Excel - How to count repeated values using VBA

In VBA (Visual Basic for Applications), you can count repeated values in Excel using a macro. Below is a simple example of how you can achieve this:

Sub CountDuplicates() Dim lastRow As Long Dim rng As Range Dim cell As Range Dim dict As Object ' Create a dictionary object to store unique values and their counts Set dict = CreateObject("Scripting.Dictionary") ' Find the last row in column A with data lastRow = Cells(Rows.Count, "A").End(xlUp).Row ' Loop through each cell in column A and count duplicates For Each cell In Range("A1:A" & lastRow) If cell.Value <> "" Then If dict.exists(cell.Value) Then ' Increment count if value already exists in dictionary dict(cell.Value) = dict(cell.Value) + 1 Else ' Add value to dictionary if it doesn't exist dict.Add cell.Value, 1 End If End If Next cell ' Display the counts in column B starting from B1 Range("B1").Resize(dict.Count, 1).Value = Application.Transpose(dict.keys) Range("C1").Resize(dict.Count, 1).Value = Application.Transpose(dict.items) End Sub

Here's what the code does:

  1. It initializes variables, including a dictionary object (dict) to store unique values and their counts.

  2. It finds the last row in column A with data.

  3. It loops through each cell in column A and counts the duplicates using the dictionary object.

  4. It displays the counts in column B starting from cell B1.

To use this macro:

  1. Press Alt + F11 to open the Visual Basic for Applications (VBA) editor.
  2. Go to Insert > Module to insert a new module.
  3. Copy and paste the above code into the module window.
  4. Close the VBA editor.
  5. Run the macro by pressing Alt + F8, selecting "CountDuplicates" from the list, and clicking "Run".

After running the macro, you'll see the counts of repeated values in column B, starting from cell B1. Adjust the code as needed to fit your specific requirements.
