My source file columns look like this.
Is there any condition based column update function that checks the 2 columns and updates the result as below
If it is acceptable for those rows where %Completion 1 & %Completion 2 are both either blanks or errors to return 0.00% in the result column rather than blank as in your example (and assuming that your source columns are in A1:Bx), you can try the following in C1:
={"RESULT";arrayformula(mmult(n(iferror(offset(A2:B,,,max(filter(row(A2:A),not(isblank(A2:A))),filter(row(B2:B),not(isblank(B2:B))))-1))),{1;1}))}
You will need to change the number format of column C to percentages using the toolbar.

In my Google Sheet, I have 1000+ rows of Date entries. For each Date, I am calculating the Month# and Week# using MONTH() and WEEKDAY() functions respectively.
Here is the link to a sample file: https://docs.google.com/spreadsheets/d/1Af5-pYMFWZ1QtLoaAbPZYMGRvk43JBslUp4KyOFADfA/edit?usp=sharing
Problem Statement:
For all rows which have a unique Month# and Week#, I would like to implement a formula and calculate Output. For example, in my sheet, rows 3 to 6 pertain to Month=1 and Week=4. For this set of 5 rows I am calculating Output column as the subtraction from the first element in that set (ie... C3-$C$3, C4-$C$3, C5-$C$3 so on ). Similarly row 7 to 10 pertain to Month=1 and Week=5, and so I calculate Output
as Data-$C$7 and so on.
How do I implement this structure to calculate Output column on each set of unique Month# and Week# values?
Delete everything from Column F (including the F2 header). Then place the following formula into cell F2:
=ArrayFormula({"Output";IF(C3:C="",,IFERROR(C3:C-VLOOKUP(E3:E,{E3:E,C3:C},2,FALSE)))})
This one formula will create the header and return results for all valid rows.
Since VLOOKUP always finds only the first matching instance of what it is looking up, we can use it to ask that each value in C3:C subtract that first instance of where week-number match for each row.
By the way, although you didn't ask about this, you can also use this type of array formula in Columns D and E, instead of all of the individual formulas you have. To do that, delete everything from Columns D and E (including the headers). Then...
Place the following formula in D2:
=ArrayFormula({"Month #";IF(B3:B="",,MONTH(B3:B))})
... and the following formula in E2:
=ArrayFormula({"Week #";IF(B3:B="",,WEEKNUM(B3:B))})
I'm setting up a spreadsheet that has specific columns summed in each row, but I need the formula to be included when a row is inserted.
The current formula also includes a statement to make a 0 value, if a check box is checked in the last column:
=IF(T2=FALSE, SUM(I2,K2,L2,M2,N2,O2), 0)
Is there a way I can do this using an array formula?
Here is a formula which will give a sum for columns I to O in each row, ignoring column J:
=ArrayFormula(if(I2:I="","",if(T2:T<>FALSE,0,I2:I+sumif(row(K2:O)+0*column(K2:O),row(K2:O),K2:O))))
but this assumes all rows that have data will have a number in column I.
If this isn't the case, you could go on to test columns individually like this:
=ArrayFormula(if((I2:I="")*(K2:K=""),"",if(T2:T<>FALSE,0,I2:I+sumif(row(K2:O)+0*column(K2:O),row(K2:O),K2:O))))
and so on up to column O if necessary, or maybe column T is always completed and you could test that - it depends how your data actually looks.
Note 1
row(K2:O)+0*column(K2:O)
is necessary to generate an array which is has the same dimensions as K2:O as required by SUMIF.
Note 2
There's also the MMULT approach to getting the row sums as demonstrated here
={"AAA"; ARRAYFORMULA(IF(LEN(T2:T), IF(T2:T=FALSE, I2:I+K2:K+L2:L+M2:M+N2:N+O2:O, 0), ))}
I have a spreadsheet that I want to calculate the average of the first three values in a row...
For example:
Column A Column B Column C Column D
Row 1 7/1/2017 6/1/2017 5/1/2017
Row 2 $934 $392 $214
So my formula is
=average($A$2:$C$2)
This works fine, until I add a new column to the left of Column A to add the newest month's data which now looks like this:
Column A Column B Column C Column D
Row 1 7/1/2017 6/1/2017 5/1/2017
Row 2 $934 $392 $214
The issue is that spreadsheet automatically changes the formula to
=average($B$2:$D$2)
when what I really want is to retain the original formula so it will continue to give the the average of the most recent three months of data.
Here is a link to a spreadsheet so you can see what is happening, sheet one is before added column, and sheet two is after adding column.

How can I do this? Thanks!
I suggest a sensible place to put such a formula is in ColumnA (having made room for it!) hence:
=average(OFFSET(A2,,1,1,3))
I have two columns I'd like to compare data in. The first column has about 50 rows, whereas the second column has 200 rows.
I would like to be able to tell if any cell in the first column matches up with a value in the second column.
I first tried this with the QUERY() function
=QUERY(A12:B, "Select A where A = B")
but this didn't seem to work, I got a circular dependency error.
I then tried the array function.
=ARRAYFORMULA(if(A12:A=B12:B,"REMOVE_ME", "DON'T REMOVE ME"))
but this was outputting incorrect values. Is there an easier way to do this or am I missing something?
Here is sample data: https://docs.google.com/spreadsheets/d/1IVUksDc79uJPfe6_Yfkp-EBelzh-U3q1EIiYlguQoRw/edit?usp=sharing
The value 6 is given MATCH because there is a value 6 somewhere in Column B.
Use this formula in C2:
=IFERROR(IF(VLOOKUP(A2,$B$2:$B$22,1,0)>0,"MATCH","NO MATCH"),"NO MATCH")
I am trying to use the INDEX() formula inside an ARRAYFORMULA(). As a simple (non-sense) example, with 4 elements in column A, I expected that the following array formula entered in B1 would display all four elements from A in column B:
=ARRAYFORMULA(INDEX($A$1:$A$4,ROW($A$1:$A$4)))
However, this only fills field B1 with a the value found in A1.
When I enter
=ARRAYFORMULA(ROW($A$1:$A$4))
in B1, then I do see all numbers 1 to 4 appear in column B. Why does my first array formula not expand similar like the second one does?
The INDEX function is one that does not support "iteration" over an array if an array is used as one of its arguments. There is no documentation of this that I know of; it simply is what it is. So the second argument will always default to the first element of the array, which is ROW(A1).
One clumsy workaround to achieve what you require relies on a second adjacent column existing next to the source data* (although it is unimportant what values are actually in that second column):
=ArrayFormula(HLOOKUP(IF(ROW($A$1:$A$4);$A$1);$A$1:$B$4;ROW($A$1:$A$4);0))
or indeed something like:
=ArrayFormula(HLOOKUP(IF({3;2;4;1};$A$1);$A$1:$B$4;{3;2;4;1};0))

* This is no longer a requirement in the newest version of Sheets; the second argument in the HLOOKUP can just be $A$1:$A$4.
Here is a tip for using vlookup with an array, so that even if the columns are moved later on the formula will still work correctly....
In general, configure the vlookup so that it's reading only 2 columns and returning the second. This can be done by inputting only the 2 columns required, rather than a range and column index.
Example:
Replace the following formula which would fail if columns are moved
=arrayformula( vlookup(C:C, booking!$A:$E ,5 ,false) )
with this formula which will continue to work even if columns are moved
=arrayformula( vlookup(C:C, {booking!$A:$A,booking!$E:$E} ,2 ,false) )
Note, you can also simulate the index function using vlookup.
Example:
Column R:R contains the row index numbers for looking up data in column booking!$A:$A
=arrayformula(vlookup(R:R ,arrayformula({row(booking!$A:$A), booking!$A:$A}),2 , false))
It's a nested array, so it can be helpful to test in stages, eg just the inner part for one example, eg return entry in row 10:
=vlookup(10 ,arrayformula({row(booking!$A:$A), booking!$A:$A}),2 , false)
