导出数据连接查询从Excel到CSV(> 2M行)

发布于 2025-02-12 05:36:53 字数 281 浏览 0 评论 0原文

我有一个电子表格,该电子表格正在数据连接中使用电源查询来在具有超过2M行的CSV文件上执行建模。 这很好,我可以根据需要对此数据进行分析。

但是,现在我想在制作所有操作后导出产生的数据。 我看不到在不输出表格的情况下导出数据查询结果的方法……我不能...因为行计数为1m。

  1. 我可以在不输出纸/多张纸的情况下导出数据吗?
  2. 如果是这样,我需要什么工具(如果有),一般步骤是什么?

我一直在尝试自己工作几个月,但是我必须认识到自己的局限性并寻求帮助。 非常感谢。 DD

I have a spreadsheet that is using power query in a data connection to execute modelling on CSV files that have more than 2M rows.
This works fine and I can run analysis on this data as needed.

However, now I want to export the resulting data after all the manipulations have been made.
I can't see a way to export the data query result without outputing to a sheet... which I can't... because the row count is >1M.

  1. Can I export the data without outputting to a sheet/multiple sheets?
  2. If so, what tool would I need (if any) and what are the general steps?

I've been trying to work this out on my own for months but I have to recognise my limitations and ask for help now.
Many thanks in advance.

您需要使用DAX Studio(Free)等外部工具连接到Power Pivot数据模型并将表导出到CSV。

如上所述,DAX Studio将输出数据模型的结果。
步骤如下:

  1. 下载并安装Excel的DAX Studio插件,
  2. 请确保您要提取的连接在数据模型中。
  3. 启动DAX Studio。
  4. !DAX Studio只有从Excel的“附加”选项卡启动时只能阅读您的数据。这是唯一取决于DAX Studio启动方式的数据源类型。同样,您必须从包含查询/连接的Excel文档的Addins菜单启动此信息。
  5. 将出现一个对话框。它应将数据源显示为无线电选择。如果将其弄清楚,则意味着您尚未将查询/连接添加到数据模型中。
  6. 选择“连接”。现在,您将在左侧看到数据模型中的所有表,现在可能会提取到CSV。

As David mentioned above, Dax Studio will output the results of the data model.
Steps as follows:

  1. Download and install the Dax Studio plugin for excel
  2. Make sure the connection you are trying to extract is in the data model.
  3. Launch Dax Studio.
  4. !!!Dax Studio will only be able to read your data if you launch it from the Add-ins tab of Excel. This is the only data source type where access to the data is dependent on how Dax Studio is launched. Again, YOU MUST LAUNCH THIS FROM THE ADDINS MENU OF THE EXCEL DOCUMENT CONTAINING YOUR QUERY/CONNECTION.
  5. A dialogue box will appear. It should show data source "Power Pivot Model" as the radio selection. If it is greyed out, it means that you have not added your query/connection to the data model.
  6. Select "Connect". You will now see all the tables in your data model on the left hand side and may now extract to csv.
