It will depend upon what else you have in your spreadsheet. Text like "Minutes(Cardinal)" might require care. First I would have the formulae visible (View, All formulae or Ctrl+`).
Then it rather depends upon the formulae, of which you have only provided a single example. A column as the example that had been copied down could be changed with simple Edit, Find and Replace.... of
;$C, with Also search within formulae.
With two columns the same (say
Cs and also
Ds), Search using regular expressions could be applied to save repeating the above for
Ds, with finding:
and in both cases replacing with:
Two columns for example, but it could be the whole sheet. Unfortuantely that regex introduces spaces into the formulae, though those can then be removed quite easily and in bulk.
So possible, but a peculiar requirement for which they may be a better alternative solution.
