That's the trouble with using CTRL + C and CTRL + V (copy and paste).
But there is a very reliable means I use to duplicate Excel sheets, it makes the exact copy of the sheet - no color difference, row and column widths are same, and values won't change.
It is my preferred means of making copies of a sheet I want to analyse or extracting a sheet I want to send to client/colleague.
So let's go.
I'll rightclick on the Output sheet tab.
I'll click on Move or Copy.
I'll tick the Create a Copy box. (But for move operation, leave it unticked)
In the To book dropbox, I'll indicate a New Book
Finally, I'll click on OK.
And I'll get a copy of the Output sheet
