Repeating CountIF in Google Sheets (loop a countif) - google-sheets

I want to reference 1 cell, and countif all comma-separated-variables within that cell. I want to do this in Google Sheets (not scripts).
Let's say Cell A1 = PK,COMP. I would want something like:
=COUNTIF(B:B,REPT(INDEX(SPLIT(A1,","),COUNTA(SPLIT(A1,",")),COUNTA(SPLIT(A1,","))))
So in other words, the goal is to get this to loop. It would go through column B:B, count the number of times PK appears... then, next, it would go through column B:B and count the number of times COMP appears.
Is this possible somehow?

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).
The formula:
=IFS(AND(A1="",A2=""),"",AND(A1="",A2<>""),"",AND(A1<>"",A2<>""),ROWS(A1),AND(A1<>"",A2="",A3<>""),ROWS(A1:A3)-1,AND(A1<>"",A2="",A3="",A4<>""),ROWS(A1:A4)-1,AND(A1<>"",A2="",A3="",A4="",A5<>""),ROWS(A1:A5)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6<>""),ROWS(A1:A6)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7<>""),ROWS(A1:A7)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8<>""),ROWS(A1:A8)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9<>""),ROWS(A1:A9)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10<>""),ROWS(A1:A10)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11<>""),ROWS(A1:A11)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12<>""),ROWS(A1:A12)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13<>""),ROWS(A1:A13)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14<>""),ROWS(A1:A14)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15<>""),ROWS(A1:A15)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16<>""),ROWS(A1:A16)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17<>""),ROWS(A1:A17)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18<>""),ROWS(A1:A18)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19<>""),ROWS(A1:A19)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20<>""),ROWS(A1:A20)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21<>""),ROWS(A1:A21)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22<>""),ROWS(A1:A22)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23<>""),ROWS(A1:A23)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24<>""),ROWS(A1:A24)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25<>""),ROWS(A1:A25)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26<>""),ROWS(A1:A26)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27<>""),ROWS(A1:A27)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28<>""),ROWS(A1:A28)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28="",A29<>""),ROWS(A1:A29)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28="",A29="",A30<>""),ROWS(A1:A30)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28="",A29="",A30="",A31<>""),ROWS(A1:A31)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28="",A29="",A30="",A31="",A32<>""),ROWS(A1:A32)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28="",A29="",A30="",A31="",A32="",A33<>""),ROWS(A1:A33)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28="",A29="",A30="",A31="",A32="",A33="",A34<>""),ROWS(A1:A34)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",A15="",A16="",A17="",A18="",A19="",A20="",A21="",A22="",A23="",A24="",A25="",A26="",A27="",A28="",A29="",A30="",A31="",A32="",A33="",A34="",A35<>""),ROWS(A1:A35)-1,AND(A1<>"",A2="",A3="",A4="",A5="",A6="",A7="",A8="",A9="",A10="",A11="",A12="",A13="",A14="",

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

New Sheet here

Repeat conditional formatting formula

I'm using Google Sheets and I have a pattern that repeats every 10 rows: A number in A1 and other stuff in A2:A10. Then the same again: A different number in A11 and other stuff in A12:A20. I want to apply conditional formatting to each block, based on the first number. For example, turn all A1:A10 cells green if A1 is greater than 5. The problem is I want to do it for the whole column and for all new blocks, without having to enter the formula each time a block is added. Is it possible? Thanks

Create a helper column B with this formula:
=INDIRECT("A" & ROUNDUP(ROW(B1),-1)-9)
It will return the value of the first cell in each group, repeated down the column (rows 1:10 will show the value from row 1, etc). Then, apply the conditional formatting based on that column.

How do I organize formulas to work with columns in google sheets

Hi so I'm trying to make a spreadsheet in Google Sheets that takes two numbers and subtracts them and then does it in the next row .
So example the formula in C1 would be "subtract(A1, B1)" in the first row. But then in the next row I would like it to change to "subtract(A2, B2)" and output in C2.
(Without having to go in each C cell and change the formula of course)
So how do I do that and also how do I apply a formula to multiple cells of a row (C1,C2,C3,C4,C5, etc....)

Just put =MINUS(A1,B1) into C1 and then copy it and paste it in the remain rows of column C and the spreadsheet automatically adjusts the row numbers for you.

#Cooper's Answer above is perfect. I'm just giving a alternative here using array formulas, because it's easy.
Put this in D2
=ARRAYFORMULA(MINUS ( B2:B, MULTIPLY( 2.5, QUOTIENT(C2:C,15))))

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)))

Tallying columns using Countif with a variable number of rows

I'm using Google Sheets for a spreadsheet I'm working on.
Basically, I'm counting the number of times some different items (items are all listed in columns) live inside of different application windows (all my windows are listed in rows).
I'm just plopping a checkmark to say yes when an item lives in a window.
I want to tally this, and I'm using Countif like this: =countif(C4:C38,"✔")
However, if I find a new item, or window, everything has to move and I have to update the formula's column or row number.
Is there a way to make the Countif's range dynamic?

To count the checkmarks in column C, irrespective of how many rows are in the sheet:
=COUNTIF(C:C,"✔")
To count the checkmarks from the fourth row down in column C, and not be affected by row insertion/deletion:
=COUNTIF(INDIRECT("C4:C"),"✔")
To count the checkmarks from the fourth row in column C, down to the row above where the formula is placed:
=COUNTIF(INDIRECT("C4:C"&(ROW()-1)),"✔")
