Excel工作簿的大小相当大

我有一个很大的工作簿（大约30 MB）。我意识到这与一些人相比是相当小的，但数学似乎不符合要求

• 总共有19张，我有大约15-20个命名范围

• 除四张外，所有这些图纸的使用范围都很小（小于100行25列）

• 四个表中的两个表（最小格式）约为35000行40列，由数据粘贴组成，数据粘贴值来自单独的文件，总计约20 MB

• 其他图纸不是表格，也没有格式化，大约9000行100列，11000行5列

所以我的问题是：额外的10MB来自哪里

请注意，我已经将每张纸上的使用范围减少到最低限度。此外，工作簿是从公司模板复制的，带有重要的VBA，但该文件小于1MB。

当您将不同文件中的数据复制到一个文件中时，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的编号，因此使用大量数据存储空单元格的值

尝试以下方法

使用以下Excel Diet VBA脚本重置最大列数和行号

您有数据透视表吗？没有-没有数据透视表所以除了两张表，您有15*（100*25）+9000*100+11000*5个单元格，可能与公式或其他内容一起使用。这只是少了一百万个单元，所以你的“丢失”10MB平均每个单元只能允许10字节，这对我来说似乎是合理的。我没有这样想。对我来说有道理。谢谢。你有数据透视表吗？没有-没有数据透视表所以除了两张表，你有15*（100*25）+9000*100+11000*5个单元格在使用，可能是公式之类的。这只是少了一百万个单元，所以你的“丢失”10MB平均每个单元只能允许10字节，这对我来说似乎是合理的。我没有这样想。对我来说有道理。谢谢
