Hello,
Can you please help.
I have hundreds of postal codes (Sheet1),  
I need to look up the zones (Sheet2), then look up the prices (Sheet3).

I wonder if there is a macro that can do this.

Sample attached.

Any help is appreciated.
Thank you

Is there any possibility of having the Postal Codes listed separately in the Zones sheet? For example, instead of listing B0A-B0C on one row, use 3 rows...

B0A    Y
B0B    Y
B0C    Y

And also only use 2 columns, with all PCs in column A and the zones in column B.

If that is possible, you could then use a simple VLOOKUP to return the zone....

    =VLOOKUP(A3, Zone!A:B, 2, FALSE)

Then to find the Envelope and Pack, you could use HLOOKUP....

    Envelope  =HLOOKUP(B3, Price!$4:$7, 3, FALSE)
    Pack  =HLOOKUP(B3, Price!$4:$7, 4, FALSE)

And given that the price for the different weights increases by $2.00 for each lb, you could use these formulas for the different weights...

    5lbs  =G3+2*5
    10lbs  =G3+2*10
    25lbs  =G3+2*25
    50lbs  =G3+2*50

...where cell G3 is the Pack price.

There could be a macro that would do this, but it would be far easier if you got a fully enumerated list of postcodes per zone rather than ranges of postcodes (e.g. A0A-A9Z). Maybe the macro you are looking for is one to convert that 'zones' listing to a two column listing of all individual postcodes within each range?

Without macros, I think I've done what you needed, simply by converting the zones to a single two column table and using a vlookup against it with the 'range_lookup' argument set to true. That gets the zone (provided that the zones listing is sorted alphabetically) and I then get the price by using the MATCH and INDIRECT functions to get the appropriate value from the prices table.

Please see attached.Postcode-Price-Lookup.xls

I wouldn't bet my job on all the answers being correct without checking the results carefully. The range lookup version of VLOOKUP provides the nearest match without overshooting in the sorted data, so if you're looking for 'BA' and the values in the sorted lookup range go from
'AA'
to
'CA'
it will return the lookup value from the 'AA' row, which may not be appropriate in your situation. Far, far better to get a fully enumerated list of postcodes per zone and do the vlookup on exact matches only.

It looks like you have quite a few responses already, but since I've worked on it, I'll share what I've done.

I assumed that the Postal codes can be enumerated as Base 36 numbers.  this way, I was able to determine if a Postal Code falls within the range.

Excel Sample Attached

Code:
Public Function getZone(txtPostalCodeSearch As String)

Dim ArrPC
Dim txtPostalCodeLookup
Dim iRow
Dim txtZone
txtZone = "Unknown"

Dim rng As Range, cell As Range

Set rng = Range("ZoneLookup!A2:A223")

iRow = 1
For Each cell In rng
 iRow = iRow + 1
 txtPostalCodeLookup = cell.Value

' Get the postal code or codes into an array
ArrPC = Split(txtPostalCodeLookup, "-")

Debug.Print UBound(ArrPC)

If UBound(ArrPC) = 0 Then
 If txtPostalCodeSearch = ArrPC(0) Then
   txtZone = Range("ZoneLookup!B" & iRow).Value
 End If
 Else
If SearchPostalRange(txtPostalCodeSearch, ArrPC(0), ArrPC(1)) Then
    txtZone = Range("ZoneLookup!B" & iRow).Value
 End If
  
End If

Next cell

getZone = txtZone

End Function



Public Function SearchPostalRange(txtSearch, txtStartRange, txtEndRange)

Dim dblSearch
Dim dblStartRange
Dim dblEndRange

dblSearch = BaseToDec(txtSearch, 36)
dblStartRange = BaseToDec(txtStartRange, 36)
dblEndRange = BaseToDec(txtEndRange, 36)

If dblSearch >= dblStartRange And dblSearch <= dblEndRange Then
  SearchPostalRange = True
Else
  SearchPostalRange = False
End If


End Function



Public Function BaseToDec(ByVal strBaseNumber As String, ByVal intBase As Integer) As Double

Dim i As Integer
Dim strDigits As String
Dim strDigitValue As Long

strDigits = Left("0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ", intBase)

For i = 1 To Len(strBaseNumber)
strDigitValue = InStr(1, strDigits, Mid$(strBaseNumber, i, 1), vbTextCompare) - 1
If strDigitValue < 0 Then Err.Raise 5
BaseToDec = BaseToDec * intBase + strDigitValue
Next

End Function

Thank you all.

Jeff,
Excellent, this seems to be working.

2 questions,
1- is there a way to run it as a sub, I want to create a button to run it when I edit the codes.
2- how did you get the postal codes to go into 2 columns? did you run a macro?

thank you very much.

I manually edited the Postal codes sheet so that the codes were only in one column.  The ranges of codes are still there exactly as they were before, just on one column.

Do the codes always come in multiple columns?  Is it always the same number of columns? I could write a sub to convert those  columns to one, but it seemed like a trivial thing to do as a one time manual edit.

After double checking my work, I found that Cell D8 needed correcting.   revision attached
