excel-interop

I have a lot of excel files that contains data and it contains empty rows and empty columns. like shown bellow I am trying to remove Empty rows and columns from excel using interop. I create a simple winform application and used the following code and it works fine. Dim lstFiles As New List(Of String) lstFiles.AddRange(IO.Directory.GetFiles(m_strFolderPath, "*.xls", IO.SearchOption.AllDirectories)) Dim m_XlApp = New Excel.Application Dim m_xlWrkbs As Excel.Workbooks = m_XlApp.Workbooks Dim m_xlWrkb As Excel.Workbook For Each strFile As String In lstFiles m_xlWrkb = m_xlWrkbs.Open(strFile) Dim
