Easy Way To Reduce Excel File Size Up To 20MB


Excel file size normally do not take to much space on our storage, usually the size is only some hundred of kilobytes or probably couple of megabytes. 

But in some cases the file size could be very enormous, in my experience it can be more than 20 MB, even though there is no any picture, diagram, chart, etc. in the file.

This enormous size make the file takes very long time to open, make the excel run very slow and quite hard to share by email.

Don't worry I already figured out why this happened and how to fix it, lets check together.

This file size problem probably caused by our bad habit in formatting excel. For example below, we wanted to fill color some cells but, we do block entire column. This action of course will add the excel file size since excel will record every cell formatting.

Opening and editing excel with different version of excel or other application also possibly causing this excel file size problem. But, don't worry, in this article you will find Easy Way To Reduce Excel File Size without installing any additional software.

How To Reduce Excel File Size

  1. Open the file with excel, but if the excel crash & failed to open the file you can try other application like WPS Office.
