Lookup function


Posted by Mike Wortman on July 20, 2001 4:41 AM

I'm trying to accomplish a very simple task and don't know the appropriate function to use. Here's what I want to do:

I want Excel to recognize a "work shift" on a schedule and return a value that represents the # of hours worked on that shift.
For example: the text string "7-6" would return a value of 11 (for an 11hr shift), "7-11" returns a value of 4, "12-8" a value of 7.5, etc.
I can accomplish it using IF,THEN statements but the formulas become very long because I have a lot of different shifts - so I thought a "lookup" table might be a more elegant solution. I have no experience with this funtion and cannot get it to consistently return the correct value. Maybe I should use MATCH or INDEX?
Here's the table I made:
shift hours
"7-11" 4
"7-3" 7.5
"6-2" 7.5
"11-7" 7.5
"12-8" 7.5
"7-6" 11
"4-8" 4
I want a formula that returns the value in th right column from the text string in the left column.

Help!

Do they need to be text strings??

Hi, would not the easiest answer be to have 2 columns IN and OUT in time format them column C: to be =b:-a:

If you want you can e.mail me an e.g.

Mike,

Assuming that the table is in the range A2:B8, the following should what you want:

=VLOOKUP(E1,$A$2:$B$8,2,0)

where E1 contains the lookup value, that is, the shift you're interested in.

Ian,

I don't think that should matter.

Aladin,
That worked perfectly, exactly what I wanted to do. You're a prince (or princess)! Whatever.
Thanx.

Aladin!

As i explained in my reply, it would be easier to calculate time values than test each one for conditions based on text.
And could "7-11" used in the original question not also be a 16hr shift.

Data Issue

Ian -- I took your reply as saying that VLOOKUP would not work with such text values, an unfortunate conclusion.
