Hi all
I have code below to check balansheet then copy row with conditions
But I thinks this code too long and run slow, could you make this code shorter

Many thank

Code:

Return population for a City
If you have a list of cities in A2:A100, use Data, Geography. Then =A2.Population and copy down.

Three things that I know that speed up vba code:
1. Application.ScreenUpdating - You already have this one
2. Application.Calculation = xlManual at the Start and Application.Calculation = xlAutomatic at the end of code (Using Application.Calculate when needed in the code)
3. Rewriting the code to NOT copy. Copy and Paste takes up memory and slows things down. Try instead to write (as an example) Worksheet("Sheet2").Range("A2:C2") = Worksheet("Sheet1").Range("D5:F5").Value

One of the main reasons that Vba is slow is the time taken to access the worksheet from VBa is a relatively long time.
To speed up vba the easiest way is to minimise the number of accesses to the worksheet. What is interesting is that the time taken to access a single cell on the worksheet in vba is almost identical as the time taken to access a large range if it is done in one action.
So instead of writing a loop which loops down a range copying one row at a time which will take along time if you have got 50000 rows it is much quicker to load the 50000 lines into a variant array ( one worksheet access), then copy the lines to a variant array and then write the array back to the worksheet, ( one worksheet access for each search that you are doing),
I have a simple rule for fast VBA: NEVER ACCESS THE WORKSHEET IN A LOOP.
here is your code rewritten using a single variant array to all the input checks, this iwll make it a lot faster. (NOTE: untested )

Code: 
Sub CheckPS_noibang()
Worksheets("result").Range("A20:Z15000").Clear
Application.ScreenUpdating = False
Dim i As Integer, lastrow As Integer, lastrownoibang As Integer
   lastrownoibang = Sheets("noibang").Range("B" & Rows.Count).End(xlUp).Row + 1
   ' load the whole sheet inot a variant array
   With Sheets("noibang")
   
   inarr = Range(.Cells(1, 1), .Cells(lastrownoibang, 3))
   lastrow = Sheets("Result").Cells(Rows.Count, 2).End(xlUp).Row
    
    For i = 2 To lastrownoibang
            If (Left(inarr(i, 3), 1) = 5 Or Left(inarr(i, 3), 1) = 6 Or Left(inarr(i, 3), 2) = 47 Or Left(inarr(i, 3), 3) = 486 Or inarr(i, 3) = 20 Or inarr(i, 3) = 21 Or inarr(i, 3) = 22 Or inarr(i, 3) = 23 Or inarr(i, 3) = 24 Or inarr(i, 3) = 25 Or inarr(i, 3) = 26 Or inarr(i, 3) = 27 Or inarr(i, 3) = 28 Or inarr(i, 3) = 29 Or inarr(i, 3) = 30 Or inarr(i, 3) = 48) And (inarr(i, 4).Value - inarr(i, 5).Value) + (inarr(i, 6).Value - inarr(i, 7).Value) <> (inarr(i, 8).Value - inarr(i, 9).Value) Then
                     .Rows(i).Font.Color = vbRed
                     .Rows(i).Copy (Sheets("Result").Rows(lastrow + 1))
                     ' increment counter to avoid accessing workhseet again and again
                     lastrow = lastrow + 1
            ElseIf (Left(inarr(i, 3), 1) = 1 Or Left(inarr(i, 3), 1) = 2 Or Left(inarr(i, 3), 1) = 3 Or Left(inarr(i, 3), 1) = 8) And (inarr(i, 3) <> 12 And inarr(i, 3) <> 13 And inarr(i, 3) <> 14 And inarr(i, 3) <> 15 And inarr(i, 3) <> 16 And inarr(i, 3) <> 20 And inarr(i, 3) <> 21 And inarr(i, 3) <> 22 And inarr(i, 3) <> 23 And inarr(i, 3) <> 24 And inarr(i, 3) <> 25 And inarr(i, 3) <> 26 And inarr(i, 3) <> 27 And inarr(i, 3) <> 28 And inarr(i, 3) <> 29 And inarr(i, 3) <> 30 And Left(inarr(i, 3), 3) <> 149 And Left(inarr(i, 3), 3) <> 159 And Left(inarr(i, 3), 3) <> 169 And Left(inarr(i, 3), 3) <> 209 And Left(inarr(i, 3), 3) <> 219 And Left(inarr(i, 3), 3) <> 229 And Left(inarr(i, 3), 3) <> 239 And Left(inarr(i, 3), 3) <> 249 And Left(inarr(i, 3), 3) <> 259 And Left(inarr(i, 3), 3) <> 269 And Left(inarr(i, 3), 3) <> 279 And Left(inarr(i, 3), 3) <> 289 And Left(inarr(i, 3), 3) <> 299 And Left(inarr(i, 3), 3) <> 305) Then
