I though this would be trivial; turns out it’s not.

  • When you copy a formula from the clipboard, relative references are adjusted, so Range(x).Formula=Range(y).Formula doesn’t produce the expected results.
    The correct way is Range(x).Formula=Range(y).FormulaR1C1. Easy once you’ve been there.
  • Copying border formats with Range(x).Borders=Range(y).Borders crashes Excel. You have to copy each individual border, left, right, top, etc.
  • Similarly for fonts, you have to copy the font attributes one by one.
  • Good practice: check that the areas have compatible sizes and don’t overlap.

Nothing inordinately difficult, but time-consuming to get right. Here’s the code:

Option Explicit

' Copy cells without using the clipboard.
' Source is a range from which to copy values/formulas/formats.
' Dest is the destination range. Must be either
'     a single cell, the top-left of the target range. The source size (rows x columns) is copied.
'   or
'     a range exactly the same size as source. We throw an error if the shapes don't match.
' If 'what' is omitted, copies the values.
' what=CopyFormulas copies the formulas instead of the values.
' what=CopyFormats copies the formats.
' what=CopyFormulas+CopyFormats copies both.
' Examples:
'   CopyCells Range("b2:c6"), Range("h10")                                   ' Copies 8 cells (6x2) from B2 to H10
'   CopyCells Range(cells(2,2),cells(6,3)), Range("h10")                     ' Idem
'   CopyCells Range(cells(2,2),cells(6,3)), Range(cells(10,10),cells(14,12)) ' Fails, source is 6x2, dest is 6x3
'   CopyCells Range("b2:c6"), Range("b3")                                    ' Fails, source and dest intersect
