Forgot to add in, I cant copy and paste and then filter 'uniq' coz the total data is more 68000, which is more than 65K rows per sheet.
If can i need help of using the IF(...) command..
thanks.. :-)

Without going into a lot of details, there are several ways to combine specific data from numerous sources of RAW DATA. The easiest way (once you understand how) would be to use Microsoft Access. Here you will need to use the 'help options' for the specific process; but what your will be doing is "mapping" two or more documents together which share 1 categories of redundant information (i.e. NAME, PART NUMBER, etc.).

For example, if each worksheet has a persons NAME, along with another columns or information. you would map the NAME in each worksheet, then select the additional fields you want captured in your output. Besides the Access Help engine, you can repost your help request here under 'mapping & Linking).






If you want to stay in Excel, try using a Index Match statement.

=INDEX(SheetA!C:C,(MATCH($A2,SheetA!A:A,0)))


Type this formula in a blank cell within the row/entry you are comparing. This formula will look in SheetA through all data within column A. If data is matched to the identifier ($A2), it will then copy the data entered in column C (number or text). #N/A is reported if no match is found.

SheetA

Part1 $2 A xxx
Part2 $3 B yyy
Part2 $4 V zzz

Sheet B

Part1 50 MN type your formula
Part2 60 WI type your formula
Part2 70 MO type your formula

The cell with the formula will collect "A","B" and ,'V" from the first sheet.
Copy and change the formula to collect data from which columns you want (skip the redundant/superfluous ones).

For best results, lock in your �identifier� cell (in this case $A2)




To utilize a formula solution, data within sheets needs to be organized the same way because you are defining which 'columns' to match and pull information from.
