Cara membobol / membuka password dokumen excel yang diprotect

Hai Sobat EPG, kali ini saya akan posting tentang Cara membobol / membuka dokumen excel yang di protect , Sesuai pengalaman saya sendiri, saya pernah mendapat tugas untuk mengerjakan di Ms Excel, saat itu guru saya memprotect (memberi password) file / dokumen tsb. Berbagai cara telah saya lakukan namun tidak ada yang berhasil, ada cara yang berhasil yakni meng-copy file / dokumen tsb ke blank document baru, tapi cara tersebut salah / kurang tepat, nah lebih tepatnya lagi jika anda membobolnya... Disini saya sedikit sharing bagaimana cara membobol dokumen yang di protect, oke langsung saja,

Berikut contoh gambar file yang di protect oleh guru saya :

Nah, berikut cara mengatasinya :) Cekidot :

1) Pertama-tama, buka file excel anda yang diprotect 

2) Lalu, tekan tombol alt + f11 pada keyboard anda, seperti pada gambar berikut :

3) Bila sudah menekan tombol alt + f11, maka akan muncul visual basic seperti berikut :

4) Lalu klik 2x pada sheet yang ingin dibuka, misal saya tadi menekan tombol alt + f11 di sheet 4, berarti yang anda klik 2x harus sheet 4 tersebut, maka akan nampak seperti berikut jika sudah di klik 2x :

5) Nah, setelah itu anda masukkan kode html dibawah ini :
