I'm trying to fill the last two columns according to a mapping table, using a VLOOKUP.
However I don't see the last column with Id as expected.
Why?
=VLOOKUP(C10:C,I28:K, {2,3}, FALSE)
I had to add "ArrayFormula"
Is there any way to read which formula requires the `Arrayformula" to expand?
=ARRAYFORMULA(VLOOKUP(C10,I28:K28, {2,3}, FALSE))

So I have two rows:
ID
TagDog
TagCat
TagChair
TagArm
Grouped Tags (need help with this)
1
TRUE
TRUE
TagDog,TagArm
Row 1 consists mainly of Tags, while rows 2+ are entries. This data ties ENTRIES to TAGS.
What I'm needing to do is concatenate/join the tag names per entry. For example, look at the last column above.
I suspect we could write a formula that would:
Create an array of non-empty cells in the row. (IE: [2,4])
Return it with the header row A (IE: [A2,A4])
Then join them together by a comma
But I am unsure how to write the formula, or if this is even the best approach.
Here's the formula:
={
"Grouped Tags (need help with this)";
ARRAYFORMULA(
REGEXREPLACE(TRIM(
TRANSPOSE(QUERY(TRANSPOSE(
IF(NOT(B2:E11),, B1:E1)
),, COLUMNS(B1:E1)))
), "\s+", ",")
)
}
The trick used is called vertical query smash. That's the part:
TRANSPOSE(QUERY(TRANSPOSE(...),, Nnumber_of_columns))
You can find a brief description of this one and his friends here.
I wasn't able to create a single formula that would do this for me, so instead, I utilized a formula inside of Sheets' Find/Replace tool, and it worked like a charm!
I did a find/replace, replacing all instances of TRUE with the following formula:
=INDIRECT(SUBSTITUTE(LEFT(ADDRESS(ROW(),COLUMN()),3),"$","")&"$1")
What this formula does is it finds the cell's letter, then gets the first row of the cell using INDIRECT.
Breaking down the formula:
ADDRESS(ROW(),COLUMN()) returns the direct reference: $H$1
LEFT("$H$1",3) returns $H$
SUBSTITUBE("$H$","$","") replaces the dollar signs ($) and returns H
INDIRECT(H&"$1") references the exact cell H$1
Now, I can replace all instances of TRUE with that formula and the magic happens!

Hopefully, that helps someone -- however, I would still be interested in seeing what the formula is for this solution.
The image explains what I would like to achieve probably the best:
The table I would like to create, at the moment I have only first three columns:
I would like the "New Volume" to have the same values whenever the keyword repeats. At the moment I have the three first columns but cannot figure out with what formula I can create the "New Volume" column.
I would appreciate the help.
This is a vlookup job.
=vlookup(D3;$D$3:$E$8;2;false)
It searches D column for identifier (also in column D) and returns value from second column. When vlookup is set as false, will always return first found value.
To avoid copying down the formula, you can nest it with arrayformula:
=ArrayFormula(ifna(vlookup(D3:D;$D$3:$E;2;false)))

I am would like to use the values in the name column (search key) and look them up in a table with the headers [name, regular, overtime].
The formula I am using is:
=ArrayFormula(index(rateTable, match(formName,workers,0),match(formType,rateTypes,0),0)*{formHours})
It works except the search key in the MATCH formula, does not reference every respective entry in the name column, but only works with one fixed reference to a cell.
Am I trying to use this formula beyond its capabilities? I'd like to know if I should stop searching. Thanks.
Here is a link to a copy of my sheet:
https://docs.google.com/spreadsheets/d/1sovuTB4zSTpl0RUHciYltr-pf8g4KPTgkYVE5lB4Ifk/edit?usp=sharing
=ArrayFormula(index(rateTable, match(formName,workers,0),match(formType,rateTypes,0),0)*{formHours})
for this task is best if you use VLOOKUP formula. paste in I2 cell:
=ARRAYFORMULA(IF(LEN(formName), IFERROR(VLOOKUP(formName, rateTable,
IFS(formType="Regular", 2,
formType="Overtime", 3), 0)) * formHours, ))

INDEX doesn't work with arrays as needed for ARRAYFORMULA. Either…
use copied formulas rather than a single ARRAYFORMULA, e.g.
=IF(NOT(LEN(A2)),"",index(rateTable, match(C2,workers,0),match(G2,rateTypes,0))*H2)
and drag-copy it down column I,
or refactor your INDEX(,MATCH( use to rely instead on VLOOKUPs and HLOOKUPs.
I've been at this problem for a while now. I am trying to sum numbers under a specific column when the rows equal a certain text and then display that sum on a different sheet. So far I came up with this formula: =IF(EXACT(A2,Table!A2:A)=TRUE,SUM(Table!C2:C)); however the only problem is that is sums everything in column C (which makes sense).
I wish there was a way to do something like the following: SUM(Table!C2:C where EXACT(A2,TABLE!A2:A)=TRUE). I've also tried the SUMIF(), DSUM(), and QUERY() functions to no avail. I must be getting logically tripped up somewhere.
Figured it out: =SUM(FILTER(Table!E4:E, EXACT(Table!A4:A,A4)=TRUE)).
=sum ( FILTER (b1:b10, a1:a10 = "Text" ) )
// the above formula will help you to take the sum of the values in column B when another column A contain a specific text.
The formula is applicable only in Google Spreadsheets
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)
