uploaded to a server, ensuring data security from the source.
3. Brief Operation Process
- Input Data: Paste the source code into the left input box (supports dragging and dropping files).
- Select Mode: * Click "XML → JSON" to parse.
- Click "JSON → XML" to encapsulate.
- Configuration Options (Optional): * Choose whether to preserve XML attributes.
- Set the number of indentation spaces (2 or 4).
- Result Export: The conversion result is displayed instantly on the right. Click "Copy Result" or "Download File".

| Data Characteristic |
XML Representation |
JSON Representation |
| Hierarchical Relation |
Nested tags <parent><child/></parent> |
Nested object {"parent": {"child": {}}} |
| Repeated Elements |

Array ["A", "B"] |
| Attribute Values |
<user id="101">John</user> |
Object {"user": {"@id": "101", "#text": "John"}} |
| Comments |

(Typically ignored during conversion; JSON does not natively support comments) |
5. Why Choose This Online Conversion Tool?
- Minimalist Experience: Split-pane layout provides clear visibility of conversion results, avoiding complex operational hierarchies.
