compare 2 sheets and extract only new rows
Can someone help me please? I have two sheets, one with last months
data and one with this months new data. I need to find a way to compare the two and extract only the rows from the second sheet that do not have a matching part number entry in the first sheet. Any help and advice would be greatly appreciated. |

compare 2 sheets and extract only new rows
John,
Can't discern your skill level - if you know VBA I suspect you would not find this a hard problem. I will give you the outlines of a VBA solution. I would create 2 Dictionary objects, one for each sheet, and I would use the part number for the key and Integer arrays for the values. I would put the number of the row that referenced the part number into the array. When finished processing both sheets, I would examine the arrays in the two Dictionary objects for each part number and do whatever you wish if the arrays are not identical.

Hi John,
I know you posted in programming, but here is a formula solution I believe will do what you want. =IF(COUNTIF(Sheet1!$A$1:$A$6,Sheet2!A1)=0,Sheet2!A 1,"") Where "Sheet1!$A$1:$A$6" is the old list (sheet1) Where "Sheet2!A1" is the beginning of the new list (sheet2) Pull formula down as far as the longest list goes. This should return values from the new list that are NOT on the old list. Copy and paste special values to a new column to get rid of formulas. Select all in new column and sort to get rid of empty cells. HTH Regards, Howard "John" wrote in message oups.com... Can someone help me please?
