Clean up Incorrectly Formatted Phone Numbers using Excel

cleanup-phone-numbers-using-excel-howtoIn our Utopian imaginations all the data would have been standardized and shareable across systems and people. But alas, the reality is totally different. We seldom get data in the format / way we desire it to be. In other words, the ingredients are all there, but for us to prepare the dinner, you must pre-process them.

Often this pre-processing or cleaning up the data takes quite an amount of time it self leaving very little to do the actual work. That is when you can use excel’s powerful data cleaning techniques to handle the situations.

One common problem with corporate data is incorrectly formatted phone numbers. Most of us are used to a standard 10 digit phone number format like 123-123-1234 or (123) 123 1234, but when you get that customer data, very few phone numbers in it are formatted like above. Instead you might see phone numbers like 1231231234, 12312 31234, (123)123-1234 etc.

It is not really difficult to clean up the phone numbers if we know before hand how they are formatted. For eg. you can easily convert a phone number like 1231231234 to 123-123-1234 using excel text formatting functions like =TEXT(1231231234,"000-000-0000"). But it is a rare case in which we have control over the incoming format and quickly you will have to use a slew of format / text processing functions to clean up the data.

To simplify the whole thing, I have written a small VBA UDF (User Defined Function) which you can add to your excel add-ins list and use to clean up virtually any phone number format to standard phone number.

Function cleanPhoneNumber(thisNumber As String) As String
    ' this function aspires to clean any phone number format
    ' to standard format (+9999) 999-999-9999 or 999-999-9999
    ' works with almost all phone number formats stored in text

Dim retNumber As String

For i = 1 To Len(thisNumber)
    If Asc(Mid(thisNumber, i, 1)) >= Asc("0") And Asc(Mid(thisNumber, i, 1)) <= Asc("9") Then
        retNumber = retNumber + Mid(thisNumber, i, 1)
    End If
Next
If Len(retNumber) > 10 Then
    ' format for country code as well
    cleanPhoneNumber = Format(retNumber, "(+#) 000-000-0000")
Else
    cleanPhoneNumber = Format(retNumber, "000-000-0000")
End If
End Function

The above function is pretty straight forward and simple. It scans the input text for any numeric ASCII codes and saves them to another text field. Once the scanning is complete the function will format the final number to 999-999-9999 format if the number has 10 or less digits, otherwise to (+9999) 999-999-9999 format (with country code).

    Its possible to display up to 4 text values.

    Have a look at the screen shot of an example that I had posted way back at the EHA and figure out how its done !

    With Excel 2010 you can use Conditional Formatting to apply custom number formats which can display text. (In older versions you can only modify text color and cell background color, but not number formats.) Using CF allows for an even larger number of different display values.

    Hey,
    Thanks, this helps. But how do you do it for multiple values where there is a huge amount of non repeating  text? 

  4. [...] Pivot Tables take tables of data and allow the user to summarise and consolidate the data at the same time. This is a great and very fast method of analysis but is restricted to handling mathematical functions on the value field resulting in numerical summaries. – read more [...]

    There is a very good way actually for handling text inside values area.
    First you create a special column on the very left side and call it ID, and put unique ID (numbers only), and then create a pivot table with:

    Row Labels and Column labels as you like, and in the Values labels use the unique ID number.

    Move the unique ID number (copy paste) somewhere to the right and use vlookup to load the data you need using the ID as reference.

    It is a bit longer way but for me it works perfectly to combine values as you like in any moment.

    hope helps.

    Regards,

    Jon

    Good Day. This is exactly what i have been looking for. However when i try it on my pivot table or even when i try to recreate this exercise using the sample worksheet, i get this error:

    "Microsoft Excel cannot use the number format you typed. Try using one of the built-in number formats."

    I found an easy way to get text values in pivot table.

    I create an other worksheet in wich each cell has a formula that copy the pivot table. The trick is that the formula does a lookup for the numbers in the pivot table.

    The formula looks like that:
    =IF(ISNUMBER(table!A1);VLOOKUP(table!A1;Code!$A$1:$B$65;2);IF(ISBLANK(table!A1);" ";table!A1))

    Code is a worksheet where there is a liste of text /numbers correspondance.

    As a bonus The new sheet is easier to format

    Additional trick:
    In my case, i encoded differents codeid with a power(2, codeId-1) so that summing then is equivalent to concatenate them.

    1-A
    2-B
    4-C
    8-D

    yields :

    5 - AC
    14 - BCD

    Hi
    I want to ask if pivot can display dates in pivot field. As in a column i have customers and in row different items i want to know there last purchase date. anyone help in this??

    Hello Guys, Need your help
    I am doing some analysis of the cycle time of the product i.e how much time a product takes from manufacturing to the central warehouse.
    I have batch numbers for the product and against them i have to pull out the diff. dates
    Like the base date is from where the manufacturing start. So i have the batch number,against it's manuf. date. Now i have to pull out the date when it was quality released.
    I have the quality released data but the data have duplicates, like i will have two dates or may be three for the same batch. So my main objective is to pull out the date which is latest among them.

    BATCH NO. DATE of Mfg. DATE of Quality release
    A1 12/4/2014 (HERE I HAVE TO PULL value)

    Next Sheet
    BATCH NO. DATE of Quality Release
    A1 14/5/2014
    a2 23/5/2016
    A1 12/5/2014
    A1 13/6/2014

    From this sheet i have to pull up the latest date format of date here is dd/mm/yyy
