I am having some difficulties summing up some values in Google Sheets. In my spreadsheet, from multiple other tabs, values and bonuses are combined into one cell (Cell B1 in this example). The format of each "unit" of data is Name,5%xxx (Where "Name" is the name of the item, "5%" represents the sum I want to add, mostly always a percentage, and "xxx" separates one unit from the next). As you can see in cell B1, there are two instances where "Parkour" receives a bonus to sum up (from different sources).
Parkour,5%xxxParkour (Subskill: Sense of Balance),10%xxxParkour,2%xxx
Parkour
0.07
Parkour (Subskill: Sense of Balance)
H2H Combat: Parkour
The formula in cell B2 is:
=IFERROR(SUM(ARRAYFORMULA(IFERROR(VALUE(MID(FILTER(SPLIT(TEXTJOIN("",TRUE,filter(B$1,regexmatch(B$1,$A2)=TRUE)),"xxx"),SEARCH($A2,SPLIT(TEXTJOIN("",TRUE,filter(B$1,regexmatch(B$1,$A2)=TRUE)),"xxx"))),len($A2)+2,1000)),""))),"")
(Dragged down through the rest of the list) (Could not figure out how to make the formula "in line" on the question.)
Expected Results:
B2 = .07 (Working)
B3 = .1 (Not working)
B4 = Blank (Working)
The goal of the formula is to look into cell B1, and split everything out by "xxx". Then, filter the array of items with only exact matches with the line item in column A, then split again by the comma and add up those values. It worked for the first line item, but not the second. (Unsure why, but I strongly believe it has something to do with the parenthesis. When I removed the parenthesis from the name in Column A (and adjusted cell B1 to not have parenthesis), it worked. However, given the structure of the data, parenthesis are required, and I need to find a way for it to work with them.)
When I removed the IFERROR wrap around it in cell B3, I get this error note:
Function SUM parameter 1 expects number values. But " is a text and cannot be coerced to a number.
Any help is greatly appreciated.
You may find useful combining SPLIT with QUERY like this. It will group names and sum percentages:
=QUERY(INDEX (IFERROR(SPLIT(FLATTEN(INDEX(SPLIT(B1:B100,"xxx"))),","))),"SELECT Col1,SUM(Col2) where Col1 is not null group by Col1")
PS: invented a couple of extra line
UPDATE
I've thought you had another goal, try this formula. Having the previous chart generated by QUERY, I used VLOOKUP to match first column and return second one:
=INDEX(IFERROR (VLOOKUP(A2:A,QUERY(INDEX (SPLIT(FLATTEN(SPLIT(B1,"xxx")),",")),"SELECT Col1,SUM(Col2) where Col1 is not null group by Col1"),2,0)))
I can't seem to find the right equation to find a cell from a row that matches only a few specific characteristics. In this example, I am trying to find the equation for Column D which would be the cell in A that has the same cells for B & C.
Hope this makes sense!
I'll provide two options.
If you're sure your data will only ever have zero or one match, you can place the following formula into D2 of an otherwise empty range D2:D...
=ArrayFormula(IF(A2:A="",,SUBSTITUTE(VLOOKUP(B2:B&C2:C,{B2:B&C2:C,A2:A},2,FALSE)&VLOOKUP(B2:B&C2:C,SORT({B2:B&C2:C,A2:A,ROW(A2:A)},3,0),2,FALSE),A2:A,"")))
However, if you think more than one match may turn up and you want "None" to be returned if there is no match, you can use the following formula in D2 or an otherwise empty range D2:D...
=ArrayFormula(IF(A2:A="",,REGEXREPLACE(REGEXEXTRACT(REGEXREPLACE(SUBSTITUTE(VLOOKUP(B2:B&C2:C,TRIM(SPLIT(FLATTEN(QUERY(QUERY({B2:B&C2:C&"~",A2:A&","}, "Select MAX(Col2) where Col2 IS NOT NULL GROUP BY Col2 PIVOT Col1"),, 9^9)),"~")),2,FALSE),A2:A,""),"^[,\s]+$","None"),"([^,\s].+[^,\s])[,\s]*$"),"[,\s]+",", ")))
The second formula will work even if there will only ever be zero or one match; it's just not necessary to have it be that lengthy. And the second formula is only as lengthy because it was unclear from your posted examples whether the data in Col A, B and C will really only ever be one word or not; so the formula is built to assume there will not always be one-word strings in those columns.
Either formula will provide results for the entire column without dragging.
Here's an option, You can use this formula in column D2:
=iferror(textjoin(", ",true,query($A$2:$C,"Select A where A is not null and A != '"&$A2&"' and B = '"&$B2&"' and C = '"&$C2&"'",0)),"None")
Limitation:
You need to manually drag the formula to its succeeding rows. Arrayformula() cannot be used in looping the query string values.
What it does?
Using query(), filter the data from A2:C that has the same current row last name(Column B) and food(Column C) at the same time having a different first name(Column A)
If there are multiple results, use textjoin() to combine them with ", " as its delimiter.
If there is no matched found, it will return an error, hence use iferror() to set the default value to "None"
Output
I'm learning basic =ARRAYFORMULA usage for a finance spreadsheet:
https://docs.google.com/spreadsheets/d/12cAGuUBzIo0LPbmtqWJZNFgjt94f1ybGoj6x2g0c2Y0/edit?usp=sharing
First, I used =GOOGLEFINANCE at B1 to pull up stock prices for a given date range in Column C
=GOOGLEFINANCE(A1,"price",DATE(2020,1,1),DATE(2020,5,30),"DAILY")
Then, I used simple arithmetic to multiply by number of shares at D2 and dragged the formulas down to get a nice column of values
=C2*20
Then, I used INDEX and COUNTA to pull out the last value of Column D at F3 === Great!
=INDEX(AAPL!D2:D,COUNTA(AAPL!D2:D),1)
Next, I turned my arithmetic formula into an ARRAYFORMULA at G2 === Cool!
=ARRAYFORMULA(C2:C103*20)
Of course, the problem with that ARRAYFORMULA is that I would have to manually change the array name in G2 every time the date range updated.
That is, instead of C2:C103, I would need to change the reference to C2:104 to get the columns to match === Rookie mistake!!!!!
So, I got smart with an ARRAYFORMULA containing a IF(ISBLANK(),...,...) at J2
=ARRAYFORMULA(IF(ISBLANK(B2:B),"",C2:C*20))
Column J stays fully populated with the correct values for any date range === !!!!!!!
But now the =INDEX(AAPL!J2:J,COUNTA(AAPL!J2:J),1) at L3 can't find the last value in Column J
Whaaat???
I've tried everything I can think of
It works if I use =INDEX(AAPL!J2:J104,COUNTA(AAPL!J2:J104),1) but that would defeat the purpose, since the reference J:J104 is going to change as the dates change
WHY???
I get the same results in both cells "L3" and "L5" when using:
=ARRAYFORMULA(IF(ISBLANK(B2:B),,C2:C*20))
Check that you are not returning a blank string ("") in your IF like: "=ARRAYFORMULA(IF(ISBLANK(B2:B),"",C2:C*20))" doing so will fill the cells up to the last row in the sheet with empty strings, thus when you use COUNTA(AAPL!J2:J),1) you get a lot more cells than you would expect, these extra cells are the ones you filled with blank strings in the array formula.
On the contrary when you limit the =INDEX(AAPL!J2:J104,COUNTA(AAPL!J2:J104),1) to cells with numbers only it doesn't mix strings and numbers in the calculation and you are naturally get the expected results.
I use the following function
=DAYS360(A2, A35)
to calculate the difference between two dates in my column. However, the column is ever expanding and I currently have to manually change 'A35' as I update my spreadsheet.
Is there a way (in Google Sheets) to find the last non-empty cell in this column and then dynamically set that parameter in the above function?
There may be a more eloquent way, but this is the way I came up with:
The function to find the last populated cell in a column is:
=INDEX( FILTER( A:A ; NOT( ISBLANK( A:A ) ) ) ; ROWS( FILTER( A:A ; NOT( ISBLANK( A:A ) ) ) ) )
So if you combine it with your current function it would look like this:
=DAYS360(A2,INDEX( FILTER( A:A ; NOT( ISBLANK( A:A ) ) ) ; ROWS( FILTER( A:A ; NOT( ISBLANK( A:A ) ) ) ) ))
To find the last non-empty cell you can use INDEX and MATCH functions like this:
=DAYS360(A2; INDEX(A:A; MATCH(99^99;A:A; 1)))
I think this is a little bit faster and easier.
If A2:A contains dates contiguously then INDEX(A2:A,COUNT(A2:A)) will return the last date. The final formula is
=DAYS360(A2,INDEX(A2:A,COUNT(A2:A)))
Although the question is already answered, there is an eloquent way to do it.
Use just the column name to denote last non-empty row of that column.
For example:
If your data is in A1:A100 and you want to be able to add some more data to column A, say it can be A1:A105 or even A1:A1234 later, you can use this range:
A1:A
So to get last non-empty value in a range, we will use 2 functions:
COUNTA
INDEX
The answer is =INDEX(B3:B,COUNTA(B3:B)).
Here is the explanation:
COUNTA(range): Returns number of values in a range, we can use this to get the count of rows.
INDEX(range, row, col): Returns the content of a cell, specified by row and column offset. If the column is omitted then the whole row is returned.
Examples:
INDEX(A1:C5,1,1) = A1
INDEX(A1:C5,1) = A1,B1,C1 # Whole row since the column is not specified
INDEX(A1:C5,1,2) = B1
INDEX(A1:C5,1,3) = C1
INDEX(A1:C5,2,1) = A2
INDEX(A1:C5,2,2) = B2
INDEX(A1:C5,2,3) = C2
INDEX(A1:C5,3,1) = A3
INDEX(A1:C5,3,2) = B3
INDEX(A1:C5,3,3) = C3
For the picture above, our range will be B3:B. So we will count how many values are there in range B3:B by COUNTA(B3:B) first. In the left side, it will produce 8 since there are 8 values while it will produce 9 in the right side. We also know that the last value is in the 1st column of the range B3:B so the col parameter of INDEX must be 1 and the row parameter should be COUNTA(B3:B).
PS: please upvote #bloodymurderlive's answer since he wrote it first, I'm just explaining it here.
My favorite is:
=INDEX(A2:A,COUNTA(A2:A),1)
So, for the OP's need:
=DAYS360(A2,INDEX(A2:A,COUNTA(A2:A),1))
If the column expanded only by contiguously added dates
as in my case - I used just MAX function to get last date.
The final formula will be:
=DAYS360(A2; MAX(A2:A))
Here's another one:
=indirect("A"&max(arrayformula(if(A:A<>"",row(A:A),""))))
With the final equation being this:
=DAYS360(A2,indirect("A"&max(arrayformula(if(A:A<>"",row(A:A),"")))))
The other equations on here work, but I like this one because it makes getting the row number easy, which I find I need to do more often. Just the row number would be like this:
=max(arrayformula(if(A:A<>"",row(A:A),"")))
I originally tried to find just this to solve a spreadsheet issue, but couldn't find anything useful that just gave the row number of the last entry, so hopefully this is helpful for someone.
Also, this has the added advantage that it works for any type of data in any order, and you can have blank rows in between rows with content, and it doesn't count cells with formulas that evaluate to "". It can also handle repeated values. All in all it's very similar to the equation that uses max((G:G<>"")*row(G:G)) on here, but makes pulling out the row number a little easier if that's what you're after.
Alternatively, if you want to put a script on your sheet you can make it easy on yourself if you plan on doing this a lot. Here's that scirpt:
function lastRow(sheet,column) {
var ss = SpreadsheetApp.getActiveSpreadsheet();
if (column == null) {
if (sheet != null) {
var sheet = ss.getSheetByName(sheet);
} else {
var sheet = ss.getActiveSheet();
}
return sheet.getLastRow();
} else {
var sheet = ss.getSheetByName(sheet);
var lastRow = sheet.getLastRow();
var array = sheet.getRange(column + 1 + ':' + column + lastRow).getValues();
for (i=0;i<array.length;i++) {
if (array[i] != '') {
var final = i + 1;
}
}
if (final != null) {
return final;
} else {
return 0;
}
}
}
Here you can just type in the following if you want the last row on the same of the sheet that you're currently editing:
=LASTROW()
or if you want the last row of a particular column from that sheet, or of a particular column from another sheet you can do the following:
=LASTROW("Sheet1","A")
And for the last row of a particular sheet in general:
=LASTROW("Sheet1")
Then to get the actual data you can either use indirect:
=INDIRECT("A"&LASTROW())
or you can modify the above script at the last two return lines (the last two since you would have to put both the sheet and the column to get the actual value from an actual column), and replace the variable with the following:
return sheet.getRange(column + final).getValue();
and
return sheet.getRange(column + lastRow).getValue();
One benefit of this script is that you can choose if you want to include equations that evaluate to "". If no arguments are added equations evaluating to "" will be counted, but if you specify a sheet and column they will now be counted. Also, there's a lot of flexibility if you're willing to use variations of the script.
Probably overkill, but all possible.
This works for me. Get last value of the column A in Google sheet:
=index(A:A,max(row(A:A)*(A:A<>"")))
(It also skips blank rows in between if any)
This seems like the simplest solution that I've found to retrieve the last value in an ever-expanding column:
=INDEX(A:A,COUNTA(A:A),1)
For strictly finding the last non-empty cell in a column, this should work...
=LOOKUP(2^99, A2:A)
What about this formula for getting the last value:
=index(G:G;max((G:G<>"")*row(G:G)))
And this would be a final formula for your original task:
=DAYS360(G10;index(G:G;max((G:G<>"")*row(G:G))))
Suppose that your initial date is in G10.
I went a different route. Since I know I'll be adding something into a row/column one by one, I find out the last row by first counting the fields that have data. I'll demonstrate this with a column:
=COUNT(A5:A34)
So, let's say that returned 21. A5 is 4 rows down, so I need to get the 21st position from the 4th row down. I can do this using inderect, like so:
=INDIRECT("A"&COUNT(A5:A34)+4)
It's finding the amount of rows with data, and returning me a number I'm using as an index modifier.
for a row:
=ARRAYFORMULA(INDIRECT("A"&MAX(IF(A:A<>"", ROW(A:A), ))))
for a column:
=ARRAYFORMULA(INDIRECT(ADDRESS(1, MAX(IF(1:1<>"", COLUMN(1:1), )), 4)))
This will give the contents of the last cell:
=indirect("A"&max(ARRAYFORMULA(row(a:a)*--(a:a<>""))))
This will give the address of the last cell:
="A"&max(ARRAYFORMULA(row(a:a)*--(a:a<>"")))
This will give the row of the last cell:
=max(ARRAYFORMULA(row(a:a)*--(a:a<>"")))
Maybe you'd prefer a script. This script is way shorter than the huge one posted above by someone else:
Go to script editor and save this script:
function getLastRow(range){
while(range.length>0 && range[range.length-1][0]=='') range.pop();
return range.length;
}
One this is done you just need to enter this in a cell:
=getLastRow(A:A)
Calculate the difference between latest date in column A with the date in cell A2.
=MAX(A2:A)-A2
To find last nonempty row number (allowing blanks between them) I used below to search column A.
=ArrayFormula(IFNA(match(2,1/(A:A<>""))))
The way an amateur does it is "=CONCATENATE("A",COUNTUNIQUE(A1:A9999))", where A1 is the first cell in the column, and A9999 is farther down that column than I ever expect to have any entries. This resultant A# can be used with the INDIRECT function as needed.
Ben Collins is a Google sheets guru, he has many tips on his site for free and also offers courses. He has a free article on dynamic range names and I have used this as the basis for many of my projects.
https://www.benlcollins.com/formula-examples/dynamic-named-ranges/
Disclaimer, I have nothing to gain by referring Ben's site.
Here is a screenshot of one of my projects using dynamic ranges:
Cell D3 has this formula which was shown above except this is as an array formula:
=ArrayFormula(MAX(IF(L2s!A2:A1009<>"",ROW(2:1011))))
Cell D4 has this formula:
="L2s!A2:E"&D3
This may work:
=DAYS360(A2,INDEX(A2:A,COUNTA(A2:A)))
To pick the last in a column of arbitrary, non-empty values ignoring the header cell (A1):
=INDEX(A2:A,COUNT(A2:A))
With the introduction of LAMBDA and REDUCE functions we can now compute the row number in a single pass through the cells (Several of the solutions above filter the range twice.) and without relying on magic text or numeric values.
=lambda(rng,
REDUCE(0, rng, lambda(maxrow, cell, if(isblank(cell),maxrow,row(cell)) ) )
)(A:A)
which can be nicely packaged into a Named Function for usage like
=LAST_ROWNUM(A:A)
It works on columns with interspersed blanks, and multi-column ranges (because REDUCE iterates over the range in row-first), and partial columns (like A20:A), still returning the actual row number (not the offset within the range).
This can then be combined with Index to return the value
=DAYS360(A2, Index(A1, LAST_ROWNUM(A:A)))
(In truth, though, I suspect that the OPs date values are monotonic (even if with blanks in between), and that he could get away with
=DAYS360(A2, MAX(A2:A))
This solution is identified above as relying on the dates being "contiguous" - whether that means "no blanks" or "no missing dates" I'm not certain - but either stipulation is not necessary.)
