Did you know?

Excel is an amazing tool for analyzing and visualizing  data sets. But data is not the only reason behind the large size of your excel file. There are many more things you need consider if you want to reduce the file size of your Excel file
Another reason for Excel to have an unreasonable file size is due to media, especially Images. Although you may think cropping and Image and resizing reduce its size, in fact Excel still keeps the entire image in memory. Hence the only way to free Image memory is to Compress Pictures
Now we used the compression feature, provided by Excel. The result: Our originally 829 KB picture was already reduced to 329 KB by just inserting it. The compression further reduced the size to 103 KB
