Refer to this simple Sales dataset

untitled

The objective is to create a simple matrix with months in the row labels, years in the column labels and sales figures in the value area section.  The twist in the question is that for years prior to the current year (2018 in this dataset), sales should only appear till the month for which there is data for the current year.  For e.g., for 2018, data is only till Month 4 and therefore for prior years as well, data should only appear till Month 4.  As and when Sales data gets added below row 17, data for prior years should also go up to that month.

The expected result is

Assume a three column dataset with Patient ID, Smoking Status and Review Date

PatientID SmokingStatus ReviewDate
P1 10-03-2018
P1 9 09-03-2018
P1 1 08-03-2018
P1 4 07-03-2018
P2 9 10-03-2018
P2 9 09-03-2018
P2 9 08-03-2018
P2 9 07-03-2018
P3 2 10-03-2018
P3 09-03-2018
P3 9 08-03-2018
P4 9 10-03-2018
P4 1 09-03-2018
P4 4 08-03-2018

The objective is the create another 3 column dataset with the following conditions:

  1. If the patient's latest smoking status is other than Blank or 9, then consider that as the smoking status of the patient; and
  2. If the patient's latest smoking status is blank or 9, then consider the previous smoking status that is not blank or 9; and
  3. If the patient's smoking status is blank or 9 on all dates, then consider the smoking status as 9

The expected result is:

PatientID Last date when the smoking status was other than 9 or Blank Smoking status on that date
P1 08-Mar-18 1
P2 10-Mar-18 9
P3 10-Mar-18 2
P4 09-Mar-18 1

I have solved this question using 3 methods - PowerPivot, Advanced Filters and formulas.  You may download my solution workbook from here.

Assume a five column database with the first column containing codes, second one containing a separator, third one containing some alpha values, fourth one is a combination of the first three columns and the last column has response times.

One may want to create as many charts as there are codes in column A.  The charts should get created on different sheets with the click of a button.

You may refer to my solution in this workbook.

Blanks appearing in source data not to appear in Data validation list

Assume a column of data with blanks appearing in a few random cells.  One may want to use this range of cells for creating a Validation drop down in a specified cell.  After creating the validation drop down, the blanks from the source data range would obviously show up in the drop down as well.

The task is to show only the entries in the validation drop down (without the blanks).  The question and instructions are very clearly mentioned in this workbook.

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 (no formulas at all) can solve this problem.  The result will be dynamic and refreshable (just as in a Pivot Table)

You may watch a short video of my solution here

Solution for all versions of MS Excel

While this solution works for all versions of MS Excel, it uses an array formula (Ctrl+Shift+Enter).  Array formulas, if used extensively in the workbook, adversely effect the system's performance.
