Trim all cells within a workbook(VBA)

The Problem (Q-score 3, ranked #287th of 303 in the Excel VBA archive)

The scenario as originally posted in 2014

I have attempted to add functionality to an excel add-in ave been developing which trims the leading spaces at the end of used cells, and maybe even parse the text, The reason I need to do this is simply to have it turn into a hyperlink which I have already working but that parts fine.

This is what I have attempted so far, I have it trimming the active.worksheet am on which is fine but I can’t figure out how to:

1. Trim Every cell being used across the whole workbook.
2. And also parse the text if possible

This is my attempt at Trimming the entire workbook, Its something simple I just know it, I just cant figure it out:

Sub DoTrim(Wb As Workbook)
Dim cell As Range
Dim str As String
Dim nAscii As Integer
Dim wsh As Worksheet

For Each wsh In Worksheets
    With wsh.UsedRange
        For Each cell In ActiveSheet.UsedRange
            str = Trim(cell)
             If Len(str) > 0 Then
                        nAscii = Asc(Left(str, 1))
                        If nAscii < 33 Or nAscii = 160 Then
                            If Len(str) > 1 Then
                              str = Right(str, Len(str) - 1)
                            Else
                                str = ""
                            End If
                        End If
                    End If
                    cell = str
        Next cell
    End With
Next wsh
End Sub

Any advice would be welcome am fairly new to this Language so sorry if I sound like a complete Newb!

TL;DR Trims cells only worksheet am on, needs to run across whole workbook I cant figure out how to iterate it across the whole thing.

EDIT: Is that also a quicker way of trimming these cells, the spreadsheets that are created for whom am designing this are massive and takes a while to trim the cells at times

Why this Range / Worksheet targeting trips people up

The question centers on reaching a specific cell, range, or workbook object. In Excel VBA, this is the #1 source of failures after activation events: every property (.Value, .Formula, .Address) behaves differently depending on whether the parent Workbook is explicit or implicit.

Untested

Is this what you are trying?

Sub DoTrim(Wb As Workbook)
    Dim aCell As Range
    Dim wsh As Worksheet

    '~~> If you are using it in an Add-In, it is advisable 
    '~~> to keep the user posted :)
    Application.StatusBar = "Processing Worksheets... Please do not disturb..."
    DoEvents

    Application.ScreenUpdating = False

    For Each wsh In Wb.Worksheets
        With wsh
            Application.StatusBar = "Processing Worksheet " & _
                                    .Name & ". Please do not disturb..."
            DoEvents

            For Each aCell In .UsedRange
                If Not aCell.Value = "" And aCell.HasFormula = False Then
                    With aCell
                        .Value = Replace(.Value, Chr(160), "")
                        .Value = Application.WorksheetFunction.Clean(.Value)
                        .Value = Trim(.Value)
                    End With
                End If
            Next aCell
        End With
    Next wsh

    Application.ScreenUpdating = True
    Application.StatusBar = "Done"
End Sub

Loop-performance notes specific to this pattern

The loop in the answer iterates in process. On a 2026 Office build, setting Application.ScreenUpdating = False and Application.Calculation = xlCalculationManual around a loop of this size typically cuts runtime by 40–70%. Re-enable both in the Exit handler.

What changed between 2014 and 2026

The answer is 12 years old. The Excel VBA object model has been stable across Office 2013, 2016, 2019, 2021, 365, and 2024/2026 LTSC, so the pattern still compiles. Changes that might affect you: 64-bit API declarations (use PtrSafe), blocked macros in downloaded files (Mark-of-the-Web), and the shift toward Office Scripts for web-first workflows.
