Consider you have a deck of 52 cards. Randomly select one (top one for this example). Now you only have 51 cards. Next select from these remaining cards (next one on top). and so on until there is only one card remaining. How would I write an excel formula to simulate this diminishing list selection?
Create a list containing two columns
column containing numbers 1-52
column2 containing RAND() function
Sort the list on column 2.

Hi there,
I want to be able to fill in data in the right hand table based off values entered in the log on the left.
So for example, column GL contains data from FR13, FR40, FR60, FR94 (every 27 rows), and rather than always type in '=FR' followed by the row number I'd like to drag down a formula to return the values.
I would also like to be able to drag the formula down the column
I have tried using ROWS and INDEX but it hasn't quite worked.
Many thanks for your help
Tried using ROWS and INDEX, expecting it to select the cells I wanted, but the pattern failed.
I am working on a report that displays monthly data most of which are represented in the following format, XX+YY (IE 01+11,02+10,03+09, etc.). The first set of digits reflect the represented month, so these naturally order themselves in sequence.

However, I must also include the financial plan for the year is in the format "FYXX Plan" where XX is the last two digits of the calendar year. When sorting text Power BI orders leading numbers before leading letters, so this moves the plan column to the END of the data set instead of where it logically belongs at the FRONT.
Image of visual with incorrect sequence
Is it possible to re-order my visual to still show the XX+YY monthly data in ascending order, but to move the FYXX Plan data to be the first column shown?
Very respectfully,
Jon J.
You could add a new column for sorting, stripping out the 'FY' when it exists e.g.
SortColumn = IFERROR(mid(Sorting[Date],find("FY",Sorting[Date])+2,10),Sorting[Date])
(For any value which includes 'FY' the mid function will show the remaining characters, if FY is not found it will error, and give the full date, there are a number of ways to achieve this using e.g. IF statements etc.
You can either replace the axis with this column, if you really need it to display as 'FYxx' you could set First(SortColumn) as the tooltip text to allow you to sort by that instead.
I'm trying to find a way to calculate the number of unique strings in a single column, excluding blank cells. So far I've seen solutions such as the following:
=SUM(1/COUNTIF(X2:X99;X2:X99))
Plus another similar formula using FREQUENCY instead of COUNTIF. However, applying this to my spreadsheet gives me a decimal value that has no apparent meaning. For example, if my column contains 20 cells containing "ABC", and 30 cells with "XYZ", I should have an output value of 2. However, this is not the case, and even I can clearly see that the above formula won't output anything larger than a 1, which has left me rather confused as to its usage.
Pivot tables seem to show the most promise, but I can't get that to work either. Here's what I tried:
Select the column, including the header
Select a new pivot table and use the selected range
Drag the header from Available Fields to Row Fields
Select the ignore empty rows option
Create the table
This then creates a table with one row per unique entry in the first column, and an empty second column. One row below is a Total Result cell, with the adjacent cell empty.
From this, I can see that there must be some sort of capability of the software to find unique strings, so it would stand to reason that there must also be a way of counting them and displaying that value in a cell. The question is, how do I do that?
Your first attempt should work if (a) wrapped in SUMPRODUCT and (b) the range does not contain blank cells:
=SUMPRODUCT(1/COUNTIF(X2:X51;X2:X51))
I have a DataPrep dataset which contains a series of ~10 columns, each of which indicates whether or not a particular brochure was selected:
BRO_AF BRO_SAF BRO_SE ...
1 1
1 1
1
I'd like to sum/count these values into a BrochuresSelected column.
I was hoping to use ADD with a column range (ie BRO_AF~BRO_ITA), but ADD only takes two numbers.
I can't use COUNT, as it counts rows not columns.
I can use NEST to create a column storing a map or array of brochures, but there doesn't seem to be a function for adding these. I can't use ARRAYLEN on this column, as even empty columns are represented in the column (eg ["1","","","","",""] would have an array length of six, not one).
Has anyone solved a similar issue?
If you know the column names, you can use the + operator in a derive transform. For example:
I want to calculate the medians for a series of numbers from an excel file.
My excel spreadsheet looks like this:
CELLNOUN 9.32
CELLNOUN 10.62
CELLNOUN 8.42
CELLNOUN 10.64
CELLNOUN 11.51
CELLNOUN 12.01
CELLNOUN 8.83
CELLSNOUN/CELLNOUN 9.53
CELLSNOUN/CELLNOUN 9.21
CELLNOUN/CELLSNOUN 10.76
CELLNOUN/CELLSNOUN 7.01
CELLSNOUN/CELLNOUN 10.21
PLANTNOUN/PLANTSNOUN 3.62
PLANTNOUN/PLANTSNOUN 3.38
PLANTSNOUN/PLANTNOUN 3.92
PLANTSNOUN/PLANTNOUN 3.24
PLANTNOUN/PLANTSNOUN 3.83
PLANTNOUN/PLANTSNOUN 3.24
PLANTSNOUN/PLANTNOUN 3.00
PLANTSNOUN/PLANTNOUN 1.80
...
In the spreadsheet, each set of words has been separated by a blank row, but the numbers of the entries for each set varies, like CELLNOUN/CELLSNOUN has 12 entries but PLANTNOUN/ has 8 entries. The numbers coming after the words are, in fact, the occurrences of these words. I want to find out the median of the occurrences for CELLNOUN/CELLSNOUN, PLANTNOUN/PLANTSNOUN etc, by using Regex instead of using the MEDIAN function in Excel to do it, because I have thousands of sets like this and I can't do it one by one on Excel. But if you know a quicker way to do it on Excel, please advice.
Thank you very much.
First of all, remove the blank rows from your data set and then create an Excel Table with Insert > Table or Ctrl-T. With an Excel table object, all functions and commands that refer to the table will catch when more data is added to the table.
Now you can create a pivot table from your source data with Insert > PivotTable. If you drag the first column field into the rows area, you will have a list of unique values in that source data column. You can drag the values column into the Values area of the Pivot Panel, if you want to. This should now look similar to this screenshot:
I'm not sure if you are aware of the different spellings of your categories, i.e. with or without an "S". The pivot table uncovers them all.
Out of the box, Excel PivotTables do not offer the Median as an option to aggregate, but you can use a method outlined here
http://www.myonlinetraininghub.com/calculating-median-in-pivottables
to calculate a median.
The exact approach varies depending on whether or not you use Pivot tables or Power Pivot, so check out the article.
Use an array formula as shown below and press ctrl+shift+enter to make it an array formula:
=MEDIAN((IF($A$1:$A$20=A1,$B$1:$B$20)))
Refer to the formula bar in the image below to apply to all cells by applying the same formula to all cells
