About This Tool
What is Data Format Converter?
A tool for converting and validating between JSON, YAML, TOML, XML, INI, and Properties data formats. Useful for configuration file migration, data format verification, and cross-format compatibility checks.
How to Use
- Select the input format and the desired output format.
- Paste your data into the input area.
- Use 'Format' to prettify or 'Minify' to remove whitespace.
- Change the output format to convert to a different format.
Key Features
- Supports 6 formats: JSON, YAML, TOML, XML, INI, Properties
- Automatic validation during format conversion
- Format (prettify) and Minify functions
- Format compatibility matrix provided
Tips
- JSON is the most universal data format supported by virtually all programming languages.
- YAML is human-readable due to indentation but prone to errors in complex structures.
- Converting from INI/Properties to JSON flattens nested structures using dot notation.

Frequently Asked Questions
Which data format should I use for configuration files?▼
YAML is popular for human-edited config files (e.g., Docker Compose, Kubernetes) due to its readability. TOML is great for simpler configs (e.g., Cargo.toml, pyproject.toml). JSON is ideal for machine-generated configs and API communication. Choose based on your ecosystem and readability needs.
Why does my YAML-to-JSON conversion produce unexpected results?▼
YAML has implicit type coercion — values like 'yes', 'no', 'on', 'off' are interpreted as booleans, and unquoted numbers may lose leading zeros. Always quote ambiguous string values in YAML to prevent unintended type conversion.
Can I convert XML with attributes to JSON without losing data?▼
XML attributes don't have a direct equivalent in JSON. During conversion, attributes are typically prefixed with '@' or placed in a special property. Complex XML with mixed content (text + elements) may not convert perfectly to flat JSON structures.
