关于「JSON格式化/压缩」

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。

  • <b>JSON 美化</b>：按指定缩进展开，方便阅读与排查结构。
  • <b>JSON 压缩</b>：移除全部空白字符，适合写入配置或减小传输体积。
  • <b>仅校验</b>：只检查语法并统计结构信息，不改变内容。
  • 语法出错时会给出<b>行号、列号与上下文片段</b>，便于快速定位。
  • 勾选<code>按键名排序</code>后可让两份 JSON 的键顺序一致，便于做差异比对。
  • 所有解析都在浏览器内存中完成，内容不会发送到任何服务器。

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「JSON格式化/压缩」
  1. 打开工具：打开「JSON格式化/压缩」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
美化和压缩有什么区别？
美化会加入换行和缩进，让层级结构一目了然，适合人阅读；压缩会去掉所有非必要空白，让体积最小，适合程序传输和存储。两者表达的数据完全相同。
为什么提示语法错误？
JSON 标准比 JavaScript 对象字面量严格：键名必须用双引号包裹，字符串不能用单引号，最后一个元素后不能有多余逗号，也不支持注释。请按提示的行列位置检查。
支持多大的文件？
受限于浏览器内存，通常几十 MB 以内都能正常处理。超大文件建议先拆分，否则页面可能出现短暂卡顿。
中文会被转义吗？
默认保持中文原样输出。如果你的系统需要纯 ASCII，可以勾选“中文转 \u 转义”，转义后的内容与原文等价。
数据安全吗？
整个过程是纯前端的：JSON 只存在于当前标签页的内存里，不上传、不缓存、不记录，关闭页面即销毁。
JSON Formatter/Minifier (English)

Beautify, minify, validate and highlight JSON.

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

  • <b>Beautify</b>: expands with the chosen indent for easy reading and structure inspection.
  • <b>Minify</b>: removes all whitespace, good for config files or smaller payloads.
  • <b>Validate only</b>: checks syntax and reports structure stats without changing content.
  • On syntax errors it reports the <b>line, column and a context snippet</b> for quick location.
  • Check <code>sort keys</code> to make key order consistent across two JSONs, easing diffs.
  • All parsing happens in browser memory; nothing is sent to any server.

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

Keywords: JSON Formatter/Minifier, JSON Tools, beautify, format, compress, online tool, free

How to use it

  1. Open the tool：Open the “JSON Formatter/Minifier” 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

What is the difference between beautify and minify?
Beautify adds newlines and indentation so the hierarchy is clear, good for humans; minify strips non-essential whitespace for the smallest size, good for transport and storage. The data is identical.
Why does it report a syntax error?
JSON is stricter than JS object literals: keys must be double-quoted, strings cannot use single quotes, no trailing commas, and no comments. Check the reported line/column.
How large a file is supported?
Limited by browser memory; usually up to tens of MB works fine. Split very large files first to avoid brief freezing.
Will Chinese be escaped?
Chinese is kept as-is by default. If your system needs pure ASCII, check “escape Chinese to \u”; the escaped content is equivalent to the original.
Is my data safe?
The whole process is client-side: JSON lives only in the current tab’s memory — no upload, cache, or log; it is destroyed when you close the page.
