The SpreadsheetML format has built-in reserved names. When such a name is defined in the scope of a worksheet, a SpreadsheetNameException is thrown during parsing the document.

The WorkbookContentChanged event is invoked right after importing a document. 

If you set, for example, two copies, the printed copies will be 4. If you select three copies, the result will be nine copies.

The problem is that the spreadsheet wants to identify the main window. The main window is not known to the plugin and should not be, because it is located in a different app domain due to the specifics of the architecture (https://docs.microsoft.com/en-us/archive/msdn-magazine/2014/january/wpf-build-fault-tolerant-composite-applications).

There are four positions - High, Low, NextTo and None.

Setting up a paper size to A1 and exporting it actually sets the paperSize to 1. Using the same scenario in Excel sets the paperSize to 305.

This leads to inappropriate values when entering the Page Setup options later in Excel.

When a cell that has a defined name is selected, the associated name should appear in the name box. However, when the cell is part of a merged range, its row and column name (A1) is shown instead of the defined name.
