Replace data with new data
 

I have a data file which I recieve regularly which needs to be cleane
up before I use it. The data looks like this

Item Description
123, Widget
124, Bodgit
125, Scarper
123, Unknown
124, Unknown
125, Unknown

Does anyone have a routine which could go through the above data an
make sure that the second field is corrected to what the descriptio
should be ?

I.e.

If first cell value equals 123, then make second cell value = widget
Or
If first cell value equals 124, then make second cell value = bodgit
Or
If first cell value equals 125, then make second cell value = scarper

The idea being that for every example of unclean data I come across,
would copy an extra line of code which deals with it in future edition
of the data file that comes in.

Hope someone can help ?

Thanks

Hi
one question: Are these to entries in two different columns? if yes you
don't need any code juyt add a helper column C and enter the formula
=IF(A1=123,"Widget",IF(A1=124,"Bodget",IF(A1=125," Scarper",""))
if you have more items you may consider using VLOOKUP for this. copy
this formula down as far as you need it

Thanks Frank

I have kind of used this approach already.

I was wanting to load the raw file, hit the ctrl-a button to run th
routine (or whatever button), then bish bosh, the file is cleaned u
and I can then dive straight in with creating my pivot tables and do m
normal thing.

Thanks again.

.... and also some of the data in the second column is ok and would need
to be left alone.

Hi Terry
though this can be done with a macro this wouldn't be faster as using
the formula :-)
But try the following (assumption column A stores the values)

Sub change_data()
Dim row_index As Long
Dim last_row As Long

last_row = ActiveSheet.Cells(Rows.Count, "A").End(xlUp).row
For row_index = 1 To last_row
Select Case Cells(row_index, "A").Value
Case 123
Cells(row_index, "B").Value = "Widget"
Case 124
Cells(row_index, "B").Value = "Bodget"
Case 125
Cells(row_index, "B").Value = "Scarper"
End Select
Next
End Sub


Note: will replace all values in column B (regardless if o.k. or not).
Assign this macro to a button or a shortcut

I wonder if I might ask a further question ? Can the code be writte
such that it refers to a named file which lists out all the items tha
need updating on the current spreadsheet.

I.e.

Start at current spreadsheet, line 1
Go to reference sheet and compare line 1 against the list in th
reference sheet and make changes as necessary.
Then go to line 2 and so on.... ?

Hi Terry
sure it can be done. Use the following code

-----
Sub change_data()
Dim target_wks As Worksheet
Dim lookup_wks As Worksheet
Dim lookup_rng As Range
Dim row_index As Long
Dim last_row As Long
Dim ret_lookup

Set target_wks = ActiveSheet
Set lookup_wks = Worksheets("lookup_sheet")
Set lookup_rng = lookup_wks.Range("A1:B30")

last_row = target_wks.Cells(Rows.Count, "A").End(xlUp).row
For row_index = 1 To last_row
With target_wks
If .Cells(row_index, "A").Value < "" Then
On Error Resume Next
ret_lookup = Application.WorksheetFunction.VLookup _
(.Cells(row_index, "A").Value, lookup_rng, 2, 0)
If Err.Number < 0 Then
ret_lookup = "N/A"
End If
On Error GoTo 0
.Cells(row_index, "B").Value = ret_lookup
End If
End With
Next
End Sub

-----

Assumption:
- the sheet with the references is called lookup_sheet (change this in
the code to your needs)
- the values are in columns A+B
