myRow = Range(Cells(3, 1), Cells(3, 1).End(xlDown)).Count + 2 'first two rows are headers However you're implicitly referring to whatever the ActiveSheet is everywhere else outside this With block. I makes ActiveSheet references explicit, and that's very good. In fact, there's little to no reason at all to ever declare anything As Integer in 2019: processors are optimized to deal with 32-bit integer types, and that's a Long in VBA.
HOW DO I MERGE DUPLICATE ROWS IN EXCEL CODE
This means as soon as your data involves row 32,768 and beyond, your code breaks with an "Overflow" run-time error. An Integer is a 16-bit signed integer type, so its maximum possible value is 32,767.
HOW DO I MERGE DUPLICATE ROWS IN EXCEL HOW TO
Use an indenter if you're unsure how to keep indentation consistent.

and then suddenly went way out there: Range(Cells(myFirstRow, 1), Cells(myFirstRow, m圜ol - 3)).HorizontalAlignment = xlCenter Proper indentation also helps, massively. Fortunately you can completely prevent this, by simply specifying Option Explicit at the very top of every module you ever write any VBA code in. This is extremely bug-prone, you don't want to allow VBA code to run with undeclared variables. and that iRow and n aren't declared at all. If you declare variables where you first assign them, as you need to introduce them, then you simply can't miss the fact that m圜ell, myRange, rngPaste are never assigned or referenced anywhere. Truth is, it only makes you scroll back and forth all the time for no reason, and makes it much harder than it should be, to know whether or not a variable is used, let alone where it's used. "I can see everything that's used in the procedure at once" sounds great on paper. People defending this "declare everything at the top of the procedure" habit usually defend it pretty hard, and they're wrong. This procedure is somewhere between 2 and 3 screens high on my laptop: when I'm at the bottom of the procedure, I don't know what I'm looking at, so I scroll back up to this wall of declarations, parse the chunk of code, locate the variable I'm looking for, then scroll back down to where I was. Would be very grateful for any code optimizations!ĭon't do this. Merging only when the "base/initial" cell is not the same as a "check" cell and merge all appropriate cells all together (not by each row), but I can't find a way to make it work. I tried to create a different logic to initiate "merge" by blocks (skip merging the same value cells in the first column right away): Range(Cells(myFirstRow + i - 1, k), Cells(myFirstRow + i, k)).EntireRow.AutoFit Range(Cells(myFirstRow + i - 1, 8), Cells(myFirstRow + i, 8)).WrapText = True Range(Cells(myFirstRow + i - 1, k), Cells(myFirstRow + i, k)).VerticalAlignment = xlCenter Range(Cells(myFirstRow + i - 1, k), Cells(myFirstRow + i, k)).HorizontalAlignment = xlCenter

Range(Cells(myFirstRow + i - 1, k), Cells(myFirstRow + i, k)).Merge N = Cells(myFirstRow + i + 1, myFirstColumn)įor k = 1 To m圜ol - 3 'need to merge data per column but don't need to merge data in the last 3 columns IRow = Cells(myFirstRow + i, myFirstColumn) Range(Cells(myFirstRow, 1), Cells(myFirstRow, m圜ol - 3)).EntireRow.AutoFit Range(Cells(myFirstRow, 8), Cells(myFirstRow, 8)).WrapText = True Range(Cells(myFirstRow, 1), Cells(myFirstRow, m圜ol - 3)).VerticalAlignment = xlCenter Range(Cells(myFirstRow, 1), Cells(myFirstRow, m圜ol - 3)).HorizontalAlignment = xlCenter Set n = Cells(myFirstRow + 1, myFirstColumn) Set iRow = Cells(myFirstRow, myFirstColumn) 'Apply formatting to the end of the table: MyRow = Range(Cells(3, 1), Cells(3, 1).End(xlDown)).Count + 2 'first two rows are headers I wrote a VBA code and it works but it works very slow as it executes "merge" function per each row no matter if consequent cells are the same or different. Need to merge data per column if records in the first column are the same.
