How to check or find if value exists in another column?
Supposing, I have two columns of data which contains some duplicate values in these both columns as left screenshot shown. And now, I want to find if the values in Column A also exists in Column C. To compare them one by one is not a good method, here, I can talk about some handy tricks for solving this problem in Excel.

To check if the values are in another column in Excel, you can apply the following formula to deal with this job.
1. First, you can copy the two columns of data and paste them into column A and Column C separately in a new worksheet, leave Column B blank to put the following formula.
2. Enter this formula: =IF(ISERROR(VLOOKUP(A4,$C$4:$C$14, 1, FALSE)),"Not Exist","Exist" ) into cell B2, and press Enter key, see screenshot:
Note: in the above formula, A4 is the cell of the first column that you want to check if it is in another column, and $C$4:$C$14 is the column that you want to be compared with.
3. Then select cell B4, and drag the fill handle over to the cells that you need to apply this formula, you will get the following result, Exist stands for the value in List A exists in List B as well, and Not Exist indicates the value is not in List B.
In Excel, you can also highlight the duplicate values in one column when they found in another column by using the Conditional Formatting. Please do as this:
1. Select the cells in List A that you want to highlight the cells where the values exit in List B as well.
2. Then click Home > Conditional Formatting > New Rule, in the New Formatting Rule dialog box, please click Use a formula to determine which cells to format from the Select a Rule Type section, and then enter this formula =MATCH(A4,$C$4:$C$14,0) into the Format values where this formula is true text box, see screenshot:
3. Then click Format button to go to the Format Cells dialog box, and choose one color you like under the Fill tab, see screenshot:
4. Then click OK > OK to close the dialogs, and now, you can see the values both in List A and in List B are highlighted from List A, see screenshot:
