当单个甚至单行Json文件大小超过100M时,无论是哪个文本编辑器在处理时都会显得吃力,接下来介绍一种非常方便的方式,快速格式化大型Json文件。
:::info Python 自带json-tool 在转换是会导致中文乱码,以下在原有基础上进行了优化,并增加中文支持 :::

"""
Command-line tool to validate and pretty-print JSON
Usage::
$ python3 json-tool.json import.json output.json
Need Python 3.

import argparse
import collections
import json
import sys
def main():
prog = 'python -m json.tool'
description = ('A simple command line interface for json module '
'to validate and pretty-print JSON objects.')
parser = argparse.ArgumentParser(prog=prog, description=description)
parser.add_argument('infile', nargs='?', type=argparse.FileType(),
help='a JSON file to be validated or pretty-printed')
parser.add_argument('outfile', nargs='?', type=argparse.FileType('w'),
help='write the output of infile to outfile')
parser.add_argument('--sort-keys', action='store_true', default=False,
help='sort the output of dictionaries alphabetically by key')
options = parser.parse_args()
infile = options.infile or sys.stdin
outfile = options.outfile or sys.stdout
sort_keys = options.sort_keys
with infile:
try:
if sort_keys:
obj = json.load(infile)
else:
obj = json.load(infile,
object_pairs_hook=collections.OrderedDict)
except ValueError as e:
raise SystemExit(e)
with outfile:
json.dump(obj, outfile, sort_keys=sort_keys, ensure_ascii=False, indent=2)
outfile.write('\n')
if __name__ == '__main__':
main()

将以上代码文件保存为 json-tool.json,然后使用 Python3 运行即可
python3 json-tool.json 190720_190730.json 06.json
