vlookup date or date

[jtodd]

HI

What I am trying to do is a lookup using 3 dates.

Date	Part
1/8/18	2287
2/8/18	2269
3/8/18	2234

<colgroup><col style="mso-width-source:userset;mso-width-alt:2596;width:53pt" width="71"> <col style="mso-width-source:userset;mso-width-alt:2925;width:60pt" width="80"> </colgroup><tbody>
</tbody>

Vlookup 2269 if it occurs on date 1 date 2 or date 3 ,
some thing like vlookup(2269,date1,2) or vlookup(2269,date2,2) or vlookup(2269,date3,2)

Hope this makes sense

=INDEX(A$2:A$4,MATCH(C1,B$2:B$4,0),1)

where C1 is your part number.

This assumes part numbers will be unique in column B which is what your data implies

Hi , sorry I did not explain myselft very well,
What I need is the lookup to look at the date and look at another table and lookup the date or the date before or the date after.

A		B
Date	Part		Date	Part
1/8/18	2842		31/7/18	2842
1/8/18	2287		31/7/18	2287
1/8/18	2320		31/7/18	2320
1/8/18	2842		31/7/18	2842
1/8/18	2355		31/7/18	2355

<colgroup><col span="5"></colgroup><tbody>
</tbody>

IE lookup 2320 in table A and find it in table B even though the date is the date before (might be the date after but only one)

My answer still stands, use INDEX(...MATCH()) on both tables, that will give you the dates from both tables.
Though you havent said what you want to do with them so that part's down to you.

+1, you are using reverse vlookup, index will return the date from TableB. Date in TableA is irrelevant.

=(INDEX($C$2:$C$6,MATCH(B2,$D$2:$D$6,0),1))

return date from col 3 - C, for each entry in col 2
I am assuming this will go to col 5 - E

Perhaps best would be to have these two tables separated
A-date
B-part
C-result from tableB
