A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
AFAIK there is no way to get that path for sure.
You can loop through the Workbook.Connections collection to get a WorkbookConnection and if you found a query you can access it using the Workbook.Queries collection to get each WorkbookQuery, but none of these objects has a property to get the related path.
The reason is that a path can be dynamic, e.g. stored inside a parameter table, so you never know which file is used at runtime.
