If you paste a range from Excel as a linked object in PowerPoint (Paste Special > Paste As Link), and then open the same file in a copy of Office with a different display language and update the links, you will find that the specific range you pasted gets expanded to the entire used range of the spreadsheet.
- Create a spreadsheet in English with data in the range A1 to A5, and also in C20.
- Copy the A1 to A5 range.
- In PowerPoint, choose Paste Special, and then Paste As Link. Save the file.
- Open the file in PowerPoint with German as the display language. The linked object will display the range A1 to C20.
The range is stored in a language locale-specific format. When PowerPoint tries to retrieve the data range using the other language locale, and Excel doesn't understand it and returns the full used range in the spreadsheet.
