"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Here you go.
Imports Excel = Microsoft.Office.Interop.Excel
Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, _ByVal e As System.EventArgs) Handles Button1.Click

        Dim xlApp As Excel.Application
        Dim xlWorkBook As Excel.Workbook
        Dim xlWorkSheet As Excel.Worksheet
        Dim range As Excel.Range
        Dim rCnt As Integer
        Dim cCnt As Integer
        Dim Obj As Object

        xlApp = New Excel.ApplicationClass
        xlWorkBook = xlApp.Workbooks.Open("c:\vbexcel.xlsx")
        xlWorkSheet = xlWorkBook.Worksheets("sheet1")

        range = xlWorkSheet.UsedRange

        For rCnt = 1 To range.Rows.Count
            For cCnt = 1 To range.Columns.Count
                Obj = CType(range.Cells(rCnt, cCnt), Excel.Range)
                //Here, check if the Cell i.e Obj.value has x and do whatever you want.

    End Sub

End Class

How do you want the returned words? Do you want an array of words containing "x", or a Range object of all cells containing words with "x"?

Either way, you'd use the Range.Find method which is much more efficient than looping through all cells.
