How to Auto Number or Renumber after Filter in Excel: 7 Easy Ways

We will now walk you through 7 easy ways to auto fill number or renumber after Filter in Excel.

1. Using SUBTOTAL to Auto Number or Renumber after Filter in Excel

We can auto number rows using the SUBTOTAL function in Excel. To do so, instead of numbering the rows manually we will use this function to number rows.

2. Auto Number or Renumber after Filter by Combined Formula

We may not always have data in continuous cells. In this case, the data may have been sorted by department. We will use the IF function and the LEFT function first to ascertain whether the entries are of a person or not. Then we will use the SUBTOTAL function to determine the serial.

In this case, we will first determine whether the entries in the Name column are of persons or not. Notice that in the sheet, before the name of every department there are two spaces. So, any entry that is not a name will have two spaces on the left. Using this condition, we can determine whether the entry is the name of a person or not.

STEPS:

• To do so, in the F5 cell, we type,

• Pressing the Enter key we will get the result in the E5 cell.

• Now by dragging down (double-clicking won’t work as there are not always values in the contiguous cells) the Fill Handle to use the AutoFill formula of Excel, we will get values in corresponding cells.

After determining whether the name is of a person or not, we can easily number the Serial column. To do so, we type in the  B5 cell,

• Pressing the Enter key we will get the result in the B5 cell.

Now by dragging down or double-clicking the Fill Handle to use the AutoFill feature of Excel, we will get values in corresponding cells.

We may want to put serial from scratch in case of every department. In that case, we just have to change the moving range for each of the departments. For the Finance department, we will change the range to,

• Pressing the Enter key we will get the result in the B8 cell. Now by doing so for all the departments and dragging down the Fill Handle, we will get serial numbers starting from 1 for each of the departments.

3. Auto Number or Renumber after Filter Using AGGREGATE Function

The AGGREGATE function in Excel is used associating with different functions in Excel like AVERAGE, COUNT, MAX, MIN, SUM, PRODUCT, etc., with the option to ignore hidden rows and error values to get certain results. We can use this function to perform different operations. In this article, we will show how can we use the AGGREGATE function to number rows after filtering.

STEPS:

To do so, in cell B5 we type,

• Pressing the Enter key we will get the result in the B5 cell.

• Now by dragging down or double-clicking the Fill Handle to use the AutoFill feature of Excel, we will get values in corresponding cells.

• We can filter data using the steps shown in method 1. If we filter data and choose the Finance department, the resultant rows will be numbered automatically.

• Then we will select the entire Serial column.
  Put 1 in the first cell, in this case, cell B5.

Fill all the cells of the column using Fill Handle. By dragging down or double-clicking the Fill Handle to use the AutoFill feature of Excel we will get values in corresponding cells.

• After clicking the Fill Series, the correct order of serial will appear.

• We can filter data using the steps shown in method 1. If we filter data, and choose Finance department, the resultant rows will be numbered automatically.

7. Auto Number or Renumber after Filter Using VBA

We can use VBA code to the auto number or renumber after filtering in Excel.

STEPS:
To use the VBA editor,

• Open the Developer tab >> select Visual Basic

• A new window will open.

• Go to Insert and select Module.

• A new Module will open.

• Copy the code below and paste it into the Module.

Sub Autonumbering()
Dim X As Range
Dim Y As Range
On Error Resume Next
xTitleId = "Autonumbering"
Set Y = Application.Selection
Set Y = Application.InputBox("Range", xTitleId, Y.Address, Type:=8)
Set Y = Y.Columns(1).SpecialCells(xlCellTypeVisible)
xIndex = 1
For Each X In Y
X.Value = xIndex
xIndex = xIndex + 1
Next
End Sub

Here, we have initiated a Sub Procedure named Autonumbering. We have declared two variables X and Y. Both variables are Range type. We have used For Loop to go to the next cell.

Also use On Error Resume Next to continue while occurring any error.

To run the code from the Run tab select Run Sub/UserForm. Or you can also use the F5 key to run the code. A new dialogue box will appear. Type the range over which you want to put a correct serial number.

• You will get the correct serial in the Serial column.

We can filter data using the steps shown in method 1. If we filter data, and choose Finance department, the resultant rows will be numbered automatically.
