Tableau to Power BI starts from the workbook you already have. BIEscape builds a Power BI project (.pbip) you open in Power BI Desktop: visuals, a conversion status for each sheet, and live database connections that stay live. It is not a .pbix, not a pixel copy of the Tableau dashboard, and items that only convert in part stay marked partial.
Hyper → Excel uses the desktop converter. Clone the repo at https://github.com/lukashalim/scapeTableau.
