Description:

This will try to reduce the size of the Excel file by forcing Excel to recalculate the used range for each sheet. 

Discussion:

You may have a workbook that has recently increased drastically in size. Usually this is caused by Excel thinking that the used range for one or more sheets is much larger than it should be. This code will delete all unused rows and columns and may significantly reduce the size of the Excel file. 

Code:

instructions for use

			

Option Explicit Sub ExcelDiet() Dim j As Long Dim k As Long Dim LastRow As Long Dim LastCol As Long Dim ColFormula As Range Dim RowFormula As Range Dim ColValue As Range Dim RowValue As Range Dim Shp As Shape Dim ws As Worksheet Application.ScreenUpdating = False Application.DisplayAlerts = False On Error Resume Next For Each ws In Worksheets With ws 'Find the last used cell with a formula and value 'Search by Columns and Rows On Error Resume Next Set ColFormula = .Cells.Find(What:="*", After:=Range("A1"), LookIn:=xlFormulas, _ LookAt:=xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlPrevious) Set ColValue = .Cells.Find(What:="*", After:=Range("A1"), LookIn:=xlValues, _ LookAt:=xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlPrevious) Set RowFormula = .Cells.Find(What:="*", After:=Range("A1"), LookIn:=xlFormulas, _ LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlPrevious) Set RowValue = .Cells.Find(What:="*", After:=Range("A1"), LookIn:=xlValues, _ LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlPrevious) On Error Goto 0 'Determine the last column If ColFormula Is Nothing Then LastCol = 0 Else LastCol = ColFormula.Column End If If Not ColValue Is Nothing Then LastCol = Application.WorksheetFunction.Max(LastCol, ColValue.Column) End If 'Determine the last row If RowFormula Is Nothing Then LastRow = 0 Else LastRow = RowFormula.Row End If If Not RowValue Is Nothing Then LastRow = Application.WorksheetFunction.Max(LastRow, RowValue.Row) End If 'Determine if any shapes are beyond the last row and last column For Each Shp In .Shapes j = 0 k = 0 On Error Resume Next j = Shp.TopLeftCell.Row k = Shp.TopLeftCell.Column On Error Goto 0 If j > 0 And k > 0 Then Do Until .Cells(j, k).Top > Shp.Top + Shp.Height j = j + 1 Loop If j > LastRow Then LastRow = j End If Do Until .Cells(j, k).Left > Shp.Left + Shp.Width k = k + 1 Loop If k > LastCol Then LastCol = k End If End If Next .Range(.Cells(1, LastCol + 1), .Cells(.Rows.Count, .Columns.Count)).EntireColumn.Delete .Range("A" & LastRow + 1 & ":A" & .Rows.Count).EntireRow.Delete End With Next Application.ScreenUpdating = True Application.DisplayAlerts = True End Sub
