On tab 1, I have a column where each cell in that column has a group of numbers, and another column where that group of numbers is associated with a name.
A1: 131,210,312,419,5010 B1: Jim A2: 210,311,517,614,701 B2: Tom A3: 51,120,210 B3: Sam A4: 311,701,1012 B4: Tim
On tab 2, I have a column of numbers.
A1: 131 A2: 210 A3: 120 A4: 42
Next to each number, I want to return the name associated with the first list which contains the number. So in this example, it should be…
A1: 131 B1: Jim A2: 210 B2: Jim A3: 120 B3: Sam A4: 42 B4: N/A
I’m thinking find or vlookup might be involved, but I haven’t been able to figure out how to make it come together.
In order to achieve a true match, you must enforce the condition that each value looked for will begin and end with a comma. This string concatenation together with the wildcards will necessitate an array formula.
The array formula in E1 is
=INDEX('Tab 1'!$B$1:$B$4,MATCH("*,"&D1&",*",","&'Tab 1'!$A$1:$A$4&",",0)). This requires Ctrl+Shift+Enter rather than simply Enter. Once entered correctly, it can be filled down as necessary. You may wish to apply an
IFERROR wrapper to show an empty string instead os
Entered as an array formula (Ctrl-Shift-Enter) and copied down, this works:
