FAQ
Q: Is my data secure?
Yes! All conversion happens entirely in your browser. Your data never leaves your device.
Q: Why convert JSON to YAML?
YAML is more human-readable and supports comments, making it ideal for configuration files. Many tools like Docker Compose and Kubernetes prefer YAML for configuration.
Q: Can I convert large JSON files?
Yes, the tool can handle JSON files up to several megabytes. For optimal performance, we recommend files under 5MB.
Q: Will comments be preserved?
JSON doesn't support comments, so the output YAML won't contain any comments. However, you can add comments to the YAML output after conversion.
