Mengunci Workbook dalam Excel berguna untuk melindungi konten data yang terdapat dalam setiap sheet tersebut agar tidak bisa diubah atau dimodifikasi orang lain.
Pada postingan tentang Cara Membuka Worksheet Yang Terproteksi menjelaskan bagaimana membuka kembali worksheet yang terkunci jika Anda lupa pasword nya dan kali ini menjelaskan tentang membuka pasword untuk lembar kerja secara keseluruhannya.
          Sekarang bagaimanakah jika password yang digunakan untuk mengunci workbook tersebut lupa atau tidak ingat, sehingga file tersebut tidak bisa dimodifikasi atau dipakai sama sekali.
Nah untuk membuka workbook Excel yang terkunci, ada cara untuk membuka password tersebut, ikuti langkah-langkah sebagai berikut:

Buka File Excel dimana Workbook tersebut diproteksi.


Lalu buka Visual Basic (Alt+F11), dan klik Insert dan klik Module.


Kemudian copy-kan syntax VBA berikut ini ke dalam Module tersebut:

Public Sub AllInternalPasswords()
        ' Breaks worksheet and workbook structure passwords. Bob McCormick 
        '  probably originator of base code algorithm modified for coverage 
        '  of workbook structure / windows passwords and for multiple passwords

        ' Norman Harker and JE McGimpsey 27-Dec-2002 (Version 1.1)
        ' Modified 2003-Apr-04 by JEM: All msgs to constants, and
        '   eliminate one Exit Sub (Version 1.1.1)

        MsgBox ALLCLEAR & AUTHORS & VERSION & REPBACK, vbInformation, HEADER
    End Sub

Setelah itu aktifkan Tools dan klik Macros, setelah terbuka jendela Macros aktifkan AllInternalPasswords dan klik Run


Biarkan system bekerja beberapa saat dan akan muncul pesan sebagai berikut:


Laluklik OK dan tutup program Visual Basic, maka workbook yang tadinya terkunci dapat dimodifikasi atau ditulis lagi.
