我认为你必须学习 DOM 自动化才能干净地做到这一点。我查看了 ebay 页面上的 HTML,对于以前没有使用过 DOM 自动化的人来说可能有点过头了。我不打算写这篇文章,但听起来你有点紧张,所以你去吧。你可以用它来学习。请记住,这将在短期内起作用,但是当他们更改 HTML 时,它将失败。

如果您坚持使用现有代码,您还可以尝试在查询后删除查询表。
Dim QRY_TABLE As QueryTable
For Each QRY_TABLE In ThisWorkbook.Sheets(1).QueryTables
QRY_TABLE.Delete
Next
此方法不会删除电子表格上的查询表值,但会终止查询表连接。如果你有太多这些,它可能会导致崩溃。
最后一个建议,如果您的工作簿包含很多内容,vlookups
那么这可能是真正的罪魁祸首。祝你好运!
