网上下载了工作簿，发现居然有密码!xxoo，既然放网上干嘛要加密码啊?!后来网上找到使用VBA破解工作表密码的方法，拿来分享。首先，尝试打开工作簿时，提示有密码：使用快捷键Ctrl+F11键，打开VBA编辑界面，点击“插入”菜单下的子菜单“模块”：在模块编辑器中输入以下代码：OptionExplicitPublicSubAllInternalPasswords()ConstDBLSPACEAsString=vbnewline&vbnewlineConstAUTHORSAsString=DBLSPACE&vbnewline&_AdaptedfromBobMcCormickbasecodeby&_NormanHarkerandJEMCGImpseyConstHEADERAsString=AllInternalPasswordsUserMessageConstVERSIONAsString=DBLSPACEConstREPBACKAsString=DBLSPACE&Pleasereportfailure&_tothemicrosoft.public.Excel.programmingnewsgroup.ConstALLCLEARAsString=DBLSPACE&Theworkbookshould&_nowbefreeofallpasswordprotection,somakesureyou:&_DBLSPACE&SAVEITNOW!&DBLSPACE&andalso&_DBLSPACE&BACKUP!,BACKUP!!,BACKUP!!!&_DBLSPACE&Also,rememberthatthepasswordwas&_putthereforareason.Don'tstuffupcrucialformulas&_ordata.&DBLSPACE&Accessanduseofsomedata&_maybeanoffense.Ifindoubt,don't.ConstMSGNOPWORDS1AsString=Therewerenopasswordson&_sheets,orworkbookstructureorwindows.&AUTHORS&VERSIONConstMSGNOPWORDS2AsString=Therewasnoprotectionto&_workbookstructureorwindows.&DBLSPACE&_Proceedingtounprotectsheets.&AUTHORS&VERSIONConstMSGTAKETIMEAsString=AfterpressingOKbuttonthis&_willtakesometime.&DBLSPACE&Amountoftime&_dependsonhowmanydifferentpasswords,the&_passwords,andyourcomputer'sspecification.&DBLSPACE&_Justbepatient!Makemeacoffee!&AUTHORS&VERSIONConstMSGPWORDFOUND1AsString=YouhadaWorksheet&_StructureorWindowsPasswordset.&DBLSPACE&_Thepasswordfoundwas:&DBLSPACE&$$&DBLSPACE&_Noteitdownforpotentialfutureuseinotherworkbooksby&_thesamepersonwhosetthispassword.&DBLSPACE&_Nowtocheckandclearotherpasswords.&AUTHORS&VERSIONConstMSGPWORDFOUND2AsString=YouhadaWorksheet&_passwordset.&DBLSPACE&Thepasswordfoundwas:&_DBLSPACE&$$&DBLSPACE&Noteitdownforpotential&_futureuseinotherworkbooksbysamepersonwho&_setthispassword.&DBLSPACE&Nowtocheckandclear&_otherpasswords.&AUTHORS&VERSIONConstMSGonLYONEAsString=onlystructure/windows&_protectedwiththepasswordthatwasjustfound.&_ALLCLEAR&AUTHORS&VERSION&REPBACKDimw1AsWorksheet,w2AsWorksheetDimiAsInteger,jAsInteger,kAsInteger,lAsIntegerDimmAsInteger,nAsInteger,i1AsInteger,i2AsIntegerDimi3AsInteger,i4AsInteger,i5AsInteger,i6AsIntegerDimPWord1AsStringDimShTagAsBoolean,WinTagAsBooleanApplication.ScreenUpdating=FalseWithActiveWorkbookWinTag=.ProtectStructureOr.ProtectWindowsEndWithShTag=FalseForEachw1InWorksheetsShTag=ShTagOrw1.ProtectContentsNextw1IfNotShTagAndNotWinTagThenMsgBoxMSGNOPWORDS1,vbInformation,HEADERExitSubEndIfMsgBoxMSGTAKETIME,vbInformation,HEADERIfNotWinTagThenMsgBoxMSGNOPWORDS2,vbInformation,HEADERElseOnErrorResumeNextDo'dummydoloopFori=65To66:Forj=65To66:Fork=65To66Forl=65To66:Form=65To66:Fori1=65To66Fori2=65To66:Fori3=65To66:Fori4=65To66Fori5=65To66:Fori6=65To66:Forn=32To126WithActiveWorkbook.UnprotectChr(i)&Chr(j)&Chr(k)&_Chr(l)&Chr(m)&Chr(i1)&Chr(i2)&_Chr(i3)&Chr(i4)&Chr(i5)&Chr(i6)&Chr(n)If.ProtectStructure=FalseAnd_.ProtectWindows=FalseThenPWord1=Chr(i)&Chr(j)&Chr(k)&Chr(l)&_Chr(m)&Chr(i1)&Chr(i2)&Chr(i3)&_Chr(i4)&Chr(i5)&Chr(i6)&Chr(n)MsgBoxApplication.Substitute(MSGPWORDFOUND1,_$$,PWord1),vbInformation,HEADERExitDo'Bypassallfor...nextsEndIfEndWithNext:Next:Next:Next:Next:NextNext:Next:Next:Next:Next:NextLoopUntilTrueOnErrorGoTo0EndIfIfWinTagAndNotShTagThenMsgBoxMSGONLYONE,vbInformation,HEADERExitSubEndIfOnErrorResumeNextForEachw1InWorksheets'AttemptclearancewithPWord1w1.UnprotectPWord1Nextw1OnErrorGoTo0ShTag=FalseForEachw1InWorksheets'ChecksforallclearShTagtriggeredto1ifnot.ShTag=ShTagOrw1.ProtectContentsNextw1IfShTagThenForEachw1InWorksheetsWithw1If.ProtectContentsThenOnErrorResumeNextDo'DummydoloopFori=65To66:Forj=65To66:Fork=65To66Forl=65To66:Form=65To66:Fori1=65To66Fori2=65To66:Fori3=65To66:Fori4=65To66Fori5=65To66:Fori6=65To66:Forn=32To126.UnprotectChr(i)&Chr(j)&Chr(k)&_Chr(l)&Chr(m)&Chr(i1)&Chr(i2)&Chr(i3)&_Chr(i4)&Chr(i5)&Chr(i6)&Chr(n)IfNot.ProtectContentsThenPWord1=Chr(i)&Chr(j)&Chr(k)&Chr(l)&_Chr(m)&Chr(i1)&Chr(i2)&Chr(i3)&_Chr(i4)&Chr(i5)&Chr(i6)&Chr(n)MsgBoxApplication.Substitute(MSGPWORDFOUND2,_$$,PWord1),vbInformation,HEADER'leveragefindingPwordbytryingonothersheetsForEachw2InWorksheetsw2.UnprotectPWord1Nextw2ExitDo'Bypassallfor...nextsEndIfNext:Next:Next:Next:Next:NextNext:Next:Next:Next:Next:NextLoopUntilTrueOnErrorGoTo0EndIfEndWithNextw1EndIfMsgBoxALLCLEAR&AUTHORS&VERSION&REPBACK,vbInformation,HEADEREndSub点击运行：破解过程需要几分钟，有几次对话框弹出，都是英文的，留意对话框中如下内容：标注部分即为密码。虽然不是原始密码，但是用这个密码照样可以打开工作簿的。在线ERP文章经过精心编写发布，转载请留名，谢谢！
