Compare with Alternatives

Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	CHIINV can be entered directly in spreadsheet cells in WPS Spreadsheet, with syntax prompts, cross-sheet references, nested formulas, and automatic recalculation.	Microsoft Word supports formulas in table cells and can update formula results, but the workflow is centered on document tables rather than a full spreadsheet function workspace.	Google Sheets provides online collaborative spreadsheets with formula support for calculations, analysis, and data handling.	Notion formulas work with database properties, built-ins, and functions, mainly for database logic and property-level calculations.	Adobe Acrobat supports calculated PDF form fields for totals and field interactions, rather than a general spreadsheet formula environment.
WPS Advantages	Advantage: Direct cell-based spreadsheet formula entry fits everyday statistical work in WPS Office. Distinct: Syntax guidance appears while entering the function, which helps users complete formulas faster.	Compared with WPS: Formula support is available, but it is tied to Word table tools and is more suitable for document-table calculations.	Compared with WPS: Google Sheets emphasizes cloud collaboration and AI-assisted analysis, while WPS keeps a desktop spreadsheet workflow that is closer to traditional local office use.	Compared with WPS: Notion is better suited to database property logic than worksheet-cell formula editing.	Compared with WPS: Acrobat is better suited to PDF form calculations and field workflows, not spreadsheet-style function editing.

Overall Conclusion

If your main task is entering statistical formulas in spreadsheet cells, checking syntax quickly, and recalculating results when data changes, WPS offers a workflow that fits everyday spreadsheet use well. The other products also provide calculation features, but they are more focused on document tables, cloud collaboration, database properties, or PDF forms.
