Convert multiple page Power BI report into an excel

Hi , Hoping 

According to your description, you want to create a slicer and export all the pages to excel not csv.

Depending on your needs, currently Power BI Service export only supports single visuals to Excel.

For this , you can refer to this document:
Export data from a Power BI visualization - Power BI | Microsoft Learn

But you want to achieve the export of all pages, and only the shreet in Excel.

You can try to use the paginated report feature if it can meet your need. For more information, you can refer to :
Export Power BI paginated report to Microsoft Excel (Power BI Report Builder) - Power BI | Microsoft Learn

What are paginated reports in Power BI? - Power BI | Microsoft Learn

Bu another , you can also create the report in Excel using the "Analyze in Excel" feature.

For more information, you can refer to :
Create Excel workbooks with refreshable Power BI data - Power BI | Microsoft Learn

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI! 

Best Regards,

Aniya Zhang
