Best Practices
YAML to JSON Conversion
- Use consistent indentation (2 or 4 spaces) for readability
- Validate YAML syntax before conversion to catch errors early
- Consider data types - YAML comments and anchors are lost in JSON
- Test the converted JSON with your target system or API
JSON to YAML Conversion
- Choose appropriate indentation (2 spaces is standard for YAML)
- Use key sorting for consistent output across conversions
- Validate the generated YAML for syntax and structure
- Consider adding comments to the YAML for better documentation
Frequently Asked Questions
What's the difference between YAML and JSON?
YAML is a human-readable data serialization format that supports comments, anchors, and complex data types. JSON is a lightweight data interchange format that's more compact but doesn't support comments or references.
Can I convert files larger than 100MB?
The tool supports files up to 100MB. For larger files, consider splitting them into smaller chunks or using command-line tools for batch processing.
Are YAML comments preserved when converting to JSON?
No, YAML comments are not preserved when converting to JSON as JSON doesn't support comments. The conversion focuses on the data structure and values.
Is my data secure during conversion?
Yes, all conversion happens locally in your browser. No data is sent to external servers, ensuring complete privacy and security of your configuration files.
