How can I speed this vba code up which involves formatting?

Question

I am setting up a new pricing schedule which reads selected information from a 'Register' tab, based on selected criteria, and copying this into a new tab. This data is formatted so it looks aesthetically pleasing. I am finding formatting the code is slowing down the run speed significantly. If possible I would like to speed this up as I will be iterating this multiple times.

I hae sped the program up a reasonable amount. Initially it took 30s, whereas now it is about 10s. I have followed information from this website as best as I can: https://www.soa.org/News-and-Publications/Newsletters/Compact/2012/january/com-2012-iss42-roper.aspx

I feel there is still scope to improve more, though I am unsure how, and am reaching out to see if there is, or are, better ways to improve the code so it runs quicker.

I found a few lines that could save you some execution time.

'****EDIT****Changed this to direct range reference rather than go through the Names collection.
'Set namedRange1 = file1.Names("Client_Register").RefersToRange
'Set namedRange2 = file1.Names("Pricing_Range").RefersToRange
Set namedRange1 = file1.Range("Client_Register")
Set namedRange2 = file1.Range("Pricing_Range")

Used range takes more time rather use .cells directly

'delete everything from the pricing schedule/reset
'****EDIT***
With ws2 'Sheets("Pricing Schedule")
    'used range takes more time rather use .cells directly
    .Cells.ClearContents

Rather than use arrays you can directly update values as shown below

'I am using i for the row count
        ws2.Range("B" & i + 6).Value = namedRange1.Cells(i, 5).Value
        ws2.Range("C" & i + 6).Value = namedRange1.Cells(i, 4).Value
        ws2.Range("D" & i + 6).Value = namedRange1.Cells(i, 6).Value
        ws2.Range("E" & i + 6).Value = namedRange1.Cells(i, 10).Value
        ws2.Range("F" & i + 6).Value = namedRange1.Cells(i, 11).Value
        ws2.Range("G" & i + 6).Value = namedRange1.Cells(i, 12).Value
        ws2.Range("H" & i + 6).Value = namedRange1.Cells(i, 12).Value
        ws2.Range("I" & i + 6).Value = namedRange1.Cells(i, 16).Value
        ws2.Range("J" & i + 6).Value = namedRange1.Cells(i, 9).Value
        ws2.Range("K" & i + 6).Value = namedRange1.Cells(i, 8).Value
        i = i + 1

The main culprit for your slower performance is the insert operation. try to work the logic to not having insert. If not possible, try to insert rows outside the loop in a single operation rather than in the loop

        Range("Pricing_Range").Rows(i + 1).Insert Shift:=xlShiftDown
        Range("Pricing_Range").Rows(i + 1).Insert Shift:=xlShiftDown

Example of With and block assignment from an array:

'copy from database to the pricing schedule as a 
'   non formatted list of all the info - this runs quickly, 
'   but I am open to changing it
With Range("Client_Register")

    For Each rw In .Rows
        If .Cells(rw.Row, 2) = selectedClient Then

            collect(i, 1) = .Range("E" & rw.Row)
            collect(i, 2) = .Range("D" & rw.Row)
            collect(i, 3) = .Range("F" & rw.Row)
            collect(i, 4) = .Range("J" & rw.Row)
            collect(i, 5) = .Range("K" & rw.Row)
            collect(i, 6) = .Range("L" & rw.Row)
            collect(i, 7) = .Range("M" & rw.Row)
            collect(i, 8) = .Range("P" & rw.Row)
            collect(i, 9) = .Range("I" & rw.Row)
            collect(i, 10) = .Range("H" & rw.Row)

            'you could even skip the row-by-row population of values
            '  and assign as a block after exiting the loop
            ws2.Range("B" & i + 6).Resize(1, 10).Value = _
                    Array(collect(i, 1), collect(i, 2), collect(i, 3), _
                          collect(i, 4), collect(i, 5), collect(i, 6), _
                          collect(i, 7), collect(i, 8), collect(i, 9), _
                          collect(i, 10))

            i = i + 1
        End If
    Next

End With

Note this will break if your Client_Register refers to a range which doesn't start on Row1, because of the relative range references.

Eg:

 Range("A1:A10").Range("A1") 'refers to A1
 Range("A2:A10").Range("A1") 'refers to A2

Answer 3

Your handling of the collect array is inefficient. Consider reading the entire Client Register into an array with MyArray = Range.Value. Then prepare the output array in memory and write it to the worksheet after all looping is done, in one go, with TargetRange.Value = collect.

Avoid inserting rows. What's wrong with the existing? If you are preparing all data in an array to be pasted to the worksheet, empty array elements will produce empty worksheet cells. In this way all inserting can be avoided and all you need to do is to format.

There is time cost for every access to the worksheet, whether to read or write. Even for formatting, try to create ranges that are treated in the same manner. Avoid accessing the worksheet in loops.
