Determine number of learners who have completed different stages of multiple online courses

{4 Comments}

Here is a sample dataset of learners who have cleared different stages of multiple courses on offer within an Organisation:

Learner Stage completed Course
Bill Stage 1 Public Speaking
Bill Stage 2 Public Speaking
Bill Stage 3 Public Speaking
Susan Stage 1 Effective Communication
Bob Stage 1 Public Speaking
Bob Stage 2 Public Speaking
Sheila Stage 1 Effective Communication
Sheila Stage 2 Effective Communication
Sheila Stage 3 Effective Communication
Frank Stage 1 Effective Communication
Frank Stage 2 Effective Communication
Henry Stage 1 Public Speaking
Henry Stage 2 Public Speaking
Bill Stage 1 Effective Communication
Bill Stage 2 Effective Communication

From this sample dataset, one may want to know how many participants have completed each stage of these multiple courses.  The expected result is shown below:

Row Labels Stage 1 Stage 2 Stage 3
Effective Communication 1 2 1
Public Speaking 2 1
Grand Total 1 3 2

In this workbook, I have shared 2 solutions - one using formulas and the other using the Power Query & PowerPivot.

Create a Pivot Table from multiple individual ranges without using ancillary columns

{16 Comments}

Assume that there are three separate tables showing the following information:

1. Date of visit data for visitors to a certain recreation facility.  The same visitor may visit the facility multiple times
2. Fee per visit in different cites
3. Region in which each city lies

The question is to analyse the three tables above via a Pivot Table to generate the following:

1. Region wise and visitor wise:
a.  Fee per visit
b.  Frequency of visit
c.  Revenue
2. Revenue collected by month wise and by visitor

In this workbook, I have shared two solutions:

1. PowerPivot solution - This solution answers both questions above without using any calculated/ancillary columns in the base data.  By establishing simple relationships in the PowerPivot window and by writing two calculated Field formulas, both questions above have been answered.  To use this PowerPivot solution, you need to be using the PowerPivot add-in for MS Excel.  This add-in is only available for Excel 2010 and higher versions.

2. Pivot Table solution - This solution answers both questions above by using calculated/ancillary columns in the base data.

Here's another example.  Assume a four column table showing Date of session, Client, Location and Participant Name.  Assume another four column table showing Client, Date of session, Date of invoice and Amount Billed.  The task is to determine the Amount billed per location.  You may refer to my PowerPivot and Pivot Table solution in this workbook.

Show granular as well as total figures on the Summary sheet

{0 Comments}

Assume there is data for complaints received and complaints resolved for two years - 2009 and 2010 for some regions regions.  Each Region has its own worksheet.  There are three headings on each sheet - Particulars, 2009 and 2010.  While the Particulars column has the text "Complaints received" and "Complaints resolved", the year columns have number of complaints received and resolved.

The task is to create a Summary sheet which:

1. Show the consolidated figure of complaints received and complaints resolved for both years
2. Show the individual regions which make up the consolidated figure in 1 above.

In this workbook, you may see the data layout and four different ways of resolving the two tasks mentioned above.

Generate a list of missing invoice numbers

{2 Comments}

In a range of cells, assume there is a list of invoices raised during a certain period.  Since adequate care was not taken to number the invoices sequentially, there are missing invoice numbers in the Excel range.  So, it is possible that after raising invoice number 501, 502 and 503 the next invoice raised was 507.

Given the following:

1. Starting and ending invoice number (two numbers) from the invoice book; and
2. List of actual invoice numbers raised during a certain period (as elaborated above)

one may want to generate a list of missing invoices.

You may refer to two solutions in this workbook.

Sum data from a particular cell of last n sheets only

{0 Comments}

A number is entered in cell A1 of every sheet in a multi sheet workbook.  The task is to sum numbers in cell C2 of the Summary sheet from cell A1 of last x sheets - x is the number of sheets (mentioned in cell B2 of the Summary sheet) from which numbers have to be summed up.  So if the number entered in cell B2 of sheet is 3, then sum numbers from cell A1 of last three sheets.  Worksheets can get added, removed or renamed.

You may refer to my solution in this workbook.

Count text values in a range

{0 Comments}

In range C4:C10, assume the following values/formulas

1. Cell C4 - 1
2. Cell C5 - 2
3. Cell C6 - W
4. Cell C7 - We
5. Cell C8 - Empty cell
6. Cell C9 =IF(D9+E9=2,"a","").  Please ensure that cells D9:E9 are empty
7. Cell C10 =1/0.  This will yield the #DIV/0! error

To count numbers and text values in the range above, you may refer to my solution in this workbook.

Display text entries in the data area of a pivot table

{60 Comments}

Assume a two column database of approximately 20,000 rows (say from A1:B20237).  The first column has vendor names and the second column has Part codes (alphanumeric string).  Headings are in A1:B1, say Vendor in cell A1 and Part_code in cell B1.  One vendor supplies multiple parts and therefore there would be repetitions of vendor names in column A.

The task is to reorient this database to show all part numbers in column A and parts supplied by those vendors should appear in different columns of that row.  If one attempts to create a pivot table, the problem would be with the data area of the pivot table.  When one drags the part codes (alphanumeric string) column to the data area, count of part number would appear instead of the actual part number.  This is the very nature of a pivot table.  Since it is a summarisation tool, one can never see text entries in the data area of a pivot table.

You may download the workbook showing both solutions (using MS Query and Power Query) from here.

Depending upon the version of MS Excel which you are using, there could be two ways to solve this problem

Solution for MS Excel 2010 and higher versions

If you are using the Power Query add-in, then a few simple steps (minimal formulas) can solve this problem.  The result will be dynamic and refreshable (just as in a Pivot Table).  You may refer to Solution2 - Power Query worksheet.

You may watch a short video of my solution here

Solution for all versions of MS Excel

You may refer to Solution1 - MS Query worksheet.  To reorient the data i.e. to view text entries in the data area of a pivot table, try the following approach:

1. In cell C1, type Count.  So the value in cell A1 is Vendor, in cell B1 is Part_code and in cell C1 is Count
2. In cell C2, enter =$B$1&" "&COUNTIF(A$2:A2,A2) and copy down.  Since the number of rows here are quite many, i would suggest copying in batches i.e. first copy down 5,000 rows, then another 5,000 rows and so on.  This is solely to prevent Excel from crashing and/or taking unduly long to process.
3. Select range A1:C20237 and press Ctrl+F3 > New.  In the name box, enter Dummy
4. Select range A1:C20237 and press Ctrl+T to convert to a Table.  This is to take care of data being added beyond row 20237.
5. Save the file and open a new worksheet (in the same workbook)
6. While on any cell in this new worksheet, go to Data > From Other Sources > From Microsoft Query > Excel Files > OK
7. Navigate to the folder where you saved the file in step 5 above, select the file and click on OK
8. With Dummy selected by default, press the > symbol.  This will show you three column headings in the right hand side box
9. Click on Next three times
10. Select the second option button and click on Finish
11. Click on the SQL button and delete all contents that you see there.  Type the following in the blank white space

TRANSFORM first(Part_code)
SELECT Vendor
FROM dummy
GROUP BY Vendor
PIVOT count

12. Click on OK
13. Go to Data > Return Data to MS Excel
14. In the Import Data box, select Table and in Existing sheet, select cell A1
15. Click on Finish

Data should now appear in the desired format.

For any changes to data in range A2:B20237, right-click on any cell in the output range and select Refresh.  Furthermore, since the range has been converted to a Table, you may even add further rows of data and simply right-click to Refresh the output data range.

To improve performance of your workbook, you may want to copy the formulas in column C and paste them as Values (Paste Special > Values).  Once again, do not paste special all values at once - do so in groups of 5,000 rows to prevent Excel from crashing and/or taking unduly long to process.

Calculate turn around time excluding Sundays and public holidays

{188 Comments}

Assume a two column database showing starting date/time and ending data/time (Data/time stamp appear in a single cell).  Given a list of public holidays in a year and starting and ending work times, one may want to know the turn around time excluding Sundays and public holidays.

You may refer to my solution in this workbook.

Extract n th. most frequently occurring item from a database

{2 Comments}

Assume a database in range D5:D11 with the following values - Black, Black, Purple, Purple, Grey, Grey, Grey.  To extract the most frequently occurring item, one may use the following formula

=INDEX($D$5:$D$11,MODE(MATCH($D$5:$D$11,$D$5:$D$11,0)))

To extract the second most frequently occurring item, try the following:

1. Enter 2 in cell C16:
2. In cell D16, enter the following array formula (Ctrl+Shift+Enter)

=LOOKUP(2,1/(LARGE(FREQUENCY(IF(INDEX(COUNTIF($D$5:$D$10,$D$5:$D$10),0),MATCH($D$5:$D$10,$D$5:$D$10,0)),ROW($D$5:$D$10)-ROW($D$4))+(ROW($D$5:$D$11)/10000),C16)=FREQUENCY(IF(INDEX(COUNTIF($D$5:$D$10,$D$5:$D$10),0),MATCH($D$5:$D$10,$D$5:$D$10,0)),ROW($D$5:$D$10)-ROW($D$4))+(ROW($D$5:$D$11)/10000)),$D$5:$D$10)

To extract the n th most frequently occurring item, enter that n th number in cell C16.

Summarise data from multiple sheets with one condition – PartII

{2 Comments}

Assume a worksheet which has scores (1-10) on four future dates on nine questions.  Each row represents responses for one question.  Likewise there are 20 respondents i.e. 20 worksheets which have the same structure.

One may want to summarise data from all 20 worksheets into one worksheet.  The question and solution are more clearly explained in the attached file.

I have presented two cases here - Example 1 and Example 2 in this workbook.
