Hi,

I have two worksheets - Sheet1 and Sheet2

Sheet 1
Col A Col B
Codes A/C Numbers
Pacific 145762
Atlantic 345782
Monte carlo 478562
Pacific 785


Sheet 2
Col A
Codes ( unique )
Pacific
Atlantic
Monte Carlo

I am using Excel 2007,
I need to match Sheet 2 Col A data with Sheet1 Col A data,
if any match found i need result in Col B of Sheet 2. If there are
more than one then
the A/C numbers to be separated by comma ( eg., 145762,785)

Sheet 1 has Approximately 1.5 Lakh Row

Sheet 2 has only 10,000 rows.

Please help me guys....
