About YAML ↔ JSON Converter
How the YAML ↔ JSON Converter Works
- Converts between YAML and JSON formats
- Validates the input to ensure it's properly formatted
- Formats with customizable indentation levels
- Preserves data structure during conversion
- Provides clear error messages for invalid input
Common Use Cases
- Converting configuration files between formats
- Transforming API responses to a more readable YAML format
- Converting YAML-based CI/CD configurations to JSON
- Migrating data between systems that use different formats
- Translating between human-readable YAML and machine-friendly JSON
Frequently Asked Questions
What is the difference between YAML and JSON?
YAML is a human-readable data serialization format that uses indentation and is easier to read and write. JSON is a lightweight data interchange format that uses brackets and braces and is widely supported by programming languages.
Can I convert any JSON to YAML?
Yes, any valid JSON can be converted to YAML format. The converter preserves all data types including strings, numbers, booleans, arrays, and objects during the conversion process.
Can I convert any YAML to JSON?
Most YAML can be converted to JSON, but some YAML features like comments, multi-line strings, and certain complex data types may not have direct JSON equivalents and could be lost in conversion.
How do I customize the indentation in the output?
Use the indentation selector at the bottom of the tool to choose between 1, 2, 3, 4, or 8 spaces. This affects both JSON and YAML output formatting.
What happens if my input has syntax errors?
The converter will display clear error messages indicating what's wrong with your input. Make sure your JSON or YAML is properly formatted before conversion.
Can I use this tool for configuration files?
Absolutely! This tool is perfect for converting configuration files between YAML and JSON formats, commonly used in CI/CD pipelines, Docker, Kubernetes, and various development tools.
How do I copy the converted output?
After conversion, click the "Copy to Clipboard" button that appears below the output area. The entire converted text will be copied for use in other applications.
Can I see examples of valid YAML and JSON?
Yes, click the "Sample" button in either section to load example data that demonstrates proper formatting and structure for both YAML and JSON.
Does the converter preserve data types?
Yes, the converter maintains data types including strings, numbers, booleans, arrays, and objects. However, some YAML-specific features like comments will not be preserved in JSON output.
Is there a size limit for the files I can convert?
While there's no strict limit, very large files may take longer to process and could affect browser performance. The tool works best with typical configuration files and data structures.
