Cleaning Up Imported Data – A Recent Case Study

Yesterday in Formula Forensics 008 we looked at Elkhans MaxIf problem.

However the solution/formula as presented is the final solution to his problem.

Elkhans original worksheet contained other problems and today we will look at this:

I have attached the orginal file as a sample file you can Download Here.

You will see that the MaxIf cell F13 is returning 0, where it should be showing 0.246

 

Houston, We’ve Had a Problem!

Cell F13 has the same formula we looked at in yesterday’s Formula Forensics: =MAX(IF((Parameter_3=D13)*(Parameter_4=E13),Parameter_5,0))

A quick check of the formula reveals that everything was technically right with the formula, yet the answer is wrong?

To solve this I tried several steps which is the topic of this post:

Examine the logic of the If’s Criteria

The formula =MAX(IF((Parameter_3=D13)*(Parameter_4=E13),Parameter_5,0)) works by calculating the maximum value from the If array.

So step 1 was to look at the logic in the If’s Criteria

That is (Parameter_3=D13)*(Parameter_4=E13)

In cell F15 I entered = (Parameter_3=D13)*(Parameter_4=E13) followed by F9

Excel returns: = {0;0;0;0;0;0;0;0;0;0;0}

This tells me that none of the Cells match the criteria, strange?

Yet manually I can see 4 matching records, below:

Check Cell Length

The next quick step was to look at the length of the text in each cell.

In Column I, I added a =Len(E2) and copied down, there was only 2 characters in each cell, this step eliminated leading or trailing spaces.

Retype the Data

Elkham supplied the source data in an Excel file.

But the Criteria was manually typed by me.

 

So the next step was to retype some of the original data in Cell E2

Wow an Answer, So obviously there was a difference?

 

What is Wrong Here?

So obviously there was a difference between the C1 in cell E2 and the C1 in cell E13?

I checked this in 3 ways

1. Type the value “C1” into Cell E2, without the quotes

This returned an answer 0.08 from F2 as it should have.

2. Copy an old “C1” value to E13

This resulted in the correct answer of 0.246 in F13

 

3. Use a quick Formula

Entering a quick formula

In F17 type =E2=E13

Excel returns False

Showing that the value of cell E2 does not match E13

 

So what is in E2:E12 ?

As I had typed the values into the Criteria Cells D13:E13, I knew what they were, they were a plain and simple “C1”

So what was in E2:E12 ?

Next step was to look at the Ascii values of the 2 characters in Column E.

In K2: =Code(Left(E2,1))

In L2: =Code(Right(E2,1))

Copy both down to Row 13

Bingo !

The Character C in cell E2 wasn’t the same as the Character C in E13 ?

Yet both cells contained a Calibri Font.

If I now type in a spare cells:

F18 =Char(63), Excel displays a “?

F19 =Char(67), Excel displays a “C

Yet Cell E2 is clearly displaying C1 with a First Character Ascii code of 63 which should be a ? mark.

I suspected that it had been copied and pasted from MS Access, So I shot an email back to Elkhan, asking “What the source of the data was?”.

The response came back that “The data had been copied from a Russian (Cyrillic) version of an MS Word File and pasted into an English version of Excel.

I can’t explain what has happened but somehow the character sets and associated values got scrambled when copied the data from the Russian Word Document into Excel

If you have had experiences like this or can explain what has happened please do so in  the comments below:

 

Solution

The Solution was now easy

Use Search/Replace

Copy the contents of cell E1,

goto Search/Replace or Ctrl H

Find: Paste the contents of Cell E1

Replace with: C1

 

Conclusions:

  1. Be careful when receiving data from foreign language files, including word and Excel files
  2. Check summations based on such data to ensure its integrity
  3. Be methodical in tracking down problem cells

    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 [...]

  6. Jon Gali says:

    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."

  11. Letitgo says:

    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??

  13. Tushar says:

    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

    TIA
