YAML is a human-readable data serialization format that's often used for configuration files. It uses indentation to represent data hierarchy and is designed to be more readable than formats like JSON or XML.

How do I use this converter?

Simply paste your YAML content into the input field, adjust any formatting options if needed, and the converter will automatically transform it into JSON format. You can then copy or download the result.

What's the difference between YAML and JSON?

YAML is more human-readable and supports features like comments and multi-line strings. JSON is more strict and widely used for APIs. YAML is a superset of JSON, meaning all valid JSON is also valid YAML.

Can I convert any YAML to JSON?

Most YAML can be converted to JSON, but some YAML features (like comments and complex anchors) don't have JSON equivalents. Our converter handles these cases by either stripping unsupported features or providing appropriate warnings.

Does the converter preserve data types?

Yes, our converter maintains proper data types during conversion, including strings, numbers, booleans, arrays, and objects. It also handles null values and empty fields correctly.

Can I customize the JSON output format?

Yes, you can adjust indentation, choose between spaces and tabs, set array formatting, and control how special characters are escaped in the output JSON.

Is there a size limit for conversion?

The converter can handle files up to 10MB in size. For larger files, we recommend splitting them into smaller chunks or using our command-line tools.

How does error handling work?

The converter provides real-time syntax validation and detailed error messages, pointing out exact locations and reasons for any YAML parsing or conversion issues.

Where is YAML to JSON conversion commonly used?

This conversion is frequently used in DevOps workflows, configuration management, API development, and when migrating between different systems that use YAML or JSON.

Can I use this for Kubernetes configurations?

Yes! Our converter is particularly useful for working with Kubernetes manifests, allowing you to convert between YAML (commonly used for K8s configs) and JSON formats.

Is this suitable for API development?

Absolutely. Many developers use YAML for writing API specifications (like OpenAPI/Swagger) but need JSON for implementation. Our converter helps bridge this gap.

Can I automate the conversion process?

Yes, we offer an API endpoint for programmatic conversion, making it easy to integrate into your development workflow or automation scripts.

Why am I getting indentation errors?

YAML is sensitive to indentation. Make sure you're using consistent spacing (either spaces or tabs, not both) and that nested elements are properly aligned.

How do I handle multi-line strings?

YAML offers several ways to handle multi-line strings (using '>', '|', or folded style). Our converter properly handles all YAML multi-line string formats when converting to JSON.

What happens to YAML comments?

Since JSON doesn't support comments, they are stripped during conversion. If you need to preserve comments, consider using our 'preserve comments as fields' option.

Why does my numeric data convert to strings?

By default, the converter preserves numeric types. If you're seeing numbers converted to strings, check if they're properly formatted in the YAML or use our 'force number parsing' option.

Interesting History

Origins of YAML

YAML (YAML Ain't Markup Language) was first proposed by Clark Evans in 2001. Originally meaning "Yet Another Markup Language," it was renamed to emphasize that YAML is primarily for data, not documents.

JSON's Rise

JSON (JavaScript Object Notation) was created by Douglas Crockford in 2001. It emerged from JavaScript but quickly became a language-independent format, leading to the need for tools to convert between YAML and JSON.

Modern Usage

YAML gained popularity in configuration files for tools like Docker, Kubernetes, and GitHub Actions, while JSON became the de facto standard for APIs and web services, making YAML-JSON conversion essential.
