I have a sheet where I load a set of data in. Each column is a category, but I do not know the specific name/headline/title of each column in advance. I can manually translate the column name to a given category and write that in another sheet. Also, I do not know the number of columns and rows in the data set. See the images for an example where I have a data set and a table where I manually type which column is which category.
The data set:
A table where I manually set which column is which category:
Lets say I now want to use the data associated with a specific category (a column) in a formula such that I take the sum of the column with this category (e.g. "Force" in the example which I have manually stated in the other sheet in cell B2 is column B).
The final result should be that I take the sum of column B (where the column letter is read in the other sheet in cell B2) from row 2 to the end of the column. I believe the two things I do not know to make this work is:
How do I use the value in a cell to refer to a column in another sheet?
How do I take the sum of a column from a known start row to the end (unknown number of rows in the data)?
Any help is much appreciated! :-)
You can use INDIRECT:
=SUM(INDIRECT("'Sheet2'!" & B2 & ":" & B2))
But I would recommend, instead of column letter use the column number A=1,B=2,... and use the non volatile INDEX:
=SUM(INDEX(Sheet2!A:I,0,B2))

Please excuse the newbie question, I am very unfamiliar with Excel.
Is there a way for me to input a number value in a cell in column A, and then have columns B-D autofill, according to what the number value in column A is?
If it helps to explain, I service many locations for a retail company. What I'm trying to do is be able to fill in a store number in column A, then have column B-D autofill with the location of store, description of service (2-3 words), and frequency of service.
I have almost 100 stores so it would be a huge time saver if I could just input the number into column A and have the rest of the information fill in automatically. Thanks in advance for your help.
Create a new sheet named Reference, with four columns: Column A: Store Number, Column B: Location, Column C: Service, Column D: Frequency.
Fill out the data in those columns for all 100 stores.
In your other sheet, columns A - B are the same columns. For Store Number, Click in cell A2, Go to 'Data', then 'Data Validation', make it only allow data from a list, set the 'Source' to:
=Reference!$A$2:$A$101
Type the following formula in cell B2 for Location:
=VLOOKUP(A2,Reference!$A$2:$D$101,2, FALSE)
Then just modify that formula for the other cells. (Obviously, if your sheet has this not in cell A2, you'll need to make adjustments, but what you need is here.)
you can use =CellReferenceNumber like on D1 you can use =A1 it will auto fill D1 cell with the data present in A1. You can use references as many as you want.
Would really appreciate some help. Pretty basic problem. In column A I have SSN's, Column B I also have SSN's and in column C I have dates associated with the SSN's in Column B. The problem the 2 different SSN's columns don't match and I need them too. Problem 2: The dates in column C need to stay associated with the same socials in column b.
This is fairly simple.
Either in a new sheet or in separate columns from your original data, create create a column that represents the same column as A or the original SSN's, this can easily be done with a simple reference formula =A1 and autofilled down. You can do the same for the second column that is a copy of the first SSN.
For the third column just use a simple INDEXand MATCHformula like this:
=INDEX(C:C,MATCH(E1,B:B,0))
This formula I have the new data in Columns E-G with this formula in column G.
What this formula is doing is looking for the value of E1 within column B (looking for the value of the first SSN within the span of the column B). It will then grab the date value from column C associated with the found value in B. This will not work if multiple of the same SSN's are found within column B.
Note: You have to set the formatting of the formula cell as a Date
I have a spreadsheet with multiple columns with a few thousand rows and I would like to find the cells that are common across all columns. Is there a function that I can use to check if a cell value exists in a set of cells/column?
To find out if a value exist in all columns but in any row you can put this equation in the next open column and drag down:
=AND(MATCH(A1,B:B,0),MATCH(A1,C:C,0))
This assumes you have data in column A, B & C and the equation is in column D. now you can sort on column D for unique values.
Depending on your data type you might get an error. If that is the case try this:
=AND(IFERROR(MATCH(A1,B:B,0),FALSE),IFERROR(MATCH(A1,C:C,0),FALSE))
I have a table with student IDs separated in groups. I need a handy way to count the total number of students in each group and populate it after the last row of each group (marked with ??)
Currently I just enter =COUNT() and then manually figure out the top and bottom borders of the range for each group. Not convenient at all.
I was thinking that a possible solution could be one of the following:
A some kind of pivot table permutation. I failed on this one.
Excel Data->Outline->Subtotals functions. Again, fail. It keeps creating new rows in my table.
A universal formula that can be pasted into each ?? cell. Not the most graceful solution, but still would do.
A macro. As a last remedy if nothing else works.
The following steps will calculate the subtotals while preserving the structuring and formatting of your worksheet.
Put this formula in cell C1 and copy the formula down the column:
=IF(NOT(ISERROR(SEARCH("Total",A1))),COUNTA(INDIRECT("B"&MATCH(LEFT(A1,LEN(A1)-7),A:A,0)+1&".B"&(MATCH(A1,A:A,0)+1))),IF(B1="","",B1))
Apply a conditional format to cell C1 with the formula rule =(MOD(ROW(C1),2)=0) and blue fill to match the shading on the other rows. Copy the format down the column using Paste Special Format.
Either hide column B, or copy the values in column C to column B using Paste Special Values and hide Column C. If you decide to copy the values to column B, you won't need to set the conditional formats.
Here is what the formula does:
First, check whether the formula's row is a Total row, by searching the cell in column A of the row for the word "Total," using the SEARCH function.
If the word "Total" is found:
Determine the range in the worksheet of the student IDs for the group for that total row:
a) Identify the rows in which the words "GroupX" and "GroupX Total" are found by using the MATCH function. With that, you know that the IDs for the group are in a range that starts at, say, row x and ends at row y.
b) With the starting and ending row numbers, construct the address range in which the IDs lie, which has to be the string "B" + (row x) + "." + "B" + (row y).
c) Turn the string into a range reference that can actually used in a formula using the INDIRECT function.
Count the number of students in the group using the COUNTA function and the range, and show that as the formula's result.
If the word "Total" is not found
Check whether the cell in column B is empty
a) If it is empty, show a blank as the formula's result
b) if it is not empty, it must be a student ID, so show the ID as the formula's result.
Add a column (I usually add it to the LEFT of the existing matrix) where you enter a formula from row 2 onwards that fills the blanks in the old column A. Then the old matrix including your new column can be used in a pivot.
So Insert a column left of your matrix, this is column A now. Put a header in Cell A1, for example "Group Name1"
Enter the following formula in cell B2 and extend it to the end:
=IF(B2="",A1,B2) This way your blanks will be filled.
Now apply a pivot on this matrix and there you are.
Maybe not the nicest looking solution, but its quick and works well.
If u have table like this
Students id Name of students group ........
then u can use countif/countifs formula
I have some data that's structured in a table like this:
.
I have another tab on my spreadsheet where I eliminate any duplicate category entries and want to concatenate the data to look like this:
I need to create this using a function and not a macro or Visual Basic. I've already written the function to eliminate any of the duplicate category entries and now I need to figure out how to take each of those unique categories and append the data behind it. Any ideas?
Assuming the first image comes from Sheet1 and the second Sheet2, here's a way to do it. You need to add at least one calculated column to Sheet1 and optionally two calculated rows to Sheet2.
Uniquely identify each row on Sheet1. Add a new column A with the formula =B3&COUNTIF($B$3:B3,B3) in A3 and fill down. You'll have first1 in A3, first2 in A4 and so on.
Identify each block of columns on Sheet2. Add a new row 6 with the formula =COUNTIF($B$2:B2,B2) in B6 and fill across. The values will be 1,1,1,2,2,2,3,3,3. You can type these in manually if you like but it won't scale as easily.
Work out the column of each data item in Sheet1 and put in the columns for Sheet2. Add a new row 7 to Sheet2 with the formula =MATCH(B2,Sheet1!$A$2:$E$2,0) and fill across. The values will be 3,4,5,3,4,5,3,4,5. We now know, for each cell in Sheet2, which instance of the category we have and in which column the data variable comes from.
Use VLOOKUP to find first1 and return data column 3 within the data table. On Sheet2, set cell B3 to =VLOOKUP($A3&B$6,Sheet1!$A$2:$E$8,B$7,FALSE) and fill down and across.
You'll have a number of #N/A errors (e.g. cell E4). If you have a newer version of Excel, you can use IFERROR() to escape this; otherwise, use =IF(ISNULL(<formula>), "", <formula>) where <formula> is the formula in step 4.
To summarise:
Create a unique, sequential, calculable row ID for each row in the source.
Determine which instance of that sequence is used by each column in the destination. This is appended to the end of the category to determine the row IDs formed in the previous step.
Determine which column contains the data for each column in the destination.
Look up the row with the calculated row ID and find the relevant column for this data item.
Format the results appropriately.
