excel 쓰기 보호(비열기 보호)의 해독 방법

excel은 쓰기 보호(비열기 보호)의 해독 방법으로 인터넷에서 excel 열기 보호에 대한 해독 도구가 매우 많지만 쓰기 보호에 대한 해독 소프트웨어가 없습니다.
실측을 통해 100% 유효하고 excel 2003에 국한되며 다른 버전은 시도하지 않았습니다. 본고는 무우애미망 www.51aimei.com 직접 측정할 수 있습니다. 원본 코드는 네트워크에서 유래한 것으로 작성자에게 감사를 드립니다.
방법:
1\파일 열기
2\도구 --- 매크로 --- 새 매크로 기록 --- 이름 입력: aa
3\기록 중지 (빈 매크로 얻기)
4\도구 --- 매크로 --- 매크로, aa 선택, 점 편집 단추
5\창의 모든 문자를 삭제하고 (몇 개만) 다음 내용으로 바꿉니다. (복사하십시오.)
6\편집 창 닫기
7\도구---매크로---매크로, AllInternalPasswords를 선택하고 실행, 두 번 확인, 2분만 기다리면 마우스가 깔때기 모양으로 변한다. 상관하지 말고 풀고 나서 확인하면 된다.오케이, 비밀번호 없어!!
8. 또 하나는 해독 과정 중간에 n개의 알림 상자가 있는데 그 중 하나는 비밀번호가 노출될 수 있다는 것을 명심해라.
내용은 다음과 같습니다.
