关于「YAML转JSON」

它属于「JSON 工具」分类：JSON 的格式化、结构变换与各种数据格式互转。

  • 支持完整的 YAML 1.2 语法：嵌套映射、序列、多行字符串、锚点引用等。
  • 勾选<b>解析多文档</b>可处理用 <code>---</code> 分隔的多份文档，结果输出为数组。
  • 解析出错时会给出<b>具体行号</b>，方便定位缩进或语法问题。
  • YAML 里的日期、布尔值等会按标准规则转换成对应的 JSON 类型。
  • 请确保缩进只用空格，含制表符的 YAML 属于非法格式。

完全免费、无需注册；所有处理都在浏览器本地完成，文件不会上传到任何服务器。

如何使用「YAML转JSON」
  1. 打开工具：打开「YAML转JSON」页面，无需注册、无需安装任何软件。
  2. 准备输入：准备好要处理的内容或文件：文本可直接粘贴，文件可拖入页面（本工具属于「JSON 工具」）。
  3. 填入内容：把内容粘贴进输入框，或把文件拖入页面；也可以点击「示例」先填入样例数据试一下。
  4. 设置选项并处理：按需调整页面上的选项，然后点击处理 / 转换 / 生成按钮。
  5. 获取结果：处理完全在浏览器本地完成，结果可直接复制或下载，文件不会上传到任何服务器。
常见问题
提示解析失败，通常是什么原因？
最常见的是缩进不一致，或者误用了制表符。其次是冒号后面忘记空格（应写 <code>key: value</code>），以及含特殊字符的字符串没有加引号。
什么是多文档 YAML？
一个文件里可以用 <code>---</code> 分隔多份独立文档，Kubernetes 的资源清单经常这么写。勾选对应选项后，会把它们解析成一个 JSON 数组。
YAML 的注释会保留吗？
不会。JSON 格式本身不支持注释，转换后所有 <code>#</code> 注释都会被丢弃，这是格式差异导致的，无法避免。
YAML to JSON (English)

Parse YAML config into standard JSON.

Belongs to “JSON Tools”: Format, transform and convert JSON to and from various data formats.

  • Full YAML 1.2 syntax: nested maps, sequences, multiline strings, anchors and more.
  • Check <b>parse multi-doc</b> to handle several <code>---</code>-separated documents; output is an array.
  • On error it reports the <b>exact line</b>, helping locate indentation or syntax issues.
  • Dates, booleans, etc. in YAML convert to the matching JSON types by standard rules.
  • Use spaces for indentation only; YAML with tabs is invalid.

Free, no sign-up; everything runs locally in your browser and files are never uploaded.

How to use it

  1. Open the tool：Open the “YAML to JSON” page — no sign-up and nothing to install.
  2. Prepare the input：Prepare the content or file to process: paste text or drop a file onto the page (this tool belongs to “JSON Tools”).
  3. Provide the input：Paste your content into the input box or drop a file onto the page; you can also click “Sample” to try example data first.
  4. Adjust options and run：Adjust the options if needed, then click the process / convert / generate button.
  5. Get the result：Everything runs locally in your browser; copy or download the result — your files are never uploaded.

FAQ

Why does it say parse failed?
Most often inconsistent indentation or a stray tab. Next is missing space after a colon (write <code>key: value</code>), or unquoted strings with special chars.
What is multi-document YAML?
One file can hold several independent documents separated by <code>---</code>, common in Kubernetes manifests. With the option on, they parse into a JSON array.
Are YAML comments kept?
No. JSON has no comment syntax, so all <code>#</code> comments are dropped on conversion — an unavoidable format difference.
