JSON vs XML vs YAML: Which Formatter Should You Use?

Compare three common structured-data formats and choose the right ToolCraft formatter for your file or workflow.

JSON, XML and YAML all represent structured information, but they have different syntax and common use cases. Choosing the correct formatter starts with identifying the format of the data you already have.

JSON

JSON is common in APIs and JavaScript applications. Use the JSON Formatter & Validator for readable JSON and syntax checks.

XML

XML remains common in feeds, integrations and configuration formats. The XML Formatter & Validator helps inspect XML structure.

YAML

YAML is widely used for human-readable configuration. The YAML Formatter & Validator helps you inspect and validate YAML content.
