Bidirectionally convert between JSON and YAML structured data formats, with support for custom output styling.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
JSON and YAML are text formats for representing structured values such as objects, lists, strings, numbers, booleans, and null. JSON uses braces, brackets, and commas; YAML commonly shows nesting through indentation and list markers. Converting between them parses the source into values and writes those values in the destination syntax. The output may have different spacing, line breaks, and quotes even when the represented data is equivalent.
For example, a JSON object with a service name and a list of ports can become a YAML mapping with an indented list. The converter handles JSON → YAML and YAML → JSON, and lets you choose two or four spaces for indentation. YAML 1.2 was designed for JSON compatibility, but individual parsers and YAML features can affect how a particular file is interpreted.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Start with JSON to YAML, or use the direction control to select YAML to JSON. The input should match the selected source format.
Enter a valid JSON value or YAML document. The output updates after a short pause. An empty input stays empty; a parse error clears the result and shows an error.
Choose two or four spaces. This changes how nested output is laid out, not the underlying values.
Check important keys and values, then copy or download the converted text. When reversing direction, the current result can become the new input.
Use cases
See how the tool fits into real work and everyday tasks.
When a project accepts YAML but a sample arrives as JSON, convert it to a more readable indentation-based view, then verify the exact key names and nesting before saving it.
For a code review or support discussion, convert a nested JSON example to YAML for easier scanning. Convert it back when a receiving system requires JSON.
If a field seems attached to the wrong parent, compare the braces or indentation in the two representations. The conversion can make structure easier to inspect, but it does not validate application-specific rules.
Q&A
Find concise answers to common questions and confusing cases.
The converter parses values and writes fresh text. Whitespace, quote style, and line breaks can change; compare the data and nesting rather than expecting a character-for-character copy.
No. JSON has no comment syntax, so YAML comments cannot be represented in JSON output. Review comments separately if they contain instructions or context you need.
No. YAML can express features with no direct JSON equivalent, and parser-specific tags or multiple documents may not be accepted as one JSON value. Test specialized files with the parser and application that will consume the output.
It should only change the output’s visual nesting. Still, YAML uses indentation as syntax, so check the generated structure before using it.
Notes
Review scope, result limitations, and important precautions before use.
YAML can include comments, anchors and aliases, explicit tags, and multiple documents. JSON has no direct representation for comments or every YAML-specific construct. Aliases may be expanded into repeated values, and unsupported or parser-specific constructs may fail or be interpreted differently. A successful conversion does not prove that the destination application accepts the result.
Conversion also does not validate a schema, required fields, deployment settings, or business rules. For production configuration, parse the output with the target software and review secrets and operational values before replacing a source file.
