About YAML to JSON Converter – Convert YAML to JSON Online
Convert YAML files, Kubernetes manifests, and CI/CD configurations into formatted, valid JSON.
Inspect syntax errors with exact line and column locations, and format output with 2-space or 4-space indentation.
Input is processed locally in your browser and is not sent to Navorika.
How the calculation works
YAML Document Parsing
The YAML parser scans tokens, validates indentation levels, resolves aliases and anchors, and builds an abstract syntax tree.
JSON Normalization
The parsed object graph is formatted into standard JSON with deterministic string escaping and customizable indentation.
How to use this tool
- 1Paste or upload your .yaml or .yml configuration file.
- 2Select your preferred indentation format (2 spaces or 4 spaces).
- 3Review syntax warnings or error lines highlighted in the editor.
- 4Copy the converted JSON result or download the formatted .json file.
Understanding the result
YAML key-value mappings become JSON objects; YAML sequence lists become JSON arrays.
YAML aliases and anchors (*anchor) are resolved to their referenced values in JSON.
Important limitations
- YAML custom type tags (!custom) and binary blobs must be represented as standard JSON primitives or objects.
- Multi-document YAML streams (separated by ---) convert the primary or first document.
