использовать userinput для действий

Question

I want to make open worksheets which user write in inputbox. There are 20 worksheets to choose from. without declaring each worksheet in code for ex. If userentry= ".xlsx" for each worksheet, How can I do it easy way?

I wrote vba code for each worksheet but wrote worksheet name manually.

подпрограмма openworksheet () просит пользователя написать имя открываемой книги.Подпрограмма Copy_OperationalDowntime_Data () копирует данные и вставляет их в открытый файл vba и копирует файл data.xlsm.Та же операция копирования и вставки выполняется для всех подпрограмм, и данные вставляются в открытый файл vba и копируют файл data.xlsm.

Public Sub openworksheet()
'open RTM
Dim usersel, userentry, worksheetpath, worksheetname, nameofws As String
    usersel = MsgBox("enter the date of the worksheet you would like to open") & vbCrLf & _
                    "enter file name in the format 20 Jun 19 RTM.xlsm"
    userentry = InputBox(usersel, vbOKCancel)
    worksheetpath = "C:\Users\DESHARMA\Desktop\"
    worksheetname = worksheetpath & userentry
    nameofws = worksheetname
    Workbooks.Open Filename:=nameofws
End Sub

Public Sub Copy_OperationalDowntime_Data()
    Dim keepdata As String

I am not sure how to refer user entered workbook name.
