Capability Summary	In WPS Spreadsheets, you can enter `=IMTAN(` in a worksheet cell and use formula prompts, nested calculations, and automatic recalculation.	Word supports formulas in table cells for calculations and logical comparisons, but the feature is designed for document tables rather than a full spreadsheet workspace.	The Google Docs product page highlights collaborative document editing, comments, smart chips, and document structure features rather than spreadsheet-style function editing inside Docs.	Notion formulas can perform calculations with database properties, built-ins, and functions inside database workflows.	Acrobat lets you configure calculation rules for PDF form fields so values can update after users enter form data.
WPS Advantages	Advantage: IMTAN works directly in spreadsheet cells, which fits repeated calculations, cell references, and day-to-day worksheet analysis.	Compared with WPS: formula entry is available in Word tables, but the workflow is centered on document tables instead of spreadsheet analysis.	Compared with WPS: Docs focuses on document collaboration; spreadsheet-style function analysis is handled in Google Sheets rather than Docs.	Compared with WPS: formulas are oriented to database properties and workflow logic, not worksheet cell formulas across a spreadsheet grid.	Compared with WPS: calculation features are designed for PDF forms, not worksheet formula editing or large-scale cell analysis.

Overall Conclusion
If you need to enter formulas directly in worksheet cells, reference other cells, and keep results updated as data changes, WPS fits standard spreadsheet work more closely. The other products listed here also support calculation-related workflows, but they focus more on document tables, database properties, or PDF form fields.
