((此方法只對保護工作表有用而已))
若是於選項→安全性→保護密碼~~就只能用軟體來解囉！(如開啟excel就叫你輸入密碼)
Excel 2007密碼保護的解除方法VBA巨集程式破解法：
第一步：打開該文件，切換到“檢視”選項，點擊“巨集”→“錄製巨集”，出現“錄製巨集”窗口，在“巨集名稱”打上：PasswordBreaker，點擊“確定”退出；
第二步：再點擊“巨集”→“檢視巨集”，選擇“巨集名稱”下的“PasswordBreaker”並點擊右邊的“編輯”，會自動打開“Microsoft Visual Basic”編輯器，用以下的內容完全替換右側窗口中的所有編碼：
Sub PasswordBreaker()
Dim i As Integer, j As Integer, k As Integer
Dim l As Integer, m As Integer, n As Integer
Dim i1 As Integer, i2 As Integer, i3 As Integer
Dim i4 As Integer, i5 As Integer, i6 As Integer
On Error Resume Next
For i = 65 To 66: For j = 65 To 66: For k = 65 To 66
For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66
For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66
For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126
ActiveSheet.Unprotect Chr(i) & Chr(j) & Chr(k) & _
Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _
Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
If ActiveSheet.ProtectContents = False Then
MsgBox "One usable password is " & Chr(i) & Chr(j) & _
Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
ActiveWorkbook.Sheets(1).Select
Range("a1").FormulaR1C1 = Chr(i) & Chr(j) & _
Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
Exit Sub
End If
Next: Next: Next: Next: Next: Next
Next: Next: Next: Next: Next: Next
End Sub
第三步：再點擊“巨集”→“檢視巨集”，選擇“巨集名稱”下的“PasswordBreaker”並點擊“執行”，密碼就現形了。
第四步：切換“校閱”選項，點擊“保護工作表”，然後輸入密碼即可解除鎖定。
照表操作~保證無誤！測試ok~

第三步：檢視→最下面您的microsoft excel→
工具→巨集→巨集→執行 ((等待...等待...再等待............ZZZzzzz都快睡著了！時間會有點久))
出現密碼！有大小寫之分。(其實解開後就可以改內容啦！)
再開啟鎖起來的excel輸入解開的密碼，((工具→保護→取消保護工作表→密碼))
