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

    We have only just got excel 2007 so this is helping me navigate my way through the differences cheers.

    For Macro's i always add a Command Button, rename it something obvious, change the colour of it and finally add the following to its View Code section.

    Application.Run "MAcro1"

    This way anyone opening the file knows what to do if i ever win the lottery and dont make it in 🙂

  2. Ron Murphy says:

    Hi,
    Good article. But I have this problem.
    1) Customized QAT with a macro. Macro name = MacroX
    2) Runs OK from original location (e.g. C:\TestLoaction1\TestFile.xls)
    3) Copy past file to new location (e.g. C:\TestLoaction2\TestFile.xls)
    Menu button now fails:
    Cannot run the macro "C:\TestLoaction1\TestFile.xls'!MacroX' The macro may not be available in this workbook...

    Of course the code is there, and macros are enabled.

    Could get it to work after deleting and recreating macro custom buttons. So have to re-assign macro to QAT button every time I move the file?

    If I put a form button on he worksheet and assign the macro to that, it's location independent.

    Any ideas?
    Thanks

  3. Hui... says:

    @Ron
    What you have said is correct
    Macros within a worksheet are stored within the worksheet and hence follow it.
    Macros referenced by a button in the QAT or elsewhere are locaed in a file and if that file is moved the linkages don't follow.

    The easiest way around this is to store all your macros in a location that doesn't move and is in fact reloaded everytime that Excel starts and that is called the Personal.xlsx/b file.

    These are refered to several time at Chandoo.org or have a read of
    http://www.rondebruin.nl/personal.htm
    or

    • Col Delane says:

      In Excel 2003 and prior versions, a button added to the Toolbar maintained a DYNAMIC link to the file (e.g. Personal.xlsb) holding the assigned macro, such that if the file was relocated for any reason (by using Excel's native Save As command rather than just moving it via Windows Explorer), the link between the button and the file was updated.
      I expected the same to occur with Excel 2007+, but alas, Microsoft in their infinite wisdom have removed another feature useful to advanced users (just as they did by removing the ability to design your own buttons)!!
      So having just done some reorganisation of my files, I now have to remove and recreate every friggin macro button on my QAT (I have lots) - what a pain in the proverbial!!

  4. Ron Murphy says:

    Hi Hui,

    Thanks for the help, that's really useful.

    1) The macros I'm adding are for one specific Excel application, so I really wanted the macros to follow the file

    2) I didn't want to have to pass other files around too and have users installing those - either Personal.xlsx/b or as an Add-In.

    3) I realise now that the QAT additions will appear for other Excel workbooks in which I don't want the macros available.

    So, it looks like I need to keep it local, by using a button on the worksheet. Unless you can suggest any way of adding to menus just for a specific workbook.

    Thanks again for your help. Great site, so I'll be signing up for the emails.

    Ron

  5. cheryl says:

    I know I'm a little late jumping on this post, but wondering if anyone knows how to add a UDF to the QAT? I've saved my UDF in my personal workbook, but it does not show up in my list when I choose Macros when customizing my QAT. Suggestions? Thanks!!

    • Chandoo says:

      @Cheryl: UDFs cannot be accessed like Macros. You can use them from other macros or from worksheet cells as formulas...
      @David: If you save your macros file and then install it as an add-in then it will be always available for you.

  6. David says:

    The instructions work great when you are creating a new file, and it is still open. I find that I can't access macros after I've saved a file as an xlam and closed it. When I reopen the xlam, either by browsing to it, or by having it set to open as an addin using Excel Options, the macros are no longer available in the macros list when I go to edit the QAT. Any way around that?

  7. JimH says:

    I need to create a button that will run a macro. Once you click the button it needs to open up a browser asking you to select a report/file. Once you select the file, it will run the macro on the selected file and then save it as a new report with a name and the current date. I created the macro to sort/modify the report but I do not know how to do what I mentioned above. I hope this makes sense.

  8. NathanG says:

    I'm having trouble adding a macro to the QAT. I've done everything up to step 5 but my macro isn't showing up. What am I doing wrong?

  9. surfinette says:

    Hi,
    Thank you for the explanation. Very useful for a recent switcher from office 2003 to office 2010.
    My follow-up question is: in Excel (or ppt) 2010, can you customize the macro button that you put in the QAT?
    In office 2003, once you chose the custom button for your Macro, you could then edit pixel by pixel the said button.
    For instance, I've created 2 Macros in PPT that are converting all my slides to either English or French language, so I'd like one button to show EN and the other FR... that would be more meaningful that any of the possible "custom" office 2010 buttons

  10. Morton Wakeland says:

    I read all the post and one important aspect to the QAT was never mentioned. That is, you have a macro driven worksheet that you want to share with other. You have customized the QAT with two icons to run the macros (VBA programs in reality). However, when the others receive the workbook, the icons are no where to be found. It's my understanding those "customized buttons" have been saved to an outside file, Excel.qat. QUESTION: Could one simply attach that file to your email, along with the worksheet, and tell the recipients to copy that file to correct location on their computer - C:\Users\\AppData\Local\Microsoft\Office|\
    Would the customize macro buttons then appear in the worksheet and, more importantly, work? Thanks for your thoughtfulness and thanks for well written instructions Chandoo!
