Depending on your environment and audience (eg, an internal document in your company), Office IRM can prevent the document from being copied and even copied using print-screen.
Personally, I see these attempts as naive at best - the data can be easily copied anyway (for example by taking a photo of the screen), but it sends the right message to your colleagues.

If your excel file is accessible by anyone, then you can't.

You can only shrink the images to low resolution or putting watermark on it.

You can't.

Of course, there are certain measures you could employ, but there are always ways around them. You could (somehow) disable copy & paste within Excel, but then the user could take a screenshot (Alt-PrtScn) and crop it in an image editor.

If you somehow disable the ability to take a screenshot, they may feed the monitor output of their machine to another machine with a screen grabber, and get the image that way.

Or, of course, accepting the loss of quality, they could point a camera at their screen and get it that way.
