Many legacy systems use XML for configuration, while modern development favors the simplicity of TOML. Our XML to TOML converter bridges this gap, allowing you to modernize your workflows without manual retyping.
What is XML/TOML Conversion?
This conversion process takes the verbose, tag-based structure of XML and maps it to the key-value based syntax of TOML. It effectively flattens the hierarchy and converts attributes and child nodes into tables and keys.
Why Use Our XML to TOML Converter?
- Intelligent mapping of XML attributes to keys (using @ prefix)
- Automatic handling of repeating tags as TOML arrays of tables
- Real-time conversion with high performance
- Safe and private: no server-side data processing
- Support for complex XML namespaces and schemas
- Easy to use with no technical setup required
How to Convert XML to TOML
Paste XML
Paste your XML code or upload an .xml file.
Validate Structure
The tool ensures your XML is well-formed before conversion.
Review TOML
See your XML tags transformed into TOML sections and keys.
Export Result
Copy the code or download the final .toml file.
Key Features
Attribute Support
Attributes are preserved using the @name convention in TOML.
Repeating Element Detection
Automatically identifies identical sibling tags and converts them to arrays.
Prettified Output
Generates clean, indented TOML that is ready for production use.
Error Highlighting
Pinpoints syntax errors in both XML and TOML formats.
Best Practices
- Ensure your XML has a clear root element
- Check for consistent child node names for better array generation
- Remove unnecessary namespaces if they clutter your configuration
- Review attribute mapping to ensure keys meet your naming standards
Common Use Cases
Modernizing Configs
Upgrading XML-based legacy software configurations to TOML.
Data Interchange
Converting XML exports from old databases to TOML for modern app development.
Schema Mapping
Quickly testing how complex XML schemas translate to key-value maps.
Frequently Asked Questions
What happens to XML attributes?
They are prefixed with @ and placed inside the corresponding TOML table.
Are namespaces supported?
Yes, although they may be simplified depending on the target TOML structure.
Is there a limit on XML nesting?
No, the tool handles deep hierarchies by creating nested TOML tables.
Can I convert TOML back to XML?
Yes, this tool is bidirectional.
