A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Creating a new instance is unfortunately the only way (apparently) to get this to work in Excel 2013/16 right now.
If opening a new instance via ALT is problematic, maybe you'll wish to try this:
- Find your excel.exe binary.
- Copy and create a symbolic link in a convenient place (i.e. usually your desktop)
- Open properties of your symbolic link
- In the line for your link's target add ' /x' after the ...\excel.exe" (i.e. ...\excel.exe" /x)
Now every time you start Excel with that symlink, it will open a new instance.
Unfortunately those have their separate issues, especially when it comes to copy&paste...
