2. From the Google Apps, click on the Sheets icon and select the existing Sheet. 3. Enter the dataset you want to compare in two columns. Locate another empty cell that will hold the results of the comparison.

4. Type this formula on the selected cell, =ARRAYFORMULA (

5. Next, add the COUNTIF function. That is, =ARRAYFORMULA (COUNTIF(

6. Select the first column that contains the first list. That is =ARRAYFORMULA (COUNTIF(A1:A4

7. Next, select the next column. That is =ARRAYFORMULA (COUNTIF(A1:A4, B1:B4)) 8. Finally, hit the Enter Button

NOTE: If the formula returns 1, that means the dataset match. If otherwise, (0) indicates the dataset does not match. ### b) Using the Conditional formatting tool

2. Ensure your data is in two columns. 3. Then, create a separate column containing the comparison’s feedback. 4. On the feedback column, click on the first blank cell and enter this formula.
=IF(COUNTIF(\$B:\$B, \$A2)=0, “No match found”) 5. The formula returns zero if no match is found. Therefore, it can be used to check the difference between the data in the column in question.

Drag the formula to other cells and check the difference between the columns.

### b) Using Conditional Formatting

Steps:
