Unprotect Password Excel 2007

Anda mungkin sudah tahu betapa mudahnya untuk melindungi Microsoft Office Excel worksheet dan workbook dari perubahan tidak sah dengan bantuan password. Tapi, apa yang harus dilakukan jika Anda tidak dapat mengingat password yang Anda gunakan untuk melindungi atau Anda download sebuah excel dari internet dan ingin memiliki melihat rumus atau informasi yang diembed – tetapi semua bahwa data mungkin tidak dapat diakses karena proteksi password.

Saya memiliki metode yang sangat sederhana dengan mana Anda dapat dengan mudah dapat memulihkan password dan juga un-melindungi worksheet atau workbook. Harap dicatat: metode ini hanya akan menghapus perlindungan dari file excel dan bukan password yang digunakan untuk membuka file excel itu sendiri.

Buka file excel yang dilindungi password dan goto s Makro (Saya menggunakan Office 2007 sehingga menu itu Macro View mungkin berbeda >>). Klik “record macro >> OK” dan kemudian klik pada “Stop Recording” dari menu yang sama. Sekarang goto “Macro View”, Anda akan menemukan Makro dengan Misalnya nama default Macro1 – Pilih nama makro dan klik Edit. Sekarang Visual Basic Editor membuka. Re-tempat kode default dan Paste kode di bawah ini.

Sub Macro1()
