When a spreadsheet is full of screenshots, compressing images can become the most annoying part of the job. A workbook that should be easy to send can swell to roughly 30 MB, and doing one image at a time is not practical. The current WPS build only offers single-image compression, so it does not solve that problem.
Excel 2007 can compress all images in a workbook at once, but the version is far too old. Many simple tasks that WPS handles with one click require formulas or extra steps. Excel 2010 is newer, yet it still falls short in the same everyday areas.
Unofficial modified WPS builds are easy to find, but they raise security concerns. A better option came up in a group discussion: an official special edition called WPS Education Exam Edition. After testing it, the features needed for basic spreadsheet work were there.
What the Education Exam Edition is
Starting in March 2021, Level 1 and Level 2 WPS subjects began using a new WPS Office build designed for education exams. That is how the WPS Education Exam Edition became publicly available. It follows WPS's usual interface and comes with no ads.
The software runs smoothly and has no default advertising, which makes it reasonable for long-term personal use. It also includes some education-specific privileges: online templates and fonts can be used for free. Functionally, it is close to the standard edition.

It is intended for personal use only, not commercial use. If you need professional features, the standard paid version is the right choice, and buying it also supports the domestic software ecosystem.

The build is not a replacement for every professional workflow, but for personal spreadsheet work—especially when the main task is handling an image-heavy file without ads and without a subscription—it is a practical option worth testing.
