When working in Excel, it’s not uncommon to find yourself needing to extract every nth row of data from a dataset. Whether you’re analyzing survey results, creating reports, or preparing data for further analysis, mastering this technique can save you significant time and streamline your workflow. In this guide, we’ll explore seven simple yet effective methods to select every nth row in Excel. Let’s dive into these techniques!
1. Using Helper Columns
One of the simplest ways to select every nth row is by creating a helper column that generates a sequence of numbers. Here’s how:
- Insert a new column next to your data.
- In the first cell of the new column, enter the formula
=MOD(ROW(), n)
(replacen
with the number you want to use). - Drag the fill handle down to apply the formula to other cells in the column.
- Use filter to select the rows where the helper column equals 0.
Example:
If you want to select every 3rd row, your formula will be =MOD(ROW(), 3)
. After applying the filter, you’ll see rows 3, 6, 9, etc.

2. Using Excel Tables
Excel Tables not only organize your data, but they also provide structured references that simplify selecting every nth row. Here's how:
- Convert your data range into a table by selecting the data and going to Insert > Table.
- With the table selected, use the formula
=INDEX(table_range, n, 1)
to get every nth row. - Replace
n
with the multiple of the row you want to select.
Example:
To find every 4th row in your table, use =INDEX(Table1, 4, 1)
, which will return the 4th row's data.
3. Filtering by Row Number
You can also filter rows based on the row number. Here’s a straightforward way to do it:
- Select your dataset.
- Go to Data > Filter.
- In the filter dropdown, use a formula to define which rows you want to see based on their row number.
Example:
Filter by using a custom number filter to select rows that have a row number divisible by n.

4. Using Conditional Formatting
While primarily for visual representation, conditional formatting can help highlight every nth row for easy selection:
- Select your dataset.
- Go to Home > Conditional Formatting > New Rule.
- Choose Use a formula to determine which cells to format and enter
=MOD(ROW(), n) = 0
. - Set the formatting style and click OK.
This highlights every nth row, making it easy to spot when reviewing.
Example:
Setting n
to 5 will highlight rows 5, 10, 15, etc.
5. Advanced Filter Options
Excel’s Advanced Filter can be a powerful tool to select specific rows based on criteria:
- Create criteria that specify every nth row. You can create a small table with a formula to determine which rows to include.
- Go to Data > Advanced Filter.
- Set the list range to your data and the criteria range to your criteria table.
- Apply the filter to see the results.
Example:
If your criteria table includes a formula generating true/false values for every nth row, the advanced filter will use this to display only those rows.

6. VBA Macro
For those comfortable with coding, a VBA macro can automate selecting every nth row:
Sub SelectEveryNthRow()
Dim n As Integer
Dim i As Integer
Dim LastRow As Integer
n = 3 ' Replace 3 with your desired nth value
LastRow = Cells(Rows.Count, 1).End(xlUp).Row
For i = 1 To LastRow Step n
Rows(i).Select
Next i
End Sub
- Press
ALT + F11
to open the VBA editor. - Insert a new module and paste the code.
- Modify
n
to your desired value and run the macro.
This method is particularly useful for large datasets or repeated tasks.
7. Power Query
Power Query is another advanced option for selecting rows. Here’s how to use it:
- Load your data into Power Query.
- Add an index column by going to Add Column > Index Column.
- Filter the index to select only the rows you want based on the nth interval.
Example:
If you added an index column and set the filter to show every 5th index number, you’d select the 5th, 10th, 15th rows, etc.
