I have these two Excel files attached. One is a chart I saved out of PPT. The other is the content of that chart saved to a separate Excel file. The problem I am having is that the file size of the Chart file is much larger than the manually created Book1 file that I made with the content I wanted from the Chart file. I have a PPT file that has several several charts like this, so I am trying to clean the chart files in PPT of whatever is creating this extra space so that it will in turn reduce the size of my PPT file. I have already tried the embedded font steps and everything else suggested to reduce it (these charts must remain Excel editable too as opposed to pictures). So can someone tell me what is creating more size on the Chart file compared to the Book1 file and how to get rid of it? We are using Office 2013.
