Which format should I use for configuration files?

YAML is the most human-readable for configuration — minimal punctuation, support for comments, and natural indentation. JSON is better when the config is consumed programmatically or shared across multiple languages. XML is typically a legacy requirement.

Does JSON to YAML preserve all data types?

Yes for the standard types: strings, numbers, booleans, null, arrays, and objects. YAML supports all of these natively. Very large integers may lose precision in JavaScript-based converters due to the float64 number type.

How does JSON to XML handle arrays?

Arrays are converted to repeated XML elements with the same tag name. For example, a JSON array named "items" with three entries becomes three child elements. The exact behavior may vary — check the output for your specific structure.

Transform Data Between JSON, YAML & XML

Modern software systems communicate using a variety of data serialization formats. REST APIs speak JSON, Kubernetes and CI/CD pipelines use YAML, older enterprise integrations expect XML, and data exports land in CSV. Manually converting between these formats is tedious and error-prone — a misplaced colon in YAML or a missing tag in XML can break an entire pipeline. devtoolkit.sh's format converters handle these transformations with one click. JSON to YAML converts a JSON structure to idiomatic YAML with correct indentation and scalar quoting, making it immediately usable in Helm charts, Ansible playbooks, and GitHub Actions workflows. JSON to XML wraps the structure in proper XML elements with configurable root tag names. JSON to CSV flattens a JSON array of objects into a spreadsheet-ready format. All converters run in your browser, so you can safely transform internal configuration data, database schemas, or API contracts without any privacy exposure.
