Final answer:
To delete every third row in Excel, you can use a formula with the MOD and ROW functions to identify the rows to be deleted, and then remove them using the 'Delete' option. This can be done by following a step-by-step process involving selecting an empty column, entering a formula, sorting the data, and deleting the identified rows.
Step-by-step explanation:
To delete every third row in Excel, you can use a combination of the MOD and ROW functions in a formula. Here's how:
- Select an empty column next to your data.
- In the first cell of the empty column, enter the formula =MOD(ROW(),3).
- Drag the formula down to apply it to all the rows in the column.
- Now, select the entire range of data, including the column with the formula.
- Click on the 'Data' tab and then 'Sort & Filter'.
- Choose 'Custom Sort' and sort by the column with the formula.
- All the multiples of 3 (every third row) will be grouped together.
- Select the grouped rows, right-click, and choose 'Delete'.
By using this method, you can easily delete every third row in your Excel worksheet.
