A two-way conversion tool for JSON and XML data structures, designed for development, testing, and data processing.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
This converter works in both directions: JSON to XML or XML to JSON. Use the direction control to choose the input and output formats, paste the source, and select the indentation style for formatted output. JSON represents values such as objects and arrays; XML represents nested elements, attributes, and text. Because those structures do not line up in one universal way, conversion applies a mapping rather than preserving every source detail.
In JSON-to-XML conversion, the mapping recognizes reserved keys for attributes and element text; ordinary object keys become element names, while arrays are represented through repeated elements. XML-to-JSON conversion maps XML elements into a JSON structure. Namespaces, mixed text and child elements, comments, processing instructions, and other XML-specific details may not round-trip as originally written. RFC 8259 and the W3C XML specification define the respective formats, but neither dictates a single universal JSON/XML mapping.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Choose JSON to XML or switch the direction for XML to JSON. The input example and output area follow the selected direction.
Paste a JSON value or XML document into the input pane. If conversion fails, check the source syntax, matching delimiters, quoted strings, and closing XML tags.
For JSON-to-XML output, select two spaces, four spaces, or tabs. Indentation changes whitespace for readability; it does not change the data mapping.
Compare the output structure with the source before copying it into an application. Pay special attention to arrays, attributes, and text content if the destination expects a particular schema.
For example, a JSON object with a name field can map to an XML element named name. That is a structural translation; it does not preserve the original JSON punctuation or formatting.
Use cases
See how the tool fits into real work and everyday tasks.
Preview how a small JSON object is represented as XML before deciding whether it fits a receiving system’s expected element structure.
Turn a simple XML document into JSON-shaped output for a workflow that consumes objects and arrays.
Share a readable, indented example with a teammate while checking that the chosen mapping preserves the fields your use case needs.
Q&A
Find concise answers to common questions and confusing cases.
Not for every input. JSON and XML have different data models, and conversion requires choices about arrays, text, attributes, and element names. Check the output against the structure required by your application.
They change the whitespace used to format JSON-to-XML output. They do not change the represented values or make a mapping more complete.
XML can include namespaces, mixed content, comments, and other constructs that do not have a direct counterpart in ordinary JSON. The converter’s mapping may omit or reshape those details.
Notes
Review scope, result limitations, and important precautions before use.
A successful conversion only shows that the input could be mapped into output. It does not certify that the result meets a schema, API contract, or application-specific requirements.
