🧬 XML to Go — Free Online Tool

Convert XML to Go online, free. XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. Go structs with field tags marshal cleanly to and from data formats. XML to Go 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 emits ready-to-use Go types as structs with json field tags following the The Go Programming Language Spec 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 Go microservices, CLIs and encoding/json struct mapping.

🚀 Why use this XML to Go tool?

It maps the full structure of your XML onto idiomatic Go types, following the The Go Programming Language Spec conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.

🧩Structure-aware mapping

Nested XML objects, tables and arrays are mapped faithfully onto Go, including nested types and optional fields.

🔒100% private

Your XML never leaves your device — everything is processed locally in JavaScript, with nothing logged or stored.

🆓Free, no signup

Unlimited conversions with no account, no quotas, and no watermark. Works on desktop and mobile.

What It Handles

Structure

  • Nested objects & tables
  • Arrays / lists
  • Deeply nested documents

Values

  • Inferred types (string, number, boolean)

  • Nested type names

Workflow

  • Copy or download output
  • Load an example to try it
  • Validate & format the input

Worked example

A XML document and its Go equivalent:

XML input:

<product>
  <sku>A-100</sku>
  <price>19.99</price>
  <active>true</active>
</product>

Output:

type Product struct {
    Sku string `xml:"sku"`
    Price float64 `xml:"price"`
    Active bool `xml:"active"`
}

Frequently Asked Questions

How do I convert XML to Go?

Paste your XML into the editor and press "Convert to Go". The tool parses it against the W3C XML 1.0 grammar, then generates Go types following The Go Programming Language Spec conventions — instantly and entirely in your browser. You can validate or format the XML first to be sure it is clean.

How is XML structure represented in Go?

XML has no native numbers, booleans or arrays. Repeated child elements become lists in Go, attributes and element text become fields, and values stay strings unless Go coerces them — so review numeric or boolean fields after converting.

Are optional fields detected when generating Go?

Optional or nullable members in the generated Go are inferred from keys missing in some records of your XML, following The Go Programming Language Spec. Include the optional fields in your sample so they are typed correctly.

What is the difference between XML and Go?

XML (eXtensible Markup Language) (XML) — XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. Go (Golang) structs (Go) — Go structs with field tags marshal cleanly to and from data formats. This converter maps the structure of your XML onto Go so you can use it for Go microservices.

Does the converter validate my XML first?

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 Go accurate.

Is my XML data private?

Yes. The entire XML-to-Go 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.

Where can I use the Go output?

The generated Go is ready for Go microservices, CLIs and encoding/json struct mapping. Copy or download it and drop it straight into your codebase.

🎓 Pro Tips

  • Tip 1: Validate or format your XML first (the Validate / Format buttons) so the converter works from clean, W3C XML 1.0-conformant input.
  • Tip 2: Give the tool a representative XML sample — optional fields are only detected from the keys actually present, so include them if they matter.
  • Tip 3: Authoritative reference for the input format: W3C XML 1.0 — https://www.w3.org/TR/xml/.
  • Tip 4: For the output, follow the The Go Programming Language Spec (https://go.dev/ref/spec) conventions in your codebase.

There are so many useful Use Cases for Converting XML to Go Structs

1. Interfacing with Web Services and APIs

Many web services and APIs return XML responses. Converting XML data into Go structs makes it easier to work with the data in your Go application.

type StockData {
Symbol   string `xml:"symbol"`
Price    float64 `xml:"price"`
Currency string  `xml:"currency"`
}

2. Data Integration and ETL Processes

XML files are often used for transferring data between systems. Go structs allow you to easily parse and transform this data before loading it into a database or another system.

type Employee {
ID       int    `xml:"id"`
Name     string `xml:"name"`
Role     string `xml:"role"`
}

3. Configuration Parsing

Many applications use XML for configuration files. Converting XML into Go structs allows you to read and manipulate configuration data directly.

type Config {
Database struct {
  Host     string `xml:"host"`
  Port     int    `xml:"port"`
  Username string `xml:"username"`
  Password string `xml:"password"`
} `xml:"database"`
}

4. Processing XML-based Data Feeds

Industries like e-commerce and media use XML for data feeds. Converting XML to Go structs allows you to easily process and update product information or other data.

type Product {
ID          string `xml:"id"`
Name        string `xml:"name"`
Description string `xml:"description"`
Price       float64 `xml:"price"`
}

5. Data Validation and Transformation

Once converted into Go structs, XML data can be easily validated, transformed, or used in business logic before being stored or transmitted.

type Order {
ID     string  `xml:"id"`
Amount float64 `xml:"amount"`
Date   string  `xml:"date"`
}

6. Data Migration

During data migrations, especially from legacy systems, converting XML data to Go structs makes it easier to map, transform, and load data into new systems.

type InventoryItem {
ProductID string `xml:"product_id"`
Quantity  int    `xml:"quantity"`
Location  string `xml:"location"`
}

7. Interacting with External Systems using XML Protocols

XML-based protocols like SOAP require parsing and processing XML messages. Go structs simplify this process when dealing with such protocols.

type SOAPResponse {
Status  string `xml:"status"`
Message string `xml:"message"`
}

8. Web Scraping and XML Data Extraction

Web scraping often involves extracting data from XML-based sources like RSS feeds. You can convert this XML data to Go structs to process and display it on your platform.

type RSSItem {
Title       string `xml:"title"`
Link        string `xml:"link"`
Description string `xml:"description"`
}
