YAML Formatter and Validator可以处理什么？
YAML Formatter and Validator 用于在浏览器中格式化和校验数据，并清楚显示处理结果和限制。 已核对的功能： YAML validation, YAML formatting, YAML to JSON, Expandable tree view.
Choose the view that matches the review task
Use formatted YAML for configuration editing, JSON for systems that require strict JSON, and Tree view to inspect deep values without scanning indentation.
如何使用？
- Paste one YAML document or load the included example.
- Choose formatted YAML, JSON, or Tree view.
- Run the parser and inspect, copy, or download the normalized result.

常见错误与修复方法
| 现象 | 可能原因 | 修复方法 |
|---|---|---|
| A bad indentation error appears. | Nested YAML levels are not aligned consistently. | Use spaces, align siblings, and avoid tab indentation. |
| Comments disappear after formatting. | The formatter normalizes parsed data rather than editing the original concrete syntax tree. | Keep a source-controlled original when comments and anchor style must be preserved. |
Important behavior of YAML Formatter
该工具的实际边界： Formatting through a data model does not preserve comments, anchors, aliases, or the exact original scalar style.

- YAML 1.2.2 specification (opens in a new tab)Defines YAML syntax and representation models.
- js-yaml documentation (opens in a new tab)Documents the local parser and dumper used by the tool.
关于YAML Formatter的常见问题
Does the YAML Formatter upload my input?
No. Processing runs in the current browser tab, and the page does not send tool input to a KitLumi processing endpoint.
What input does the YAML Formatter accept?
It accepts one YAML document. The workspace checks the input and reports malformed or unsupported values before it produces a result.
What does the YAML Formatter produce?
It produces formatted YAML, two-space JSON, or a structured tree. Copy and download controls appear when the output format supports them.
What limitation should I know?
Formatting through a data model does not preserve comments, anchors, aliases, or the exact original scalar style.
