Cuối cùng, thực thi đoạn Macro này bằng cách:
Click menu View > Macros > View Macros >> Run
Bạn chờ khoảng 5s để đoạn Macros làm việc.
Password của file exel sẽ được hiện lên, bạn hãy ghi lại nếu cần:
Cuối cùng, thông báo hiện lên toàn bộ password, protected của worksheet của file exel đã bị vô hiệu hóa, ban có thể chỉnh sửa thoải mái rồi đấy.
Vậy là xong rồi, chúc bạn thành công nhé. Congtoan đã thử trên file word 2003, 2007 đều được. Có gì khó khăn comment để được giải đáp nhé.
