Finding values based off Row and Columns input in Google Sheets - google-sheets

I have a very big correlation matrix that is very hard to navigate.
I want to make two dropdown menus to select two items (X and Y) and need a formula in google sheets to output the corresponding correlation.
I am aware of the method of doing this by putting the row and column number, as described here but I want to put in the values in the row and column, not their number.
I would appreciate the help.
thank you

You just need to use INDEX() with two MATCH() formulas.
The first MATCH() gets the row number for the label you selected
The second MATCH() gets the column number for the second label
For example, if I have my drop-downs in B1 and B2 and the data in a Data! sheet:
=INDEX(Data!A1:ZZ, MATCH(B2,Data!A:A,false), MATCH(B1,Data!1:1,false))

Sum two ranges separately in one formula

How can I do one single formula to sum two ranges and display them in their respective column.
Here I'm using SUM formula in each cell but I'm sure there must be a single formula that can accomplish this.
Value 1 and Value 2 are the ranges to add them together in Sum row.
Here is an example picture.
Since arrayformula does not support sum, I suppose you could also do this in C12:
=arrayformula(C10:I10+C11:I11)
Clear the formula you have in row 12 and then enter in C12
=index(mmult({1,1}, --C10:I11))
Change range to suit and see if that helps?

Google Sheets - How to concatenate values from different rows and columns if the cells meet certain criteria

I am trying to create a formula that concatenates cell values if the ticked box is TRUE Please see attached image click here to see the image
What I am trying to do is to concatenate in one string columns B and C from every row if the checkbox in column A is selected, and have them separated by a ",". You can in cell G2 an example of the final result I am trying to achieve.
You can find the google sheet in this link https://docs.google.com/spreadsheets/d/1hwm4Q89qj3ko2vJ4OASWmgz4VQr_uUaP7E7AmVdl8Ks/edit?usp=sharing
Thanks in advance.
try:
=ArrayFormula(TEXTJOIN(",",1,IF(A4:A,B4:C,)))
You can try this sheet formula first.
=IF(A4="","",IF(A4=TRUE,TEXTJOIN(",",True,B4,C4),""))
This formula has nested IF's just for additional checker to check if the first column has a value and would return blank just for it to be dynamic. You can drag the formula down to adjust the cells.

Google Sheets - Multiply field by field three to the left

My title might not be very specific, so I'm going to try to explain a little better.
The sheet is divided into a name(Column A), containing a certain number of values(Column B), that get added together to a total in Column C. Furthermore, Column D, E and F contains the values I want the Total in Column C multiplied by. These first columns A to F I just fill in manually, but I would like a function to calculate the Columns I've called x, y and z total (G, H and I).
I see a pattern in this, I just can't figure out the syntax to get Sheets to see it aswell.
The pattern I'm invisioning is for each row, I want column G, H and I to take the value 3 fields to their left, and multiply it by Column C, at their row number.
Is this somehow achievable? I tried finding a solution online but I guess I don't know how to word myself.
Here's a picture to maybe make everything a little clearer
This would save me alot of time, given that I have over a hundred different rows this calculation needs to be performed on...
If something is not clear, please feel free to write a comment. I'll be following this thread quite liberally.
Thanks in advance!
You can have this formula on the first xTotal:
cell G2: =ARRAYFORMULA(if(len(C2:C),C2:C*D2:D,))
cell G2: =ARRAYFORMULA(if(len(C2:C),C2:C*E2:E,))
cell G2: =ARRAYFORMULA(if(len(C2:C),C2:C*F2:F,))
I created a sheet with the same results you had before, but this time you don't need vertical columns, just say in the # of Values column how many numbers you should have below. You just need to input the values with the grey columns.
Note: This is assuming you will always have growing vertical numbers like 1,2,3,4,5. In the new sheet you just need to set 5 in the column and it will calculate the result.
Please make a copy of this sheet and edit as you wish.
Sheet
You can use a single, simpler formula for this in cell G2
=ARRAYFORMULA(if(C2:C="",,C2:C*{D2:D,E2:E,F2:F}))

Working with hierarchical data in Google Sheets

If I have hierarchical data in a Google Sheet as in columns A and B in the example below, how can I write a formula that will fill the corresponding cells in column C with the product of the "parent" value in A1, and the "child" values in column B. That is, The formula in C8 for example, will search upward in column A until it finds the value 5 in A6, then multiplies it by 8, the value in B8.
Obviously I'm trying to avoid having to put the "parent" value in every row in column A.
After a fiddling around and jogging my memory on ArrayFormulas I figured out how to get the result I wanted. Here's the formula I'm using:
=ArrayFormula(index($B$2:$B2,MAX(IF(ISNUMBER($B$2:$B2),ROW($B$2:$B2)))-1,1))
(Note: Row 1 contains headings)
Edit: Explanation of how I arrived at this solution:
Ordinarily, IF(ISNUMBER(cell)), and ROW(cell) would return TRUE/FALSE, or a row number respectively. When used in an array formula and a range of cells as input instead, what you get is a list of TRUE/FALSE values, and row numbers evaluated for each cell in the input range. Wrap MAX around that and it will return the position in those two lists where IF(ISNUMBER()) is TRUE and the row number returned by ROW() is the highest, effectively searching from the bottom of the range.
The absolute reference for the first element in the range to be searched (in this case $B$2) keeps the range anchored to the same starting location when dragging the formula into other cells, while the lower bound of the range (in this case $B2) to be searched grows vertically.
Finally, the INDEX takes the input range, row number returned by the above (-1 row because of the header) and column position (1, since there is only one column) in order to return the desired value.
One way you could do this would be to associate each value in column B with a category or key that can be used to lookup the value for A in a separate table. This abstracts it somewhat, so you can change the values for the A column without having to have them in every row, but there's no empty cells.
i.e.
and lookup table:
In column C
= VLOOKUP($A1, <range for category lookup table>, 2, 0) * $B1
(And then this formula can be filled down)
More on VLOOKUP in Google Sheets here
Alternatively I suppose you could use a formula to find the last non-empty row in column A, or something along those lines, but this is more of a hack than a proper way to structure your data. Tables aren't really designed to be used in a hierarchical fashion like what you've shown. But they can easily represent hierarchical data using techniques like what I've suggested.

How to use index match formula that automatically expands in Google Sheets

In Google Sheets I am using a filter function to pull in Names into column A and a Timestamp into column B. Every time a second occurrence of the name shows up into columns A & B of the list I want column C next to the prior occurrence to reference the new timestamp. In column D I will then calculate the difference from the names timestamp and the next occurrence of that same name.
Currently I am using the following formula:
=IFERROR(INDEX(B3:B,MATCH(A2,A3:A,0)))
If I drag this formula down it does what I need it to do, but due to how many rows are being added to the first two columns, rows are being added to the bottom of the sheet due to the filter and the formulas keep needing to be dragged down. The durations in column D are being calculated with the following formula, that automatically arrays the results and automatically expands with the filter results:
=IFERROR(ARRAYFORMULA(IF(C2:C="","",C2:C-B2:B)))
I would like my index match formula to do the same, but it seems I cannot use the index formula with an arrayformula.
I attempted to achieve this by using a vlookup combined with an offset for the range. The first row is giving me the result I want, but all the subsequent rows are not referencing the offset range, probably because the offset isn't changing with each new array result here is that attempt:
=IFERROR(ARRAYFORMULA(VLOOKUP(A2:A,OFFSET(A2:B,1,0),2,FALSE)))
Any ideas how this could be accomplished by placing a formula in one cell, or would this have to be accomplished with a script?
I have added an example spreadsheet of the current method HERE
Thanks in advance for any help.
Formula
Instead of
INDEX, MATCH and OFFSET
try the following formula
=ArrayFormula(IFERROR(VLOOKUP(
TRANSPOSE(VALUE(REGEXEXTRACT(QUERY(TRANSPOSE(
IF(FILTER(ROW(A2:A),LEN(A2:A))<TRANSPOSE(FILTER(ROW(A2:A),LEN(A2:A))),
IF(FILTER(A2:A,LEN(A2:A))=TRANSPOSE(FILTER(A2:A,LEN(A2:A))),
TRANSPOSE(FILTER(ROW(A2:A),LEN(A2:A))),
),)
),,2000000),"(\d+)"))),
FILTER({ROW(A2:A),B2:B},LEN(A2:A)),2,0)))
Formula description
This part creates a square matrix showing the row number of the value that matches if it's below of the current row:
IF(FILTER(ROW(A2:A),LEN(A2:A))<TRANSPOSE(FILTER(ROW(A2:A),LEN(A2:A))),
IF(FILTER(A2:A,LEN(A2:A))=TRANSPOSE(FILTER(A2:A,LEN(A2:A))),
TRANSPOSE(FILTER(ROW(A2:A),LEN(A2:A))),
),)
This part takes the smallest row that matches the current row (the next occurrence of the row value)
TRANSPOSE(VALUE(REGEXEXTRACT(QUERY(TRANSPOSE( ),,2000000),"(\d+)")))
This part returns the related value, if any, otherwise a blank:
IFERROR(VLOOKUP( ,FILTER({ROW(A2:A),B2:B},LEN(A2:A)),2,0)))
