A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
True! we are not asking for a customization but we are looking for a workaround of what looks like a serious issue for Excel practitioners.
Once an excel file is created with the absolute path for PivotTableDataSource, it looks like it is damned forever, no matter what you change in advanced options. It is still not clear to me what triggers the absolute path, it looks like it happens only in excel files where I’ve lots of pivot.
However, if you go in Excel Options/Advanced Options/Save external link values and uncheck it, then you should be able to modify all PivotTableDataSource from absolute to relative. I’ve written some code to do this and apparently the excel files are ok after that, but I’ve not tested it extensively.
