1) Compare Table 1 with Table 2
2) wherever the value in table 2 is not matching with Table 1 it should be coloured out and rectified to correct one as given in table 1.
3) Ensure All the parameter in Row1 of table 2 should be compared with all parameter in Row 1 of Table 1 so that required value is updated.

Please find attached my file. Table 1 is my main, table 2 is my table with incorrect entries, In table 3 I want correct entries to be filled. I want to tally all columns of my table to be verified to retrieve the correct information.

Just copy table1 to table3.....

Situation is

1) Table 1 is downloaded from internet

2) Table 2 is a manual entry wherein chances are infinity to do typing mistake.

3) My intent is to correct this typing error. And in order to do so my logic is to compare each row/cell of table 2 with table 1 and wherever there is typo against the value it should be rectified.

4) We could use Code as primary key, but there could be typing mistake in code entry also. So not sure how to handle this situation and where I need code to rectify the typing mistake at any row.

I am collating a information where I am copying information from the internet which is a manual entry. In Table 2,I have just shown some of the columns from my main data.

I just want my table 2 where I am making typo errors should be rectified based on Table 1(as reference). Does this convey what my problem area is or you think I am not able to frame my query correctly?

Can anyone help with the solution please?
