  1. You are great and as a student of data analysis,I just joined your column by accident and i am enjoying every bit of information you have published in this field.
    However, I want to know the real difference between using SUMIFS, COUNTIFS, and AVERAGEIFS to summarize data using multi-criteria and the INDEX+ MATCH COMBINATION.
    Thanks.

  2. hi dear,
    i have one issue kindly help me
    i have 2 row
    suppose that
    10 20 30 40 50 60 70 80 90
    15 25 35 45 55 65 75 85 95
    greater than formula???
    if i put the value in cell (30) and i wanna search the greater value in 2nd row.Which formula i put in cell than show the answer is (35)
    because 1st row 30 is greater than 2nd row 35.

  3. i have a table.
    coloumn names( employee name, basic salary, allowance, netsalary)
    row names(employee 01, employee 02,.......,employee 10)

    i want to extract the employee whose basic salary is grater than $200.

    how to do it?
    i don't like use a filter method.

  4. Need your kind help.
    I linked a master sheet (some range of cells) with many other sheets (with the same cell reference range) using arrays. However, some functions are not working in the Master sheet. For eg. sum function does not work out within the cell ranges which are linked. Any ideas????

  5. thanks you all, for puting someone into light

  6. I have a list of potential % changes in a variable and another list with the probability that % change will occur. If I use the Data Analysis Random Number Generator it does not allow the number to be recalculated and accept changes in the simulation. How do I generate a non-static random % change based on the assigned probabilities?

  7. Hi, need help comparing text (separated by commas) in 2 cells, to see what is different. For example:

    A1 = John, Matt, Shelly
    A2 = Polly, Shelly

    We can see that John and Matt have been removed from A2, however Polly has been added. What is the best way to go about pinpointing the differences between two cells?

    but this does not works. can you help? thanks

    1. Hi Joao Barros,

      You should use the following array formula:
      {=IF(SUM(IF(TEXT($B$1:$B$10,"yyyy-mm-dd")=TEXT(A1,"yyyy-mm-dd"), 1, 0)), "D", "xxx")}
      Where the array AK is in B1:B10 and the array P is in A1:A10.

  12. HI,
    MY QUESTION IS ,I CREATE A1 TO A12 MULTIPLE IN RESULT OF B1 TO B12 IN ALL CELL FROM MULTIPLE VALUE OF *3. PLEASE PROVIDE INFORMATION.
    THANKS

  13. I have a list of (+) and (-) in a column, each one needs to be assigned a number based on it's position to the last of it's kind on the list. So the list may have 2 (-) then 3 (+) then another 2 (-). I'd like to run a formula that will assign an odd number to the (-) and an even number to (+) but consecutively. So the first two would be 1,3, the next three would be 2,4,6, then the next two would be 5,7. I've tried setting to columns with the numbers and using an array formula({=if(A1:A8="(-),C1:C8,D1:D8)}, assuming C column has 1,3,5,7,9,11,13 and the D column has 2,4,6,8,10,12,14 listed) the problem I've come across is that it takes it consecutively for the last number so it would go 1,3,6,8,10,11,13 instead of the desired 1,3,2,4,6,5,7. Any ideas how to fix this?

    1. Hi Krista,

      If I understand you correctly you should use the following array formula:

      {=IF(A1="-",SUM(IF($A$1:$A$7="-",1*IF(ROW($A$1:$A$7)<=ROW(A1),1,0),0)) *2 - 1, SUM(IF($A$1:$A$7="+",1*IF(ROW($A$1:$A$7)<=ROW(A1),1,0),0)) *2)}

      Where the values "+" and "-" are in A1:A7.

  14. 2 kg + 3 kg = 5 kg.

    I want the kg should come once the calculation is completed as above eg. shows

  15. Hi,

    Please could you help with a formula.

    I am trying to work out a moving average for the following:

    Week Commencing Number Value
    20/07/2015 7 £2,000.00
    27/07/2015 37 £5,000.00
    03/08/2015 73 £397,270.97
    10/08/2015 40 £238,580.87

    So for example week 20/07/2015 I'm using the formula =sum(d2/c2). I want a continuous formula that adds the weekly numbers as each week passes so for the second week the sum would be 7+37 =44 and the value would be £2,000 + 5,000 = 7,000 so £7,000/44.

    I require the formula to be continuous as I have many weeks to work out the average.

    Thanks for your help

  16. Hi,

    If the cell A1 is more the 45 to add 15 and if A1 is less than 45 to times/multiply by 1.2

    Please if anyone could kindly help which formula i would have to use

    Many Thanks,

    Abe

    1. Hi Abe,

      If my understanding of the task is right, you can use the following simple formula:

      =IF(A1>45, A1+15, A1*1.2)

  17. Can you please explain to me what causes the following inconsistency with a non-array formula?

    =LARGE(IFERROR({4,5},0),1) returns 4

    BUT when evaluating the IFERROR part using F9 the formula returns:

    =LARGE(IFERROR({4,5},0),1)
    [F9] =LARGE({4,5},1)
    [enter] = 5

    Please do not reply that the solution is to enter the formula using Ctrl+Shift+Enter, my problem is more subtle: why does Excel give a different result when the formula is evaluated in 2 steps?

  18. Thanks a lot for this nice article which explains a lot.

  19. Hi,
    I've extracted data specific to employee names from a master sheet using array formula.

    I'm struggling to create a dynamic chart to display this data using excel.

    Any tips on how this can be done?

  20. Is it possible to define an array that is a combination of cell ranges and constants? For example how would one use a a three element array made up of {A2, 2-A2, 1} in a formula where A2 is a cell reference? Seems like it should be easy, but I'm stumped. Thanks!

    1. I have entered this formula and got the correct result:
      {=SUM(A1,2-A2, 1)}

  21. I have an Excel dataset consisting of 500 rows by 7 columns. I am generating additional data points from this dataset. I need to multiply (or other function) each row by all 500 rows, creating 250,000 new rows of data. Each cell needs to function as a constant that is multiplied by all the other cells in the same column (which are not acting as constants). How do I do this efficiently?

    1. I think that an array formula will not help you with this task.

      Please see the following example that may help you:
      https://support.ablebits.com/blog_samples/array-formulas-functions-excel_13_MultiplyEachRow.xlsx

      Enter five values to A1: A5

      Use the following formula to get the first multiplier address in 25 resulting rows:
      ADDRESS(TRUNC((ROW()-6)/5+1,0),1)

      Use this formula to get the second multiplier address:
      ADDRESS(IF(MOD(ROW(),5)=0,5,MOD(ROW(),5)),1)

      To get a value using the address, please enter the INDIRECT function.

      The final formula in rows A6: A31 will be as follows:
      =INDIRECT(ADDRESS(TRUNC((ROW()-6)/5+1,0),1))*INDIRECT(ADDRESS(IF(MOD(ROW(),5)=0,5,MOD(ROW(),5)),1))

      1. That was brilliant, Fedor! I applied your example solution to my dataset and got exactly what I requested. Thanks!

        Unfortunately, I found out that Excel (2007) can only handle 32,000 rows for graphing or statistical analysis. Now am I thinking of condensing the 250,000 rows generated with your formula down to 25,000 rows. This can be done by sorting the dataset, then averaging each successive 10 rows. I tried that, but I am getting a moving average rather than averaging 10 rows to make one new row, then averaging the next 10 rows to make the second new row, and so on.

        Could you suggest an approach? I am sorry to trouble you again, but you are the maestro.

        1. I found a solution that works very well, which I will post in case it is useful to anyone else:
          >>If your data starts from An (where n is 2,3,4,...), use this formula:
          =AVERAGE(INDEX(A:A,n+10*(ROW()-ROW($B$1))):INDEX(A:A,n-1+10*(ROW()-ROW($B$1)+1))
          where you should change n to 2,3,4,...

  22. Unit COR SCM SMH
    CODE 10101 10102 10103
    COR 10101 - (411,876,279) 84,314,441
    SCM 10102 411,906,311 - -
    SMH 10103 (84,314,439) - -

    Which formula works to check Difference between COR with SCM, COR with SMH,SCM with COR, SCM with SMH.

  23. HI, I am currently studying Design & produce business documents.
    I have an excel sheet with name of supplier, product name, unit price, unit sales and Total sales. I have been told to add an subtotal to this spreadsheet, go to subtotal, click on unit sales and total sales, tick replace current subtotals and Summary below data and apply. It gives me a message I can not change part of an array. How to I get around this? Many thanks Leanne Waldron

  24. I've been using array formulas for 13 years and fear a recent (mandatory) upgrade to 2013 may have broken them. Until now, I could enter a formula like

    =SUM(($A:$A=$A2)*($B:$B=$B2)*($C:$C)*($D:$D))
    {using cntrl-shift-enter, of course}
    This would:
    *Allow me to test on multiple conditions vs. columns A and B (etc.)
    *Combine weighted elements across columns C and D (etc.)

    This is simplified for illustration - test values were often fed from drop-downs, and both conditions and products often spanned numerous columns. All worked well, and the ability to specify an entire column made formula entry easy and flexible in the face of varying data counts. Arrays also offered advantages over pivot tables in always refreshing dynamically and offered more persistent & flexible formatting than the fairly rigid pivot table formatting options.

    Now in Excel 2013, this array formula appears to break as text header rows evaluate to errors. Previously, headers led to false conditions equaling zero, and the sum continued to a correct answer. Now, I encounter errors when using the array format or an incorrect final 0 if entering as a non-array SumProduct function & syntax.

    Are there any options to restore the old evaluation rules (False*Text = 0)? I could be precise in choosing only numeric ranges or rewrite as a set of dynamic named ranges, but that's considerable effort for a number of legacy workbooks.

    Thanks in advance for your help!

    1. Newer Excel versions attempt to 'parse' the TEXT cell content as a numeric value before applying the '*' multiply operator, i.e. as if it was implicitly fed to a VALUE() function call and thus produce a #VALUE error for non-numeric strings.

      The way to stop these errors from propagating into your SUM is to use IFERROR(), i.e.

      {=SUM(IFERROR($A:$A=$A2, 0)*IFERROR($B:$B=$B2, 0)*($C:$C)*($D:$D))}

      should work for you.

      Since you use multiply and add operators as AND/OR 'replacements', it's better to write IFERROR(cond, 0) rather than IFERROR(cond, FALSE) as that 'FALSE' would have to be converted to a numeric zero(0) anyway.

      Note that IFERROR will also filter out (and replace by FALSE=0) any NaN's produced by any calculations in the range (#DIV/0 errors, etc.) but I consider that a benefit here.

  25. Many thanks for the valuable hints.
    I'm trying array formulas with (dynamic)named ranges (column names) from an excel (formated) table and I do not get it to work.
    Is it not possible or is there any trick for getting it?

    2. Im having the same issue. Trying to use array formulas to create ranges for an excel chart. It wont allow me to enter it directly in the chart range/s and when I create a named range using the array formula it doesnt work either. (I dont want to alter the original diplayed dataset or create an additional table using the array formula). Is this possible? Any help would be greatly appreciated!

  26. Thanks for all the effort put into developing the tutorial. It write-up and examples and explanations are extremely clear and easy to understand.

  27. I need a function to split the letters of a word in different cells vertically in ms excel
    could you help me with this

    1. Hello!

      I think you can use the LEFT and MID functions. For example:

      Extract the 1st letter: =LEFT(A1, 1)

      Extract the 2nd letter: =MID(A1, 2, 1)

      Extract the 3rd letter: =MID(A1, 3, 1)

      And so on.

  28. I have a data with duplicate name in column A and seal no in column which are unique in nature, can you help me in getting the data horizontally with text in column C falling in vertical below the Names.

    1. Vinay,

      If you want to place the data into separate worksheets based on the name, then please try out our Split Table Wizard.

      If your task is to place all the data into different columns on one worksheet, then you need a VBA script. Sorry we can’t help you with this. Please try to find the solution on mrexcel.com/excelforum.com

  29. Due to the fact that I use the European decimal settings (, for decimal and . for digit grouping) my List separator is ;
    This means that I can only creat vertical arrays, because when I try to create horizontal arrays, for instance ={10,20} and then CTRL+SHIFT+ENTER, I get 10,2 in both cells instead of 10 in the first and 20 in the second.
    How to solve this without changing my decimal setting to a dot?

    Thanks in advance.

    1. Hi Mike,

      This seems to be a common international issue that many users struggle with : (

      Please check out this thread on answers.microsoft.com. The last advice seems to make the best sense:

      If comma is decimal symbol, then \ is used in place of comma in Array.

      If semi colon is decimal symbol, then \ is used in place of semi colon in Array. (Semi colon is row separator)

  30. I´m having problems with the transpose example and using formula debug to get a list of cell values.
    Example:
    formula is =transpose(A3:A15)
    When I hit F9 the cell values are delimited by a \ instead of comma, like this:
    ={“Lebanon”\”Israel”\”Turkey”\”Estonia”\”Sweden”\”Greece”\”Tunisia”\”Russia”\”Middle East”\”Denmark”\”Spain”\”Belgium”\”Poland”}

    Any idea how/where to change that so I actually get a list like this?
    {"Lebanon","Israel","Turkey","Estonia","Sweden","Greece","Tunisia","Russia","Middle East","Denmark","Spain","Belgium","Poland"}

    Using Excel 2013 with English (US) language pack installed on German Win8.1 .

    1. Hi Kristian,

      Most likely the backslash (\) is set as a List separator in your Windows Regional settings. Please check Control Panel > Region and Language > Additional settings. When setting the comma as the List separator, be sure to select some other symbol as the Decimal separator.

  31. Just ran across your blog the other day and it is really insightful. In reference to the "And"/"Or" operator section, is it similar to how you can use a sumproduct and sign to complete a shorter countif without an array?

    ex.
    =SUMPRODUCT(SIGN(FlatD[Grade]=A9)*(FlatD[Attribute]="Projected Spring Lexile")*(FlatD[Value]>=C9))

    Gives me the count of three columns with three different requirements.

    1. Hi Rico,

      Yes, you are right, the SUMPRODUCT function is an alternative to using SUM in array formulas. Your example works with the AND logic, it counts rows when all 3 conditions are met. The SIGN function works similarly to the double unary operator (--) in this case.

  32. YOU ARE SMART GIRLE

  33. Its really worthful stuffs.And its saves time lot at job.
