Technical Details
We use js-yaml with optimized settings for readable output. The converter handles complex nested structures while maintaining proper YAML indentation (2 spaces) and avoiding unnecessary quoting.
FAQ
Will my YAML work with Kubernetes/Docker?
Yes! The output is fully compliant with YAML 1.2 specification and works directly with kubectl, docker-compose, ansible-playbook, and other DevOps tools without any modifications.
Why convert JSON to YAML?
Converting JSON to YAML is useful when you need to integrate data into a system that only accepts YAML format. JavaScript Object Notation - Lightweight data interchange format can be transformed into YAML (YAML Ain't Markup Language - Human-readable configuration format) for better compatibility.
Is my data secure during conversion?
Absolutely. Our converter works 100% client-side (in your browser). Your JSON data is never sent to an external server. Processing is instant and completely private.
What is the maximum JSON file size supported?
Since processing happens in your browser, the limit depends on available memory. Generally, files up to 10 MB are processed without issues. For larger files, we recommend splitting them.
How does JSON to YAML conversion work?
Our tool parses your JSON file, analyzes its data structure, then generates the equivalent in YAML format. Arrays, objects, and primitive values are intelligently mapped to YAML syntax.
Can I convert YAML to JSON?
Yes! We support bidirectional conversion. Use our YAML to JSON converter for the reverse operation.
