Highlight partial duplicates same column - google-sheets

I am looking to highlight partial duplicates, Column B will have data that is either a single number or multiple numbers separated with a '/'. I can currently get cells with single numbers to highlight if there's a duplicate. I trying to get cells that have multiple numbers to match with cells with single numbers
Example, cell B4 contains 'valueA' , B7 contains 'valueB/valueA' , B8 contains 'valueA/valueC' and B10 contains 'valueA/valueD/valueE' I would like all 4 cells to highlight the same colour


Try the following CF rule applied to the range B:B
=(B1<>"")*(index(sum(n(countif(split(B:B,"/"),split(B1,"/"))>1))>0))


if you are targeting 12 use:
=REGEXMATCH(TO_TEXT(B1), "12")

how can compare two cells in google sheet with multiple value in every cells

how can compare two cells in google sheets with multiple value in every cells and if even one value in two cells are same its show me match but if in two cells we do not have any same value show me not match.
for example I have these cells in my google sheets:
a1:[1,2,3,4]
b1:5,6,7
a2:[10,12,14,16]
b2:18,14,20
for these cell it should compare a1 and b1 and print not match in c1 then for a2 and b2 print match in c2 because a2 and b2 have a same value 14

you can try this arrayformula in Column C
=MAP(INDEX(REGEXREPLACE(A:A,"\[|\]","")),B:B,LAMBDA(ax,bx,IF(ax="",,IF(ISERROR(FILTER(SPLIT(ax,","),(MATCH(SPLIT(ax,","),SPLIT(bx,","),0)))),"FALSE","TRUE"))))
-

For not matching values-
=TEXTJOIN(",",1,LAMBDA(x,y,FILTER(x,NOT(ISNUMBER(XMATCH(x,y)))))(FLATTEN(SPLIT(SUBSTITUTE(SUBSTITUTE(A1,"[",""),"]",""),",")),FLATTEN(SPLIT(B1,","))))
For matching values-
=TEXTJOIN(",",1,LAMBDA(x,y,FILTER(x,ISNUMBER(XMATCH(x,y))))(FLATTEN(SPLIT(SUBSTITUTE(SUBSTITUTE(A2,"[",""),"]",""),",")),FLATTEN(SPLIT(B2,","))))
Edit: To show TRUE/FALSE try-
=INDEX(LAMBDA(x,y,OR(ISNUMBER(XMATCH(x,y))))(FLATTEN(SPLIT(SUBSTITUTE(SUBSTITUTE(A1,"[",""),"]",""),",")),FLATTEN(SPLIT(B1,","))))

Another approach, based on creating an intermediate 2D array of IFs for each pair of cells to be compared then summing the result; given the columns for comparison in A1:A & B1:B then placing this formula in C1 will spill as many results as required:
=arrayformula(iferror(map(A1:A,B1:B,lambda(a,b,if(sum(n(split(a,"[],")=flatten(split(b,"[],")))),"Match","No match")))))

How to sum numbers within text in google sheets?

Im looking to sum the numbers within a cell of text, into another cell.
Example of Excel

Try
=sum(split(join("|",REGEXEXTRACT(A1,REGEXREPLACE(A1,"([0-9]+)","($1)"))),"|"))

Clear Col C entirely (including the header "TOTAL"). Then place the following formula in cell C1:
=ArrayFormula({"TOTAL"; MMULT(ARRAY_CONSTRAIN(SPLIT(REGEXREPLACE(A2:A,"[^\d]+","~")&REPT("~0",25),"~"),COUNTA(A2:A),25),SEQUENCE(25,1,1,0))})
You can change the header text within the formula itself if you like.
This one formula will produce the header and all results for all rows in Col C.
How It Works
REGEXREPLACE replaces any groupings of anything other than digits with a single tilde (~). To this new string, REPT adds a repeated string of 25 instances of ~0.
SPLIT then splits this at every tilde, which sends each number (and zero appended by REPT into its own column. Some rows at this point will have more columns than others, because you have a different numbers of listed items in each of your A2:A cells.
ARRAY_CONSTRAIN constrains the results into a regular grid with as many rows as there are non-null entries in A2:A and 25 columns. Based on your data samples, this should be more columns than you'd ever have listed items per cell in A2:A. Those REPT zeros will fill in all columns after your last actual value in A2:A.
MMULT can now act on the constrained grid, along with SEQUENCE to do row-by-row addition.

Adding the first digit(s) of a cell ending with specific letter

I have a sheet that has blocks of cells. I add them for a total if they don't contain any letter. Letters signify a specific variable or signifier code for tracking. I also want to add the cell value when a cell has an ending code letter. I've tried SUMIF, Substitute, SumProduct and a few others.
For a while I've used the following which worked till the S value changed to another number than "8" which then gave the wrong sum from the range.
=if(countif(D64:Q64,"*S")=0,"",((countif(D64:Q64,"*S"))*8))
In the cell range I have 5 variable groups ending in a letter (A, H, S, C and R) and one group not ending in any letter.
The formula I use to add the cells not containing a letter but have a value is this
=IF(SUM(AA64,(SUMIF(D65:Q65,"<>")),-(COUNTIF(D65:Q65,">=0")*8))>24,24,(SUM(AA64,(SUMIF(D65:Q65,"<>")),-(COUNTIF(D65:Q65,">=0")*8))))
which adds the table data plus the previous lines table data but does not exceed 24.
H is a set value of 6 and doesn't change.
Does anyone know how to add the value of the cells that contain a specific letter?
N (number)
A
S
C
R
H
8.5
H
8A
2S
9
3C
0.5R
17.5
8
2
3
0.5
6
I'd prefer it be a formula usable in Google Sheets because that is where this data is.

Solution:
You can use this formula below column "N" then drag right until below column "H".
=SWITCH(H$1,"N",SUM($A2:$G2),"H",6,SUM(IFERROR(ARRAYFORMULA(VALUE(LEFT($A2:$G2,FIND(H$1,$A2:$G2)-1))),0)))
This is a combination of three formulas:
If the row above is N, sum A2 to G2. This will ignore all the strings.
If the row above is H, output 6.
Else, get the number to the left of the defined suffix, set all others to 0, and get the sum.
Output:

An alternative could be to use
=SUMPRODUCT(A3:G3, isnumber(A3:G3))
to compute the sum of the cells with numbers only, and to use
=sum(filter(substitute($A$3:$G$3, I$2,)+0, regexmatch($A$3:$G$3, I$2)))
under the 'A' and drag to the right

How do you update range of formula in Google Sheets when you add a row?

I have a column in a Google sheet that has numbers in cells A1-A5. In A7 I show the sum of cells A1-A5 using =SUM(A1:A5). I want to be able to add/remove cells from the A1-A5 range and have A7 behave accordingly.
For example, I want to add a number in A6 by clicking "insert row below" on row 5, and have the sum in A7 move down to A8 and have its formula update to =SUM(A1:A6).
So here's what I have right now:
...and here's the kind of thing I want to be able to add:

instead of your =SUM(A1:A5) use this:
=SUM(INDIRECT("A1:A"&ROW()-1))
this will allow you to get sum of all above regardless if you add or delete rows

How to count rows between 2 non empty cells with their intermediary empty cells in Google Sheets?

I'm trying to count each rows of empty cells between two non-empy cells and adding the upper non empty-cell count (or the lower non-empty cells count) to the result when the empty cells/rows numbers are variable and irregular in this manner:
A1 Empty
A2 Non-empty
A3 Empty
A4 Empty
A5 Empty
A6 Empty
A7 Non-empty
(with A2 to A5 being irregular — could be any number of intermediary empty rows/cells — i.e. 10, 2, 30, 5, etc., and variable — could be located in any location within Column A)
The result should return as follow:
=IFS(
AND(A2="",A3=""),"",
AND(A2="",A3<>""),"",
AND(A2<>"",A3<>""),ROWS(A2),
AND(A2<>"",A3=""),ROWS(A2:UP TO NEXT NON-EMPTY ROW BENEATH (NOT COMPRISED (or minus the next non-empty row(-1)))
How do we program Google Sheets to count rows "UP TO NEXT NON-EMPTY ROW BENEATH (NOT COMPRISED (or minus the next ono empty row(-1)) when the emppty intermediary rows' count is variable/unknown for each occurence and irregular/can be any number of intremediary rows?
I have this data as example:
So far, I've come up with this partial solution:
=IFS(AND(A2="",A3=""),"", AND(A2="",A3<>""),"", AND(A2<>"",A3<>""),ROWS(A2), AND(A2<>"",A3=""),ROWS(A2:UP TO NEXT NON-EMPTY ROW BENEATH (NOT COMPRISED (or minus the next non-empty row(-1)))))
The expected result should return as follows:

Well I think you can do it a bit more elegantly using a reverse lookup. The idea is to sort the data on descending order of row number, then use a match with -1 as the last parameter, which is equivalent to searching from the end of the data for the next non-blank.
=ArrayFormula(iferror(if(A2:A="","",rows(A2:A)+2-match(row(A2:A)+1,
query(SORT({IF(A2:A<>"",row(A2:A),""),row(A2:A)},2,false),"select Col1"),-1)-row(A2:A)),1))
If you wanted to keep it simple and just use a pull-down formula, an ordinary match is enough:
=ArrayFormula(iferror(if(A2="","",match(true,A3:A<>"",0)),1))
(it still has to be entered as an array formula because A3:A<>"" is an array of True and False)

I found a solution with a Monster formula but with simple iterative logics, and up to 50 intermediary blanks (for more only need to make the formula larger).
What I was lookind for was simply to print the cells/rows count of intermediary empty cells between 2 non-empty cells + adding to the count either the 1st non-empty cell or the last non-empty cell.
So for example if cell A1 and cell A9 have 8 empty cells between them, then return 8+1 (or 10-1).
The logics used is simple:
probe how many possible empty cells there can be between each 2 non-empty cells counting the 1st non-empty as well within column A (in the formula below the possibility is up to 50 empty cells), and for each case return the intermediary rows -1 (the last row).

Can it be done in a simpler way but still with a single formula?
Thanks a lot for your next input!

In the mean time I did some simplification of my previous Monster formula and learned the ArrayFormula application in the process.
1st I tried to shorten the big blank cells intervals into ranges formulations to see if it still worked.
For example I changed:
AND(A1<>"",A2="",A3="",A4<>""),ROWS(A1:A4)-1,
into
AND(A1<>"",A2:A3="",A4<>""),ROWS(A1:A4)-1,
And it shortened my formula from this:
to this:
But then when pasting the new formula I got a #VALUE! error 'an array value could not be found'.
After further tests, I used the ArrayFormula and it worked by adapting the simple 'ranges' previously used to Arrays:
from this
AND(A1<>"",A2:A3="",A4<>""),ROWS(A1:A4)-1,
into this
AND(A1<>"",ArrayFormula(A2:A3=""),A4<>""),ROWS(A1:A4)-1,
With this final result:
