Excel: Find intersection of a row and a column - excel

My question is how can I find an intersecting cell of a specific column and row number?
My situation is this: with some calculations I find two cells, lets say B6 and E1. I know that I need a row of the first one and a column of the second one. So I could just use ROW and COLUMN functions to get the numbers. After that, I need to find an intersecting cell. Which would be E6 in this example.
I would just use INDEX(A1:Z100;ROW;COLUMN) but I don't know the exact area that I'm going to need - it depends on other stuff. I could use something like A1:XFG65000 but that is way too lame. I could also use a combination of INDIRECT(ADDRESS()) but I'm pulling data from a closed workbook so INDIRECT will not work.
If this would help to know what is this all for - here's a concrete example:
I need to find limits of a section of a sheet that I would work with. I know that it starts from the column B and goes all the way down to the last non-empty cell in this column. This range ends with a last column that has any value in first row. So to define it - I need to find the intersection of this last column and the last row with values in B column.
I use this array formula to find the last column:
INDEX(1:1;MAX((1:1<>"")*(COLUMN(1:1))))
And this array formula to find the last row:
INDEX(B:B;MAX((B:B<>"")*(ROW(B:B)))
Last column results in E1 and last row results in B6. Now I need to define my range as B1:E6, how can I get E6 out of this all to put into the resulting formula? I've been thinking for a while now and not being and Excel expert - I couldn't come up with anything. So any help would really be appreciated. Thanks!

You can use an Index/Match combination and use the Match to find the relevant cell. Use one Match() for the row and one Match() for the column.
The index/match function to find the last cell in a sheet where
column B is the leftmost table column
row 1 is the topmost table row
data in column B and in row 1 can be a mix of text and numbers
there can be empty cells in column B and row 1
the last populated cell in column B marks the last row of the table
the last populated cell in row 1 marks the last column of the table
With these premises, the following will return correct results, used in a Sum() with A1 as the starting cell and Index to return the lower right cell of the range:
=SUM(A1:INDEX(1:1048576,MAX(IFERROR(MATCH(99^99,B:B,1),0),IFERROR(MATCH("zzzz",B:B,1),0)),MAX(IFERROR(MATCH(99^99,1:1,1),0),IFERROR(MATCH("zzzz",1:1,1),0))))
Since you seem to be on a system with the semicolon as the list delimiter, here is the formula with semicolons:
=SUM(A1:INDEX(1:1048576;MAX(IFERROR(MATCH(99^99;B:B;1);0);IFERROR(MATCH("zzzz";B:B;1);0));MAX(IFERROR(MATCH(99^99;1:1;1);0);IFERROR(MATCH("zzzz";1:1;1);0))))

Offset would seem to be the way to go
=OFFSET($A$1,ROW(CELL1)-1,COLUMN(CELL2)-1)
(The -1 is needed because we already have 1 column and 1 row in A1)
in your example, =OFFSET($A$1,ROW(B6)-1,COLUMN(E1)-1) would give the value in E6
There is also ADDRESSS if you want the location: =ADDRESS(ROW(B6),COLUMN(E1)) gives the answer $E$6

The following webpage has a much easier solution, and it seems to work.
https://trumpexcel.com/intersect-operator-in-excel/
For example, in a cell, type simply: =C:C 6:6. Be sure to include one space between the column designation and the row designation. The result in your cell will be the value of cell C6. Of course, you can use more limited ranges, such as =C2:C13 B5:D5 (as shown on the webpage).
As I was searching for the answer to the same basic question, it astounded me that there is no INTERSECT worksheet function in Excel. There is an INTERSECT feature in VBA (I think), but not a worksheet function.
Anyway, the simple spacing method shown above seems to work, at least in straightforward cases.

How can I expand a dynamic range with blanks between cells?

I want to define a dynamic range that will expand the rows and columns of my range whenever a new row or column is inserted. My current formula does not want to expand to cell $T$13. My headers start in row $M$7. How can I adjust my formula?
Formula Being Used
=OFFSET(Sheet1!$M$8,0,0,COUNTA(Sheet1!$M:$M),COUNTA(Sheet1!$1:$1))
I need my range to expand to cell $T$13
Right now, your formula counts the number of text values in column M.
That is not a robust approach because column M contains only five text values, but columns S and T have many more values.
If you don't know which column may have the most number of entries, you can introduce a helper cell in each column that counts the number of entries below. I suggest you insert a new row 2. In column M, for example, put a formula in M2
=counta($M$3:M$99999)
Copy that formula across to column T.
Next you can evaluate which of the columns has the largest number
=max(M2:T2)
This can be plugged into your original formula like this:
=OFFSET(Sheet1!$M$8,0,0,max(M2:T2),COUNTA(Sheet1!$1:$1))
So now, instead of just looking at how many rows are in column M, the formula uses the maximum number of rows in the columns M to S.
You can now hide row 2 if it upsets your worksheet design.
Edit: the mere count of text values with CountA will ignore blank cells and will return incorrect results. You really need a formula to find the row number of the last populated cell in each column.
This should really be a new question, but here goes
If the column has number values you can use
=MATCH(99^99,B5:B999,1)
If the column has text values you can use
=MATCH("zzz",C5:C999,1)
Adjust your ranges accordingly.
I ended up using the solution mentioned by #tevlyn.
In range$M2:$T2
I have the follolwing formula =IFERROR(MATCH(99^99,M$8:M$999,1),0).
I've added IFERROR because my data doesn't always have data stretched to $T2.
I then defined my range in name manager using:
=OFFSET(Sheet3!$M$8,0,0,MAX(Sheet3!$M$2:$T$2),COUNTA(Sheet3!$1:$1))
This still works even if there are blanks in between the range.

Check if text exist in rest of Column, and if so, use info from that row it is in

I'm after a way to a cell to check another cell that I'm inputting text into, and for it to see if that text value is the same anywhere else in the column, and if so, it grabs the number value which is in the same column as itself but in the row of the text that checked for.
So if you use picture, you can see I've currently got E7 selected. I'm wanting it to check the "GOLF COURSE" column for any other row that contains the same text it has in it's own row. For this it's "Course1". I'd like it to check through the rest of column B if there are any matches for "Course1" which there is in B3. If it matches I'm wanting it to then use the value that's in same column as it (E) but the same row as the matched text in column B. In this case I would want it to copy the value that is in E3.
If there wasn't a match (as it's a new course lets say) then I need to be able to just click on the cell and input the numbers needed, which I would be able to do anyway but just throwing it in for sake of info.
I've tried all sorts of googling and thinking how I could possibly do it but it's too difficult for my amateur knowledge of Excel.
I believe you are looking for INDEX/MATCH:
=IF(COUNTIF($B:$B,$B7)>1,INDEX(E:E,MATCH($B7,$B:$B,0)),"New")
I added a COUNTIF check to ensure that the same course exists more than once in column B, without it, you would be getting a circular reference formula (which would also happen with the above formula if the same course appears more than once, but you use this formula on the first occurrence of that course, so make sure do not use it the first time you fill out the PAR scores for a particular course).
Merged Cells Messing With INDEX/MATCH
The Formula
Copy the following formula into cell E7:
=IF(AND($B7<>"",$D7="Par"),IF(ISERROR(MATCH($B7,$B$3:$B5,0)),"Par",INDEX(E$3:E5,MATCH($B7,$B$3:$B5,0))),IF(AND($B6<>"",$D7="Strokes"),IF(ISERROR(MATCH($B6,$B$3:$B4,0)),"Strokes",INDEX(E$3:E4,MATCH($B6,$B$3:$B4,0)+1)),""))
Image
How
We are creating the formula in cell E7.
MATCH
Syntax: MATCH(lookup_value,lookup_array,match_type)
We will use MATCH to find the position of COURSE1 in the above
cells of column B.
The 1st argument is lookup_value which will be the cell in the same
row of our row (7) in column B: B7 where we will lock only the
column (we will not be searching in other columns): $B7.
The 2nd argument lookup_array will be a range. The first cell will be
cell B3 whose row and column we'll lock, because we will always
start the search from this cell in every other cell to the left or
below: $B$3. The last cell will be B5 where we will lock only the
column: $B5.
And finally we will use 0 as the parameter of the 3rd argument
match_type to find an exact match.
Now were ready to write our MATCH formula:
=MATCH($B7,$B$3:$B5,0)
Which will return 1 i.e. an exact (0) match of B7 was found
in the 1st cell of range B3:B5.
We don't want 1 (E3), but the value in the cell (5).
INDEX
The INDEX function has 2 syntaxes where we will use the 2nd:
Syntax 2: INDEX(reference,row_num,column_num,area_num)
Since were using a one-column range we can safely omit the arguments row_num and column_num, which leaves us with:
Modified Syntax: INDEX(reference,area_num)
The INDEX function used this way will return the area_num-th value
of reference i.e. in our case if area_num is 1 it will return the
1st value in our column range, if it is 2, then the 2nd, etc.
The 1st argument reference will be the same sized range of our
MATCH range in column E: $E$3:$E5 where we will remove the
column locks because we also want to return results for other
columns: E$3:E5.
The 2nd argument area_num will be our MATCH formula.
Our current formula looks like this:
=INDEX(E$3:E5,MATCH($B7,$B$3:$B5,0))
which will return the value of cell E3: 5.
Final Adjustments: IF, AND and ISERROR
That would have been almost (Error Checking) all if the cells in column B weren't merged. Therefore we have to use IF to determine if the row in which we're writing the formula contains either Par or Strokes and adjust our so far created formula for both conditions:
=IF($D7="Par",INDEX(E$3:E5,MATCH($B7,$B$3:$B5,0))
=IF($D7="Strokes",INDEX(E$3:E4,MATCH($B6,$B$3:$B4,0)+1)
=IF($D7="Par",INDEX(E$3:E5,MATCH($B7,$B$3:$B5,0)),$D7="Strokes",INDEX(E$3:E4,MATCH($B6,$B$3:$B4,0)+1))
and (3rd condition) check in column B if there is a value in the row where we're creating the formula for a row containing Par, or the row above for a row containing Strokes, using AND:
=IF(AND($B7<>"",$D7="Par"),INDEX(E$3:E5,MATCH($B7,$B$3:$B5,0)),IF(AND($B6<>"",$D7="Strokes"),INDEX(E$3:E4,MATCH($B6,$B$3:$B4,0)+1),""))
Finally we have to add some error checking, because if the match was not found the formula will produce and #N/A error:
=IF(AND($B7<>"",$D7="Par"),IF(ISERROR(MATCH($B7,$B$3:$B5,0)),"Par",INDEX(E$3:E5,MATCH($B7,$B$3:$B5,0))),IF(AND($B6<>"",$D7="Strokes"),IF(ISERROR(MATCH($B6,$B$3:$B4,0)),"Strokes",INDEX(E$3:E4,MATCH($B6,$B$3:$B4,0)+1)),""))
Now we are ready to copy the formula to the right and below as far as we need.

How to compare each cell with each other in MS Excel?

In large dataset - 250 rows and 1000 columns I need to compare each value in cell with each other in one column and iterate over all column. Heres simplified example of source data:
And this is what I need (formatting not necessary and 2 empty rows not necessary) - if match if found "1" is produced, if no match "2" is produced, if one or both were N/A - "3" is produced:
Comparison should only be "one sided" for example Terry and Joey is the same as Joey and Terry, thus further comparison of already compared pairs is not needed.
Is it possible to do this in Excel 2016 or are there better tools for this?
My thanks to all.
This alternative is a bit complex, but we all solve problems like this differently. If it helps you, please feel free to use it. If not, I can understand since some of these techniques are not particularly common and the resulting formula is a bit unreadable. I did it this way so that I would be able to organize the rows better and read the matching/unmatching indicators more easily. I started by creating a helper column rather than repeat the rows for each individual so that each row shows the two names being compared. This is the formula I used to compare using B8's information is:
=IF(OR(INDIRECT("R"&MATCH($I8,$A$1:$A$6,0)&"C"&COLUMN(),FALSE)="N/A",INDIRECT("R"&MATCH($A8,$A$1:$A$6,0)&"C"&COLUMN(),FALSE)="N/A"),3,IF(INDIRECT("R"&MATCH($I8,$A$1:$A$6,0)&"C"&COLUMN(),FALSE)<>INDIRECT("R"&MATCH($A8,$A$1:$A$6,0)&"C"&COLUMN(),FALSE),2,1))
I am going to try to explain the formula I used as follows:
Without using the helper column, the basic formula for cell B8 is this:
=IF(OR(B$2="N/A",B3="N/A"),3,IF(B$2<>B3,2,1))
and this would work for the range B8:H11. However, when I skip down to B13, the formula would need to change to:
=IF(OR(B$3="N/A",B4="N/A"),3,IF(B$3<>B4,2,1))
and this would work for the range B13:H15. Likewise B17, and B20 would be:
=IF(OR(B$4="N/A",B5="N/A"),3,IF(B$4<>B5,2,1))
=IF(OR(B$5="N/A",B6="N/A"),3,IF(B$5<>B6,2,1))
for their respective ranges. I shy away from formulas where I have to remember what I need to change for each section (heaven forbid I should write any notes or read them if I did).
In order to do this, I used the person column (A) and my helper column (I) to determine which rows to compare.
MATCH($I8,$A$1:$A$6,0)
gives the row of the person value in the Chart from A1:H6 in the comparison
MATCH($A8,$A$1:$A$6,0)
gives the row of the helper value in the Chart from A1:H6 in the comparison
Since the data being compared is always in the same column, I just use COLUMN() to determine which column to use.
In cell B8, MATCH($I8,$A$1:$A$6,0) will tell me it is row 2 and MATCH($A8,$A$1:$A$6,0) will tell me it is row 3. Thus, I want to use the values in Row 2, Column 2 compared against Row 3, Column 2.
To tell Excel to compare Row 2, Column 2 against Row 3, Column 2 is fairly simple, but creating a formula that you can copy from cell to cell without having to modify it each time is not as easy, since each section is a bit different and there could be blank rows in between sections. What I did was to use indirect cell notation using "R1C1" syntax rather than the more common "A1" cell referencing.
In other words in column B8 this:
INDIRECT("R"&MATCH($I8,$A$1:$A$6,0)&"C"&COLUMN(),FALSE)
gives the value in Row 2 (for Terry), Column 2 and
INDIRECT("R"&MATCH($A8,$A$1:$A$6,0)&"C"&COLUMN(),FALSE)
gives the value in Row 3 (for Joey), Column 2 and
In both of the above, I am concatenating and R and a C to the numbers returned by the MATCH() and COLUMN() functions and using the FALSE parameter to tell Excel to treat the concatenated result as "R1C1" notation. In other words, this:
OR(INDIRECT("R"&MATCH($I8,$A$1:$A$6,0)&"C"&COLUMN(),FALSE)="N/A",INDIRECT("R"&MATCH($A8,$A$1:$A$6,0)&"C"&COLUMN(),FALSE)="N/A")
translates to this:
OR(R2C2="N/A",R3C2="N/A")
I realize that the helper column is a burden you did not ask for and I realize that the formula is overly complicated, but I can freely copy this formula to any column that has the two names and it will do a comparison for that day of the week.
Here is a picture of what I am describing:
Added comments
Just to carry the above a bit further, suppose you had a Sheet1 which had the rows of data to be compared and suppose this were limited to 250 rows with the same 7 columns (rather than 1000). I could create another sheet similar to the above along with another helper cell (I put it in A1) to automatically populate the person column and the helper column like this:
New Helper Cell value: 1 (essentially saying to start at the top). This would populate Cell A2 with the following formula:
=IFERROR(IF(INDEX(Sheet1!$A$1:$A$250,NUMBERVALUE(RIGHT($A$1,3)+ROW()))=0,"",INDEX(Sheet1!$A$1:$A$250,NUMBERVALUE(RIGHT($A$1,3)+ROW()))),"")
Basically this is just this formula:
=INDEX(Sheet1!$A$1:$A$250,NUMBERVALUE(RIGHT($A$1,3)+ROW()))
but is checking first to see if it results in zero and then is replacing it with blanks if it is an error. Copying this cell down Column A will populate that column with the names starting at the first row after the data row specified by A. If you have more headings or other data you would need to add additional amountst to the +ROW() portion in both occurrences in the formula. Column I gets populated siimilarly with this:
=IF(A2="","",INDEX(Sheet1!$A$1:$A$250,NUMBERVALUE(LEFT($A$1,3)+1)))
However, this value does not vary from row to row.
Now that the helper columns are populated, you can populate the formula a bit differently from the above (which had used the same sheet) for example in B2:
=IF($A2="","",IF(OR(INDIRECT("Sheet1!R"&MATCH($I2,Sheet1!$A$1:$A$250,0)&"C"&COLUMN(),FALSE)="N/A",INDIRECT("Sheet1!R"&MATCH($A2,Sheet1!$A$1:$A$250,0)&"C"&COLUMN(),FALSE)="N/A"),3,IF(INDIRECT("Sheet1!R"&MATCH($I2,Sheet1!$A$1:$A$250,0)&"C"&COLUMN(),FALSE)<>INDIRECT("Sheet1!R"&MATCH($A2,Sheet1!$A$1:$A$250,0)&"C"&COLUMN(),FALSE),2,1)))
The main difference from the first formula is the off sheet references to "Sheet1" that were added and the extension of the formula to cover 250 rows.
Here is a picture with Cell A1 set to 1:
Here is a picture with Cell A1 set to 3:
Using this, your Sheet1 values remain where they are and you can create a generic comparison sheet to compare the values of various rows of Sheet1. These can be dynamically built by changing the value in A1 or you can create dozens of similar sheets, each differing by the value in A1.
Not sure if any of this makes sense.
Good Luck
Just use a function like this(exemple for cell B4):
=IF(B3=B2;1;IF(B3="N/A";3;2))
Print of it working
Do it for each line and just drag it from the begining to the end.
EDIT: You should do an or in the 2nd if to make surre neither is "N/A"
=IF(OR(B3="N/A";B2="N/A";3;IF(B3=B2);1;2))

Offset formula logic clarity

I am trying to get year to desired month total of personal expenditure sub categories. After researching stackoverflow, I found a formula seemingly appropriate for my requirements. I found it shifting the desired area by one row down during formula evaluation. I modified the formula by hit and trial on adhoc basis which is giving the correct results. To me the initially chosen formula appeared quite appropriate. I have shown below the sample data sheet and the evaluation steps of the original and modified formula. Could someone explain particularly the offset portion as to why it was going wrong for the initially chosen formula and how the modification helped in solving the problem. Somehow I am not able to get conceptual clarity on this issue.

Personal_Accounts evaluated with formula A
Personal_Accounts evaluated with modified formula
Offset works by specifying:
A cell from you which you will offset (A1 in this example) then specifying how many rows and columns to move from that position, and then how tall and wide to make the range.
The number of rows to move down: In this case the number of rows down is determined by Match(). Match() here will return the number of rows down in the range A1:A9 that the value SS can be found. The answer is 5. Offset now is looking at Range A1 + 5 rows: A6
The number of columns to move across: Here we move 1 column. No funny business. New range is B6
The number of rows to include in the range from that start point: Here COUNTIFS() is used to return the number of times SS is found in the range A2:A9. The answer is 3. So the range will start at B6 and include three rows down in the range. Essentially B6:B8.
Finally, the number of columns to include in the range: Here it's 7 since that's what you have in cell A13, so your range is now B6:H8
OFfseT() returns that range and Sum sums it up
You subtracted one from the results of MATCH() and correctly moved that formula to produce B5:H7. You could have also changed the search range in MATCH() to A2:A9, which would probably make more sense from a readability standpoint.
Lastly, your COUNTIFS() could just be COUNTIF() since you are not evaluating multiple conditions.
So if I had to write this from scratch, I would use:
=Sum(Offset(A1, Match(A2:A9, A12, 0), 1, Countif(A2:A9, A12), A13)
Which will get you the same correct answer, without any math on Match() results.
Offset has two main functions - either to move to cell (target) using specified number of rows and columns from the starting point, or to select range of specified number of rows and columns starting in the target cell. Your original formula has issue in this part
MATCH(A12;A1:A9;0)
matched cell is fifth therefore the offset moves 5 rows down ending in A6, because it starts in A1 + 5 rows. Then it moves 1 column to be in B6 and then creates range of 3 rows in total and 7 columns = B6:H8. So you need to deduct 1 from the result of the match function to end up in the right row.
For better understanding imagine if the SS value was in the first row of the range A1:A9 (in A1) - then the offset would move from A1 one row down to A2 although you wouldnt want it to move at all.
look at your basic offset formula definition.
Offest (REFERENCE CELL, HOW MANY ROWS TO MOVE FROM REFERENCE, HOW MANY COLUMNS TO MOVE FROM EFERENCE, HOW MANY ROWS TO RETURN, HOW MANY COLUMNS TO RETURN)
so if you set your reference cell to A1 and you want to return the result in A2, you need to move down 1 row from your reference cell.
OFFSET ($A$1,1,0,1,1)
Now if we look at the match portion of your equation, MATCH return what position the information is in. So if we want to find the match position of the information in A2 in a range going from A1:A100, Match is going to tell you that the information in A2 is in the 2nd position of the column. Or more precisely it returns a value of 2.
So now we need to tell offset how far down to reach the 2nd position. We dont actually want it to move down 2 rows to get to the second position since our reference point is A1 which is the first row. As a result we really want to go down 1 row to get to the second row. So you want 1 less from your match results which you correctly did by doing Match(...)-1

Adding all the values below the current cell in Excel

I am trying to display the total sum of all the numbers for a particular column. I want the sum to be displayed above the column as follows:
21 30
A B
6 5
6 10
6 10
3 5
I know I can sum the values and display it at the bottom of the column using =SUM(A3:INDIRECT("D"&ROW()-2)), however I am not getting a way to display it at the top of the column.
Please guide.
Based on the comments and the previous answers I suggest following formula, entered in cell A1:
=SUM(OFFSET(A$2,0,0,ROWS(b:b)-1))
You can then copy/paste to the right till second last column.
You could also modify your formula in A1 like this to achieve the same:
=SUM(INDIRECT("A2:A"&ROWS(A:A)-2))
But then you cannot copy/paste to the right...
A more general approach with your idea would be:
=SUM(INDIRECT(ADDRESS(ROW()+1,COLUMN())&":"&ADDRESS(ROWS(A:A),COLUMN())))
You can then copy/paste to the right till last column.
Some explanations:
Both formula sums up every value in the range from A2 till the bottom of column A (i.e. for Excel 2010 this would be A2:A1048576)
It doesn't matter if there are blanks or cells without value; the formula sums up only the numbers
I put A$2 and B:B in the OFFSET formula to avoid circular references, since I'm writing in cell A1 and I cannot write A$1 nor A:A
With the INDIRECT formula you don't have to worry about circular references
Further commenting (sorry, I don't have the credits to comment at the right place under the question):
Phylogenesis formula =SUM(A3:A65535) could also do the work, isn't it?
Didn't understand your question at first, because you talk of "sum of all the numbers for a particular row" but then you sum columns, isn't it?
When I'm doing something like this, I prefer to not include any empty cells beneath the range I'm summing, because I've had errors in the past as the result of including them (usually because there's a cell way down in the column somewhere that I'm not expecting to have a value). I'm assuming that A & B are your column headers. Assuming that, here is how I would do it. This is your formula for cell A1:
=SUM(OFFSET(A$1,2,0,COUNTA(A$3:A$65535)))
Explanation
I'm updating this with a brief explanation, per the OP's request.
According to ExcelFunctions.net:
The Excel Offset function returns range of cells that is a specified number of rows and columns from an initial supplied range.
The function reference for OFFSET is:
=OFFSET(reference, rows, cols, [height], [width])
What this formula does is create a dynamic range based on the number of cells in the selection, relative to cell A$1. This is an offset of two rows and no columns, which starts the range at A$3. The height of the range is the total number of filled cells in the range A$3:A$65535. The assumption here is that there are no blank cells in the range, which there were not in the sample data.
