Java to XML Converter
Paste Java classes or POJOs. Get clean XML back.
What this tool does
If you have ever had to hand-build an XML payload that matches a Java class — for a SOAP client, a Spring config, a legacy banking integration, or a JUnit fixture — you already know how tedious that is. Paste the Java here and you get back well-formed XML in one shot. A single POJO, a file with Lombok-annotated DTOs, or a deeply nested model with several classes — same result: a complete XML document with every field preserved.
It is not blind templating. The converter knows how Java serializes to XML: BigDecimal keeps its exact precision (no scientific notation), LocalDate and LocalDateTime come out as ISO-8601, UUID becomes a standard 8-4-4-4-12 hex string, Instant is a Z-suffixed timestamp, and boxed primitives with null values become empty elements. List<T> becomes a container element — by default wrapped, with one child per item — matching what Jakarta XML Binding (JAXB) would produce.
Annotations are honoured exactly the way Eclipse JAXB RI treats them. @XmlRootElement(name="...") renames the root, @XmlElement(name="...") renames a child, @XmlAttribute emits the field as an attribute on the parent, @XmlTransient drops it entirely, and @XmlElementWrapper adds the outer container around a collection. Lombok @Data works too — the generated getters and setters are treated as bean properties. If you prefer the Jackson XML module, its @JacksonXmlProperty and @JacksonXmlElementWrapper are honoured as well. Nested classes, inherited fields, and multiple top-level classes all come through cleanly.
How to use it
Three steps. Works the same whether you paste a single POJO or a file with a dozen classes.
Paste your Java (or try the sample)
Drop your Java into the left editor as-is. A plain POJO, a @Data Lombok class, a JAXB-annotated DTO, or a file with multiple classes — all work. Click Load Sample to see a realistic example first.
You do not need to strip imports, remove annotations, or clean up the file. Paste it the way it sits in your IDE — comments, package statement, and all.
Hit Convert
Click the green Convert button. The tool reads the Java, preserves every field and class, honours the annotations, and builds the XML in one pass. You will see a brief loading indicator while it runs.
Copy the XML
The right panel fills with indented, well-formed XML that a standards-compliant XML parser will accept. Copy it into your SOAP envelope, Spring Boot config, integration test, or XSD-backed schema example.
When this actually comes in handy
Building SOAP fixtures
You have a JAX-WS or Apache CXF request DTO and need an XML body for SoapUI or Postman. Paste the class, get the envelope-ready XML, move on with your day.
Spring Boot XML configs
A Spring @ConfigurationProperties class with 30 fields turns into a ready-to-edit XML template — no handwriting the applicationContext.xml boilerplate.
Keeping docs and code aligned
Generate XML examples for a README, an internal wiki, or XSD-backed schema docs straight from your actual entity classes, so the examples never drift from the code.
Seeding legacy integration tests
Turn your JUnit object-mothers into XML seed files for mock servers, IBM MQ fixtures, or legacy enterprise systems that still speak XML.
Common questions
Can I paste multiple classes at once?
Yes — paste a whole file. Each top-level class comes through with nested types expanded and inherited fields from superclasses rolled in. Classes the root does not reference are emitted as separate XML fragments so nothing is silently dropped.
Does it respect JAXB annotations like @XmlRootElement, @XmlElement, @XmlAttribute, and @XmlTransient?
Yes. @XmlRootElement(name="x") renames the root, @XmlElement(name="x") renames a child, @XmlAttribute(name="x") emits the field as an attribute on the parent, @XmlTransient drops it, and @XmlElementWrapper adds the outer container around a collection. This matches the behaviour spelled out in the JAXB tutorial.
What about Lombok and Jackson XML?
Lombok @Data, @Getter, and @Setter are treated as if the accessors were written by hand. Jackson XML annotations — @JacksonXmlProperty, @JacksonXmlRootElement, @JacksonXmlElementWrapper, @JacksonXmlText — are honoured too, so classes built for the Jackson dataformats-text XmlMapper come through correctly.
How does it handle BigDecimal, LocalDate, UUID, and null fields?
BigDecimal keeps full precision, no scientific notation. LocalDate, LocalDateTime, and ZonedDateTime come out as ISO-8601 strings. Instant gets a Z suffix. UUID is the standard 8-4-4-4-12 lowercase hex. Optional.empty() and boxed primitives with null become empty elements rather than being dropped, so the shape of the XML stays consistent across instances.
Is my code stored?
Your code is sent to the backend for conversion and is not persisted — we do not log the payload. Same caveat as any online tool: if the code is genuinely sensitive, look it over before pasting.
What if the class has something unusual — Streams, CompletableFuture, or a transient field?
Fields marked transient or annotated @XmlTransient / @JsonIgnore are skipped. Types the XML world does not have a direct mapping for (Streams, CompletableFuture, custom functional interfaces) come out as empty elements rather than failing the whole conversion. If the Java itself has a compile error, fix the obvious ones first — the parser is forgiving but not a full javac.
