Excel工作簿大小相当大

我有一个非常大的工作簿(大约30 MB)。我意识到这与一些相比相当小,但数学似乎并没有加起来。

  • 总共有19张,我有大约15-20个命名范围。

  • 除了其中四张外,其他所有纸张的使用范围都很小(100行和25列以下)

  • 四个中的两个是表(最小格式)约。 35,000行乘40列,包括从单独文件中粘贴的数据,总计大约。 20 MB。

  • 其他工作表不是表格,没有格式化,约9,000行100列和11,000行乘5列。

所以我的问题是:额外的10 MB来自哪里?

编辑:

请注意,我已经将每张纸的使用范围缩小到最低限度。此外,工作簿是从具有重要VBA的公司模板中复制的,但该文件小于1 MB。

当您将不同文件中的数据复制到一个文件时,通常会出现此问题,因为Excel无法正确管理最后一行和最后一列数字,因此请使用大量数据来存储空单元格的值。

请尝试以下操作。

第一次尝试

使用以下Excel Diet VBA脚本重置最大列号和行号。

Attribute VB_Name = "Module1"
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

第二次尝试

将所有数据复制到一个全新的文件并保存。
