When to Convert

Common scenarios where this conversion is useful

Integrating with Java and .NET systems

Enterprise Java and .NET applications commonly use XML configuration. Convert TOML settings to XML for compatibility with Spring, Hibernate, or ASP.NET.

Generating SOAP request payloads

SOAP web services require XML-formatted requests. Convert TOML-structured data into XML payloads for SOAP API testing and integration.

Creating Maven or Ant build configs

Convert project settings stored in TOML into XML format suitable for Maven pom.xml or Ant build.xml files.

Data export for XML-based workflows

Convert TOML data files to XML for import into systems that accept XML input, such as content management systems or document processing tools.

Frequently Asked Questions

Each [table] section becomes an XML parent element. Keys within the table become child elements. For example, [server] with port = 8080 becomes <server><port>8080</port></server>.

TOML arrays become repeated XML elements with the same tag name. Array of tables [[items]] become repeated <items> elements each containing their key-value child elements.

XML treats all content as text by default. TOML integers, floats, booleans, and dates are converted to their string representation in XML element text.

Yes. The output starts with <?xml version="1.0" encoding="UTF-8"?> followed by a root element containing your converted TOML data.

A <root> element wraps the entire output. Top-level TOML keys become direct children of this root element.

No. TOML comments are not carried into the XML output. You can add XML comments manually after conversion if needed.

Dotted keys like database.host are expanded into nested XML elements: <database><host>value</host></database>.

Yes. Inline tables are expanded into standard XML element nesting, the same as regular TOML tables.

TOML multi-line strings are output as XML text content with the line breaks preserved in the element body.

Yes. The conversion runs entirely in your browser. Your TOML files, which may contain sensitive settings, are never sent to any server.
