批量文件编码转换工具

import chardet, os, glob, shutil def detect_encoding(file): with open(file, 'rb') as f: result = chardet.detect(f.read(100000)) return result['encoding'] input_dir = 'files' for f in glob.glob(os.path.join(input_dir, '*.txt'), recursive=True): enc = detect_encoding(f) if enc and enc.lower() != 'utf-8': print(f'{f}: {enc} -> UTF-8') shutil.copy(f, f + '.bak') # 备份 with open(f, 'r', encoding=enc, errors='replace') as src: content = src.read() with open(f, 'w', encoding='utf-8') as dst: dst.write(content) print('编码转换完成')

1.安装Python 3.7+
2.pip install chardet
3.保存为convert_encoding.py
4.修改目标文件夹和文件类型
5.python convert_encoding.py 运行
自动识别文件编码
转换前自动备份原文件
可以指定文件扩展名过滤
支持递归子文件夹
已经是UTF-8的文件会跳过
