JSON Formatter & Validator
格式化、验证和美化 JSON 数据。
Formatted JSON will appear here...JSON Formatter 是一款免费的浏览器工具，可即时美化或压缩 JSON 数据。它解析原始 JSON 字符串，检查语法错误，并应用适当的缩进和语法高亮，使即使是深度嵌套的结构也易于阅读。
将 JSON 粘贴到输入框中，点击「格式化」可获得带缩进的输出，点击「压缩」可将其压缩成一行以用于生产环境。验证器会精确指出语法错误的位置，方便快速修正。
该工具完全在浏览器中运行，不会将任何数据发送到服务器。非常适合调试 API 响应、编辑配置文件以及在发送给服务之前准备 JSON 有效负载。

import json
# Format (pretty-print) a JSON string
raw = '{"name":"Alice","age":30,"hobbies":["reading","coding"]}'
data = json.loads(raw)
# Indent with 2 spaces
pretty = json.dumps(data, indent=2)
print(pretty)
# {
# "name": "Alice",
# "age": 30,
# "hobbies": ["reading", "coding"]
# }
# Sort keys alphabetically
sorted_json = json.dumps(data, indent=2, sort_keys=True)
# Minify (compact)
minified = json.dumps(data, separators=(',', ':'))
print(minified)
# {"name":"Alice","age":30,"hobbies":["reading","coding"]}
# Format a JSON file in-place
