Jsonlint

这是基于Python3的终端JSON工具集，核心功能含语法校验、格式化美化、压缩、深度对比文件、列顶级键、按路径提取嵌套值。适用于配置文件检查、API响应格式化、部署前压缩、版本对比等场景，通过终端命令调用，输出直观的结果信息。

JSONLint

A real JSON linter and toolkit for the terminal. Validate syntax, pretty-print, minify, compare files, list keys, and extract values by path — all powered by python3.

Commands

Command	Description
`jsonlint validate <file>`	Check JSON syntax — reports type, element count, file size, and shows error context on failure
`jsonlint format <file>`	Pretty-print JSON with 4-space indentation
`jsonlint minify <file>`	Compact JSON (remove all whitespace), shows bytes saved
`jsonlint diff <file1> <file2>`	Deep structural comparison of two JSON files — shows added, removed, and changed values with dot-paths
`jsonlint keys <file>`	List all top-level keys with types and value previews
`jsonlint extract <file> <path>`	Extract a value by dot-path (e.g. `config.database.host`), supports array indices like `items[0]`

Requirements

python3 (uses json stdlib module)

Examples

# Validate a config file
jsonlint validate config.json

# Pretty-print API response
jsonlint format response.json

# Minify for deployment
jsonlint minify package.json

# Compare two versions
jsonlint diff old.json new.json

# List what's in a JSON file
jsonlint keys data.json

# Dig into nested values
jsonlint extract config.json database.host
