I need help getting the syntax right for a loop...

This is what I am trying to accomplish:
Start in A2, run spell check on that cell only.
Go to the next cell in that row with data (if any, up to the last column)
and run
spell check on that cell only.

Go to the next cell in that row with data (if any, up to the last last
column) run
spell check on that cell only...etc.
Then move to Row 3 and do the same...
Then Row 4...then 5...etc. Until we hit the last row.

Can someone help me get the syntax right? I know this is probably a ways
off, but this is where I left off. (As you can see..need a lot of help...it
obviously doesn't work).

Sub SpellCheck3()

Dim LastRow As Long
Dim LastCol As Long
LastRow = ActiveSheet.Cells(Rows.Count, "C").End(xlUp).Row
LastCol = ActiveSheet.Cells(1, Columns.Count).End(xlToLeft).Column
Debug.Print LastRow, LastCol
Set LastCell = ActiveSheet.Cells(LastRow, LastCol)

x = 2
z = 1

Do Until x = LastRow
Do Until z = LastCol
Set mc = ActiveSheet.Cells(x, z)
Application.Goto(ActiveSheet.Range(mc.convertformu la(formula:=mc,
FromReferenceStyle:=R1C1 _
, ToReferenceStyle:=A1)
Range(x.Address, z.Address).CheckSpelling SpellLang:=1033,
AlwaysSuggest:=True
z = z + 1
Loop
z = 1
x = x + 1
Loop
End Sub
