Usage Scenarios

Scenario 1: Format a JSON File with Proper Indentation

User input: "Format this JSON file with 4-space indentation" Expected output: The tool reads input.json, applies 4-space indentation, and outputs the formatted JSON to stdout or a specified output file.

Scenario 2: Validate JSON Syntax

User input: "Check if my config.json has valid JSON syntax" Expected output: The tool validates the file and returns "Valid JSON" or an error message with the line number of the syntax issue.

Scenario 3: Format and Sort Keys Alphabetically

User input: "I want this JSON formatted with sorted keys" Expected output: The tool reads the JSON file, formats it with default 2-space indentation, sorts all keys alphabetically, and outputs the result.

Scenario 4: API返回的数据太乱了要格式化

User input: "后端给了一个API返回的JSON数据，字符串一长串看了头晕，帮我格式化成可读的格式，顺便检查一下语法对不对。" Expected output: 接收原始JSON字符串：1）进行语法验证并指出错误位置（如多余的逗号、未闭合的引号、不合法的数值）；2）输出格式化后的JSON（缩进2空格/4空格可选）；3）如果支持，还可提供JSON路径查询、键值对统计和一键复制功能。支持嵌套最大深度检测，避免循环引用导致的卡顿。

Description

A utility skill for formatting JSON files with proper indentation and validating JSON syntax. Supports reading from files or stdin, outputting to files or stdout.

Usage

# Format a JSON file (pretty-print to stdout)
python ~/.openclaw/skills/json-formatter-pro/json_formatter.py format input.json

# Format and save to a new file
python ~/.openclaw/skills/json-formatter-pro/json_formatter.py format input.json -o output.json

# Validate JSON syntax without formatting
python ~/.openclaw/skills/json-formatter-pro/json_formatter.py validate input.json

# Read from stdin, format and output to stdout
cat input.json | python ~/.openclaw/skills/json-formatter-pro/json_formatter.py format -

# Validate JSON from stdin
cat input.json | python ~/.openclaw/skills/json-formatter-pro/json_formatter.py validate -

Options

  • format: Pretty-print JSON with proper indentation
  • validate: Check if JSON is valid without formatting output
  • -o, --output: Specify output file (default: stdout)
  • -i, --indent: Number of spaces for indentation (default: 2)
  • --sort-keys: Sort JSON keys alphabetically

Examples

# Format with 4-space indentation
python ~/.openclaw/skills/json-formatter-pro/json_formatter.py format data.json -i 4

# Format and sort keys
python ~/.openclaw/skills/json-formatter-pro/json_formatter.py format data.json --sort-keys

# Validate a JSON file
python ~/.openclaw/skills/json-formatter-pro/json_formatter.py validate config.json
# Output: Valid JSON or error message with line number

Exit Codes

  • 0: Success
  • 1: Invalid JSON syntax
  • 2: File not found or permission error
  • 3: Other error
