XML to TOML Converter

About XML to TOML Converter

Convert XML data to TOML (Tom's Obvious, Minimal Language) format, a popular configuration file format used by Rust, Hugo, and many other modern applications.

Key Features

• Automatic Type Detection: Recognizes strings, integers, floats, booleans, and dates
• Array of Tables: Supports [[table]] syntax for repeated items
• Key Sanitization: Converts XML tags to valid TOML keys
• Proper Escaping: Handles special characters in strings
• File Upload: Upload .xml files directly
• Copy & Download: Easy export as .toml file

How to Use

1. Input XML Data: Paste your XML data or upload an .xml file
2. Configure Options: Choose table array format
3. Review Output: The TOML configuration generates automatically
4. Copy or Download: Use the Copy or Download button to save your TOML file

TOML Syntax

• [[table]]: Array of tables for repeated items
• [table.section]: Named sections for grouped data
• key = value: Key-value pairs with type inference
• Strings: Quoted with proper escaping
• Numbers: Integers and floats without quotes
• Booleans: true or false (lowercase)

Example Conversion

XML Input:

<?xml version="1.0" encoding="UTF-8"?>
<servers>
  <server>
    <name>alpha</name>
    <ip>10.0.0.1</ip>
    <port>8080</port>
    <enabled>true</enabled>
  </server>
  <server>
    <name>beta</name>
    <ip>10.0.0.2</ip>
    <port>8081</port>
    <enabled>false</enabled>
  </server>
</servers>

TOML Output (Array of Tables):

[[servers]]
name = "alpha"
ip = "10.0.0.1"
port = 8080
enabled = true

[[servers]]
name = "beta"
ip = "10.0.0.2"
port = 8081
enabled = false

Common Use Cases

• Rust Projects: Cargo.toml configuration files
• Hugo: Static site generator configuration
• Application Config: Modern application configuration files
• Package Management: Poetry, pipenv, and other tools
• Infrastructure: Docker Compose, Kubernetes configs

Type Detection

The converter automatically detects and formats data types:

• Strings: Quoted text with escaped special characters
• Integers: Whole numbers without quotes (e.g., 42)
• Floats: Decimal numbers without quotes (e.g., 3.14)
• Booleans: true or false (case-insensitive input)
• Dates: ISO 8601 format (e.g., 2024-01-15)

TOML Benefits

• Human-Readable: Easy to read and write
• Unambiguous: Clear syntax with minimal edge cases
• Type-Safe: Strong typing for configuration values
• Modern: Widely adopted in modern tooling
• Minimal: Simple syntax without unnecessary complexity

Privacy & Security

All conversions happen locally in your browser. Your XML data is never uploaded to any server, ensuring complete privacy and security.

FAQs

• What XML layout is expected? A single root element (for example, <servers>) with repeated children (such as multiple <server> nodes) and consistent child tags creates the best TOML tables.
• When should I use [[table]] vs [table.item]? Use [[table]] when you have many similar items (like servers or users). Use [table.item] when you prefer named sections (such as [servers.alpha], [servers.beta]).
• How are types inferred? The tool detects booleans, integers, floats, ISO dates, and falls back to strings with proper escaping when needed.
• Is the output ready for tools like Cargo or Hugo? Yes. The TOML syntax is standards-compliant; you may just need to adjust table names to match your project’s conventions.
• Does any configuration data leave my browser? No. All parsing and TOML generation are performed locally.
