Delete rows of data based on ID from another workbook

[keiranwyllie]

Hi all,

Can anyone suggest the best to go about this please? I have one workbook that contains 1000's of rows of data. Each row has an ID in column A (This ID may exist on multiple rows). I want to use another workbook that only lists relevant ID, and have the original workbook delete all rows that do not contain any of those IDs (row 1 must remain). See below for example.

Workbook One (before any rows are deleted).

example.xlsx
	A	B	C	D	E
1	ID	Name	Title	Dept ID	Cse Name
2	100000	Doe, John	MR	102983	Course 1
3	100000	Doe, John	MR	102983	Course 2
4	100000	Doe, John	MR	102983	Course 3
5	100000	Doe, John	MR	102983	Course 4
6	100000	Doe, John	MR	102983	Course 5
7	100000	Doe, John	MR	102983	Course 6
8	110000	Doe, Jane	MS	102983	Course 1
9	110000	Doe, Jane	MS	102983	Course 2
10	110000	Doe, Jane	MS	102983	Course 3
11	110000	Doe, Jane	MS	102983	Course 4
12	110000	Doe, Jane	MS	102983	Course 5
13	110000	Doe, Jane	MS	102983	Course 6
14	120000	Jane, Mary	MRS	102983	Course 3
15	120000	Jane, Mary	MRS	102983	Course 4
16	120000	Jane, Mary	MRS	102983	Course 5
17	120000	Jane, Mary	MRS	102983	Course 6
18	130000	Lomar, Barry	MR	102983	Course 1
19	130000	Lomar, Barry	MR	102983	Course 2
20	130000	Lomar, Barry	MR	102983	Course 3
21	130000	Lomar, Barry	MR	102983	Course 4
22	130000	Lomar, Barry	MR	102983	Course 5
Sheet1

Workbook Two (contains ID of rows I want to keep)

Book1
	A	B	C
1	ID
2	110000
3	130000
4
Sheet1

Workbook One (expected data following deletion of rows)

example.xlsx
	A	B	C	D	E
1	ID	Name	Title	Dept ID	Cse Name
2	110000	Doe, Jane	MS	102983	Course 1
3	110000	Doe, Jane	MS	102983	Course 2
4	110000	Doe, Jane	MS	102983	Course 3
5	110000	Doe, Jane	MS	102983	Course 4
6	110000	Doe, Jane	MS	102983	Course 5
7	110000	Doe, Jane	MS	102983	Course 6
8	130000	Lomar, Barry	MR	102983	Course 1
9	130000	Lomar, Barry	MR	102983	Course 2
10	130000	Lomar, Barry	MR	102983	Course 3
11	130000	Lomar, Barry	MR	102983	Course 4
12	130000	Lomar, Barry	MR	102983	Course 5

Any help would be greatly appreciated.

Try this out.

Sub FilterArray()
    
    Dim wb As Workbook, bk As Workbook
    Dim sh As Worksheet, ws As Worksheet
    Dim MyArray() As Variant, x As Long

    Set wb = Workbooks("Source.xlsm")            'workbook with the code and the values to search for
    Set bk = Workbooks("example.xlsx")           'workbook to delete rows.
    Set ws = wb.Sheets("Sheet1")
    Set sh = bk.Sheets("Sheet1")

    With ws
        MyArray = .Range("A2:A" & .Cells(.Rows.Count, "A").End(xlUp).Row).Value
    End With

    With sh
        For x = .Cells(.Rows.Count, "A").End(xlUp).Row To 2 Step -1
            If Not IsNumeric(Application.Match(.Cells(x, 1), MyArray, 0)) Then
                .Cells(x, 1).EntireRow.Delete
            End If
        Next
    End With

End Sub

Thanks for the speedy reply. Unfortunately it's not working. I did a little debugging and noticed that it's trying to delete rows from workbook two (identified by deleting Not from the If statement). Trying to play around with the code now though to see if I can get it to delete from workbook one instead.

Try this out.

Sub FilterArray()
   
    Dim wb As Workbook, bk As Workbook
    Dim sh As Worksheet, ws As Worksheet
    Dim MyArray() As Variant, x As Long

    Set wb = Workbooks("Source.xlsm")            'workbook with the code and the values to search for
    Set bk = Workbooks("example.xlsx")           'workbook to delete rows.
    Set ws = wb.Sheets("Sheet1")
    Set sh = bk.Sheets("Sheet1")

    With ws
        MyArray = .Range("A2:A" & .Cells(.Rows.Count, "A").End(xlUp).Row).Value
    End With

    With sh
        For x = .Cells(.Rows.Count, "A").End(xlUp).Row To 2 Step -1
            If Not IsNumeric(Application.Match(.Cells(x, 1), MyArray, 0)) Then
                .Cells(x, 1).EntireRow.Delete
            End If
        Next
    End With

End Sub

Change the name of the workbooks in the code.
