Data Format Converter

Professional data format conversion tool supporting bidirectional conversion between five common serialization formats: XML, JSON, TOML, CSV, and YAML. Helps developers quickly process different format configuration files and data exchange.

Supported Formats

XML

Extensible Markup Language, widely used in configuration files, data exchange, and document storage. High structuring degree, supports complex nested relationships.

JSON

JavaScript Object Notation, standard data format for Web APIs and modern applications. Lightweight and easy to parse, strong human-machine readability.

TOML

Concise and clear configuration file format with simple intuitive syntax. Commonly used in Rust, Python, and other project configuration management.

CSV

Comma-separated values format, universal standard for tabular data. Suitable for data import/export, Excel exchange, and other scenarios.

YAML

Human-friendly data serialization format using indentation to represent hierarchical relationships. Widely used in Docker, Kubernetes, and other tool configuration files.

How to Use

Tool uses intuitive dual-editor layout with source data on left and conversion results on right:

1. Select source format from left dropdown or use "Auto Detect" function
2. Select target format from right dropdown
3. Input or paste source data in left editor
4. Conversion results display in real-time in right editor

When selecting auto-detect, tool analyzes input content and displays detected format type on left.

Conversion Examples

JSON to YAML

{
  "server": {
    "host": "localhost",
    "port": 8080,
    "ssl": true
  }
}

Converts to:

server:
  host: localhost
  port: 8080
  ssl: true

CSV to JSON

name,age,city
Alice,30,Beijing
Bob,25,Shanghai

Converts to:

[
  {
    "name": "Alice",
    "age": "30",
    "city": "Beijing"
  },
  {
    "name": "Bob",
    "age": "25",
    "city": "Shanghai"
  }
]

Technical Features

• Smart Format Detection: Automatically recognizes XML, JSON, TOML, CSV, YAML formats
• Real-time Conversion: Instant conversion on input, no manual triggering needed
• Syntax Highlighting: Supports code highlighting for various formats
• Error Prompts: Provides clear error messages for format errors
• Local Processing: All conversions completed locally in browser, protecting data privacy

Notes

• Ensure source data format is correct, syntax errors will cause conversion failure
• Auto-detect function based on heuristic algorithms, recommend manually specifying format for complex situations
• CSV format suitable for flat tabular data, complex nested structures will be flattened
• XML and TOML require top-level to be object or array, single values automatically wrapped
• Different formats have varying expressive capabilities, some conversions may result in simplified structure
