Excel: Copy and insert rows on another sheet based on cell - vba

Question

I'm trying to make a code that checks for numbers in a master sheet called All in column D (ex. 780101) and if it meets the criteria, it copies the whole row and inserts (not paste) it to another sheet with the name of the criteria (ex. 780101), starting on row 6.
The code I have doesn't work like I want it to. It doesn't copy all the rows that meet the criteria and sometimes it inserts blank rows.
Sub Insert()
For Each Cell In Sheets("All").Range("D:D")
If Cell.Value = "780101" Then
matchRow = Cell.Row
Rows(matchRow & ":" & matchRow + 1).Select
Selection.Copy
Sheets("780101").Select
Rows("6:6").Select
Selection.Insert Shift:=xlDown
End If
Next
End Sub
I'm just starting to learn VBA, so if it could be possible the names of the sheets would be the criteria of the cell values (the code is made for only one sheet - 780101, but there are 20 of sheets with different names).

Answer 1

It's tough to make recommendations without seeing sample data and what could potentially be causing the problems you are having but you can run this rehash of your existing code.
Sub Insert()
Dim dc As Range
With Sheets("All")
For Each dc In Intersect(.Range("D:D"), .UsedRange)
If dc.Value2 = 780101 Then
dc.Resize(2, 1).EntireRow.Copy
Sheets("780101").Rows(6).Insert Shift:=xlDown
End If
Next
End With
End Sub
The nature of running that from top to bottom means that the results will be reversed. You may wish to consider running the main loop from bottom to top to maintain the order.
