简言之： JSON 是网络的数据交换格式。格式化工具让杂乱的负载可读、发现语法错误，并为 API、配置和日志准备数据。
1) 什么是 JSON
JSON（JavaScript Object Notation）是用于存储和传输结构化数据的文本格式。API、配置、日志和 webhook 每天都在使用它。
2) 为什么需要 JSON 格式化工具
- Readability. API responses often arrive as one long line.
- Error finding. A trailing comma or missing brace breaks parsing.
- Debugging. Easier to inspect fields before sending a request.
- Sharing. Pretty JSON is easier to paste into docs and chats.
- Minifying. Sometimes you need a compact payload.
3) 格式化、压缩与验证
- Format — add indentation for humans.
- Minify — compress into one line.
- Validate — check syntax without rewriting.
格式化工具不修复数据含义——只处理语法。
4) 常见错误
- Trailing commas:
{"a":1,} - Single quotes:
{'a':1} - Unquoted keys:
{a:1} - Comments inside JSON
- Mixing JSON with JS objects or YAML

6) 常见问题
Is it safe to paste sensitive data?
Processing happens in your browser. Still avoid pasting passwords unless necessary.
How is this different from editor beautify?
Same idea — useful when you need a quick check without opening an IDE.
Can I edit JSON in the field?
Yes. After edits, click Validate or Format again.
