I am sure someone can assist with this basic formula question but I am unable
to get it to work correctly.

I want to create a formula that will reference another sheet to do the
following:
Sheet 2
A1 = 210 B1=211.045645
A2 = 211 B2=212.098332
A3 = 212 B3=213.123123

Sheet 1
C1=210

Sheet D1 formula - (if value of c1 is < sheet 2 B1 return value in sheet2
A1)(if value is B1 but <b2 = A2 and so on and so forth) I want this formula
to continue looking up for the B value that is closest to my # in question
and return the value in the adjacent A column. I have approximately 250
individual comparison fields to look up so I am hoping to have a formula that
will accomplish this without being too cumbersome.

I appreciate it!!!

I have used the following functions to do what you are looking for:

MATCH(<Value,<Single Column or Single Row,<Match Type)

First argument is the value you are looking for

Second argument can only be either a single column or a single row that you
want the function to look within the range for that particular value.

Third argument is the type of match you are using

<Match Type = -1
List must be in ascending order and looks for the largest value that is
less than or equal to <Value

<Match Type = 0
Looks for <Value within the list, but if not found, function returns
"#NA!" error message

<Match Type = 1
List must be in descending order and looks for the smallest value that
is greater than or equal to <Value

Remark

This function returns the Nth spot in the list where it located the value at
if it is found. Therefore, if you have the second argument as B15:B84, and
it had found the <Value in B32, the MATCH function will return a value of
18.

ISERROR(<Criteria)

This is to trap for those items that returns an error message so as the
formula can keep doing what it needs to do.

If(<Criteria,<True,<False)

This is to help with the error trapping and not cause issues with other
formulas dependent on this cell.

ADDRESS(<Row,<Column,,,<SheetName)

This function returns the address by default in absolute reference with it
in A1 style.

INDIRECT(<AddressReference)

This returns the value that is within the Address Reference cell.

ROW(<AddressReference)

Returns the first row number within the address reference

COLUMN(<AddressReference)

Returns the first column number within the address reference

Now for an example of putting this all together.

If the list is within B5:B500 to look up on Sheet1 and the value is on cell
C5 on Sheet2, which you want to return such value in column A of Sheet1 into
cell D5 on Sheet2, then use the following formula:

=IF(ISERROR(MATCH($D5,Sheet1!$B$5:$B$500,-1)),"",INDIRECT(ADDRESS(MATCH($D5,Sheet1!$B$5:$B$5 00,-1)
+ ROW(Sheet1!$B$5:$B$500) - 1,COLUMN(Sheet1!A:A),,,"Sheet1")))

Why did I use the ROW() and COLUMN() functions instead of absolute numbers?

Simple. If you go to insert/delete rows/columns/cells, in most cases, the
formulas should be able to adjust themselves, but if we used absolute
numbers instead such as a "1" in place of "COLUMN(Sheet1!A:A), the formulas
will not adjust and that's where it can be rather time consuming and
overlooking can take place if there's enough of such formulas in place.

Hi,

You want to find the closest match to C1 on column A of sheet 2 and return
column B? Try this

=INDEX(Sheet2!B1:B100,MATCH(MIN(ABS(Sheet2!A1:A100-Sheet1!C1)),ABS(Sheet2!A1:A100-Sheet1!C1),0))

This is an array formula which must be entered with CTRL+Shift+Enter and NOT
'just enter. If you do it correctly then Excel will put curly brackets around
'the formula{}. You can't type these yourself. If you Edit the ranges
'then you must re-enter as An array

If you can organise our data like so


A1 = 210 B1 = 0
A2 = 211 B2 = 211.045645
A3 = 211 B3 = 212.098332

etc., you can use

=INDEX(Sheet2!A:A,MATCH(C1,Sheet2!B1:B50,TRUE))

OK - I tried both examples and can not get them to work. Let me provide the
actual sheet and field references since I tried plugging mine in and that
didn't work.

I am working on a sheet called xxx-xxxx, I am trying to input a formula in
M2 to evaluate K2. I would like the formula to search column B on
sheet1(there are up to 5 decimals and no whole numbers in each instance) -
once a cell in column b has been identified (i.e. K2 is B5 and less than B6
so I want to identify B5) I want to return the value adjacent to B5 (A5) on
sheet1 to M2.

Thank you for the previous responses but I guess their logic was over my
head or my understanding wasn't clear - thanks again!

Correction
once a cell in column b has been identified (i.e. K2 is B5 and less than B6
so I want to identify B5) I want to return the value adjacent to B5 (A5) on
xxx-xxxx to M2.
