How do I find and Replace in anouther excel document

I am tring to create a macro (in Excel) to open another excel worksheet, do a find-replace, then save it.

I have already achieved this with a word document like this:

...
Dim wrdDoc As Word.Document
If wrdApp Is Nothing Then Set wrdApp = CreateObject("Word.Application")
Set wrdDoc = wrdApp.Documents.Open(TemplateFilePath)
...

Call WordReplace(wrdDoc,"a","b")

....

Private Sub WordReplace(wrdDoc As Word.Document, sFind As String, sReplace As String)
  With wrdDoc.Content.Find
    .Text = sFind
    .Replacement.Text = sReplace
    .Forward = True
    .Wrap = wdFindContinue
    .Format = False
    .MatchCase = False
    .MatchWholeWord = False
    .MatchWildcards = False
    .MatchSoundsLike = False
    .MatchAllWordForms = False
    .Execute Replace:=wdReplaceAll
  End With
End Sub

I have crudely tried to replace the word "Word" with "Excel" in the above code to no avail.

Can somone point me in the 开发者_Go百科right direction please?

You could do:

Sub a()

Dim excDoc As Workbook
....

Set excDoc = Workbooks.Open("c:\mata.xls")
Call WordReplace(excDoc, "a", "b")
....
End Sub

Private Sub WordReplace(excDoc As Variant, sFind As String, sReplace As String)

Dim sht As Worksheet

For Each sht In excDoc.Worksheets
  With sht
       .Cells.Replace What:=sFind, Replacement:=sReplace, LookAt:=xlWhole, _
        SearchOrder:=xlByRows, MatchCase:=True, SearchFormat:=False, _
        ReplaceFormat:=False
  End With
Next
End Sub
