Convert XML to JSON Schema online, free. XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. JSON Schema is a vocabulary for validating and documenting the shape of JSON data. XML to JSON Schema conversion parses your XML against the W3C XML 1.0 grammar (https://www.w3.org/TR/xml/), builds an in-memory model of its keys, nested objects and arrays, then derives a JSON Schema that describes that shape following the JSON Schema 2020-12 conventions. Processing runs in your browser in JavaScript with no upload or server round-trip — no size limit beyond your device's memory, so multi-megabyte documents convert in milliseconds and sensitive payloads never leave your machine. Typical uses include API request/response validation, form generation and contract testing.
It maps the full structure of your XML onto a valid JSON Schema, following the JSON Schema 2020-12 conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Paste XML and derive a JSON Schema from JSON Schema immediately. Conversion runs client-side, so there is no upload wait and large documents stay fast.
Nested XML objects, tables and arrays are mapped faithfully onto JSON Schema.
Your XML never leaves your device — everything is processed locally in JavaScript, with nothing logged or stored.
Unlimited conversions with no account, no quotas, and no watermark. Works on desktop and mobile.
A XML document and its JSON Schema equivalent:
XML input:
<product>
<sku>A-100</sku>
<price>19.99</price>
<active>true</active>
</product>Output:
{
"type": "object",
"properties": {
"sku": { "type": "string" },
"price": { "type": "number" },
"active": { "type": "boolean" }
},
"required": ["sku", "price", "active"]
}Paste your XML into the editor and press "Convert to JSON Schema". The tool parses it against the W3C XML 1.0 grammar, then derives a JSON Schema following JSON Schema 2020-12 conventions — instantly and entirely in your browser. You can validate or format the XML first to be sure it is clean.
XML has no native numbers, booleans or arrays. Repeated child elements become lists in JSON Schema, attributes and element text become fields, and values stay strings unless JSON Schema coerces them — so review numeric or boolean fields after converting.
The derived JSON Schema records the required keys and the value type of each field seen in your XML sample. Widen it by hand if some fields are optional or can hold more than one type.
XML (eXtensible Markup Language) (XML) — XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. a JSON Schema (JSON Schema) — JSON Schema is a vocabulary for validating and documenting the shape of JSON data. This converter maps the structure of your XML onto JSON Schema so you can use it for API request/response validation.
Yes. Invalid XML is flagged with a clear error before anything is converted. Common XML problems to check are matched start and end tags, a single root element, and quoted attribute values. Starting from clean input keeps the generated JSON Schema accurate.
Yes. The entire XML-to-JSON Schema conversion runs locally in your browser in JavaScript — your XML is never uploaded, logged or stored. That matters when the data is something like SOAP web services, which should not leave your machine.
The generated JSON Schema is ready for API request/response validation, form generation and contract testing. Copy or download it and drop it straight into your validation or codegen pipeline.
Many APIs use XML, but JSON is more widely supported. Converting XML to JSON Schema makes integration easier.
{
"type": "object",
"properties": {
"symbol": { "type": "string" },
"price": { "type": "number" },
"currency": { "type": "string" }
}
}JSON Schema makes it easy to map data across systems. Converting XML to JSON Schema simplifies data integration.
{
"type": "object",
"properties": {
"id": { "type": "integer" },
"name": { "type": "string" },
"role": { "type": "string" }
}
}JSON Schema is more efficient for reading and manipulating configuration data.
{
"type": "object",
"properties": {
"database": {
"type": "object",
"properties": {
"host": { "type": "string" },
"port": { "type": "integer" },
"username": { "type": "string" },
"password": { "type": "string" }
}
}
}
}Many industries use XML for data feeds. Converting it to JSON Schema simplifies processing and updating data.
{
"type": "object",
"properties": {
"id": { "type": "string" },
"name": { "type": "string" },
"description": { "type": "string" },
"price": { "type": "number" }
}
}JSON Schema allows for easy validation of incoming data.
{
"type": "object",
"properties": {
"id": { "type": "string" },
"amount": { "type": "number" },
"date": { "type": "string" }
}
}Migrating data between systems is easier when converting XML to JSON Schema.
{
"type": "object",
"properties": {
"product_id": { "type": "string" },
"quantity": { "type": "integer" },
"location": { "type": "string" }
}
}JSON is the preferred format for external systems. JSON Schema simplifies working with external protocols.
{
"type": "object",
"properties": {
"status": { "type": "string" },
"message": { "type": "string" }
}
}Web scraping data often involves XML. Converting it to JSON Schema helps you handle it more easily.
{
"type": "object",
"properties": {
"title": { "type": "string" },
"link": { "type": "string" },
"description": { "type": "string" }
}
