FAQ
What is JSON to YAML Converter?
Converts JSON objects and arrays to YAML 1.2 format with 2-space indentation. Input: JSON text (objects, arrays, nested structures). Output: YAML text with proper indentation. Use case: Kubernetes configs, CI/CD pipelines, configuration files.
How to convert JSON to YAML?
Paste JSON in the input textarea. Click 'Convert to YAML'. Result appears instantly with 2-space indentation. Copy with the 'Copy' button. Processing time: <1 second for files up to 1MB.
What JSON structures are supported?
Objects become YAML key-value pairs. Arrays become YAML lists with hyphens (-). Nested objects create indented blocks (2 spaces per level). Maximum nesting depth: unlimited. Strings with special characters are automatically quoted.
How are arrays handled?
Arrays become YAML lists with hyphens. Example: ["a","b","c"] becomes: - a, - b, - c. Nested arrays: each level adds 2-space indentation. Empty arrays: represented as []. Arrays with objects: each object becomes an indented block.
How are special characters handled?
Strings containing newlines, colons, hashes (#), or quotes are automatically wrapped in double quotes. Internal quotes escaped as \". Newlines preserved as literal newlines. Unicode supported: emojis, CJK characters, Arabic. Output encoding: UTF-8.
What is the output format?
YAML 1.2 compliant output. Indentation: 2 spaces (not tabs). No document markers (---) by default. Keys: unquoted when safe (no special chars). Values: quoted only when needed. Output is human-readable and valid YAML.
Can I convert YAML back to JSON?
No, this tool is one-way (JSON → YAML only). For YAML to JSON conversion, use the separate YAML to JSON tool. Note: comments in YAML are lost in JSON output.
What is the maximum file size?
Browser limit: ~50MB JSON input. Processing time: ~1 second per 1MB. For larger files (>100MB): split into chunks first. Memory usage: 2x input size during conversion. No server upload required.
Is my data safe?
Yes. All conversion runs locally in your browser using JavaScript. No data sent to servers. No cookies, no tracking, no registration. Works offline after initial page load.
Pro Tip
💡 Tip: For large files, consider compressing or splitting them first for faster processing. When batch processing, you can upload multiple files at once and the tool will process them automatically.
