Convert wind direction to degrees
I'm sure this is a simple problem but I'm stupid. I have a
column with wind direction (N,NNE,NE...) and I need to convert it to a numerical representation (0,22.5,45...). The spreadsheet has about 20,000 rows so I need to automate this. I have a mental picture how this needs to happen but I have no idea of the syntax necessary. Set a counter Read a cell If cell is empty quit Select Case statement Assign degree value to variable Write variable to adjacent cell Increment counter Do again Can anyone out there help me get started. I can get the select statements but I have no idea how to programatically read and write to cells. Thanks, Larry |

Your best bet is to set up the Wind Directions on a seperate sheet as follows: COL A COL B - - WindDir WindDeg N 0 NNE 22,5 NE 45 ENE 67.5 .... ... And then just use a Vlookup worksheet function to get the degrees - see funcion help if you are unfamiliar with vlookups.

wrote in : I read the function help but you didn't read the first line of my message. ;O} I've got what you indicated below on sheet2, a1:b16. I've got the wind dir in sheet1 column I. Column J is what I'm trying to populate. From what I can figure out I should have a cell somewhere on sheet1 with the following. =VLOOKUP(9,Sheet2!A1:B16,10,FALSE) That returns #N/A. What's up with that. I think I'm close but I just don't see it.

I hope you get this reply - it's been a while.
Assuming your column with wind direction on sheet1 (main data sheet) is column F then in the column where you want the numerical representation you need the formual =VLOOKUP(F1,$A$1:$B$16,2,0) You could replace the 0 at the end with false - it is the same thing.
