About XML to JSON conversion
XML is an extensible markup language released by W3C in 1998. It adopts a tag tree structure that separates attributes from text nodes, and is the base format for SOAP, RSS, SVG. It has strict syntax and high redundancy. JSON is a key-value and array interchange format defined in RFC 8259, with only six basic data types. The conversion requirement comes from format adaptation for different data interaction scenarios.
The output file size after conversion is smaller than the original XML file. The nested tree structure of XML corresponds to nested objects in JSON, XML tags are converted to JSON key names, and XML attributes can be retained as key-value pairs in objects. XML does not support native date types that are undefined in JSON, and XML has no standard structure corresponding to JSON comments, so comments are not retained after conversion.
This conversion is suitable for workflows such as data interaction in Web front-end development and mobile application interface data adaptation. The output is compatible with all JSON parsers that follow the RFC 8259 specification, and supports parsing and invocation by all mainstream browsers and operating systems.

FAQ about XML → JSON
Will data quality change after conversion
Well-formed XML can be fully mapped to the corresponding JSON structure, only XML comments are not retained. All valid tag content and nested levels can be output correctly, and the original data content will not be modified.
Can the original structure be fully retained
The nested tree structure of XML can be fully retained as nested objects in JSON, tag names are converted to JSON key names, and attributes can be retained as key-value pairs in objects. XML has no native standard for comments, so comments are not retained after conversion.
What is the maximum supported single file size
The single file size limit for this conversion service is 50MB, and only one file can be converted at a time. The service is free of charge, output has no watermarks, and no account registration is required.
Will files be stored
Conversion is completed on the server side, and files are uploaded via HTTPS. After conversion completes, the server immediately deletes both the source file and the output file, and does not store any files, to protect user data privacy.
