Replacing Irrelevant Data with Meaningful Data
By now, most of the data cleaning process is complete. Finally, we notice that the Price per Unit column contains a few
na values that need to be replaced with meaningful data. To do this, follow these steps:

Step 1 Select the entire dataset.
Step 2 Click on Home Sort & Filter Filter to apply filters on all columns.

Step 3 Click on the filter arrow in the Price per Unit column.
Step 4 Uncheck all values except na.
Step 5 Click on the OK button.

All rows containing na will now be displayed. Suppose we want to replace these values with the minimum
value 10.
Step 6 Enter 10 in the first cell and using autofill, fill the remaining cells.
