About This Feature

Overview

File Optimization is a built-in spreadsheet file cleanup feature in WPS Office for Windows. It is used to reduce file size, remove redundant content, and help improve the opening and editing experience for large spreadsheets.

Core tasks include:

Start File Optimization: open the feature from the Efficiency tab, then let it automatically analyze the current file and show its size.
Review optimized items and set automatic optimization: check items such as image compression, redundant data cleanup, and style cleanup, then decide whether to allow automatic optimization when a file meets the required conditions.

This feature is useful when a spreadsheet becomes large, opens slowly, contains many images, or has gone through repeated formatting changes.

Compare with Alternatives

Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	Provides a File Optimization entry directly inside spreadsheets, starts analysis automatically, and lists items such as image compression, redundant data cleanup, and style cleanup.	Excel provides official ways to reduce workbook size, including saving in binary format, compressing pictures, deleting unused worksheets, and controlling pivot cache data.	Google Sheets provides official spreadsheet performance guidance, such as removing unnecessary conditional formatting, reducing repeated calculations, and using helper columns to improve formulas.	Notion provides official database performance guidance, such as reducing complex filters and sorts, hiding unnecessary properties, and deleting unused pages.	Adobe Acrobat provides PDF optimization and compression tools that reduce PDF size, but they are not designed for spreadsheet files.
WPS Advantages	Advantage: WPS brings the optimization entry, optimized-item list, and automatic optimization setting together in the spreadsheet interface for the current file.	Compared with WPS: Excel relies more on separate manual methods across save format, pictures, and cache settings.	Compared with WPS: Google Sheets focuses more on performance guidance and does not present a centralized file optimization entry for the current spreadsheet file.	Compared with WPS: Notion focuses on database structure and load performance rather than a native spreadsheet file size reduction workflow.	Compared with WPS: Adobe focuses on PDF files rather than spreadsheet files.

Overall Conclusion
WPS File Optimization is a practical choice when you want to reduce the size of the current spreadsheet file from within the spreadsheet interface. Other products provide manual workbook reduction methods, performance guidance, or optimization for different file types, while WPS keeps the workflow focused on the current spreadsheet.
