Compare with Alternatives

Comparison Item	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	Supports COUPNUM entry in worksheet cells, syntax prompts, and automatic recalculation for coupon-count analysis in spreadsheets.	Excel provides the COUPNUM function and documents settlement, maturity, frequency, and basis arguments for coupon-number calculations.	Google Sheets documents related coupon functions such as COUPDAYS and links COUPNUM in its related function references, showing support for coupon-date calculation workflows in spreadsheets.	Notion provides a formula system for database properties, including numeric, date, and logical expressions, but it does not present a dedicated COUPNUM-style securities function on the referenced help page.	Adobe Acrobat supports calculated PDF form fields such as sums and products, which fits form workflows rather than spreadsheet-based financial function analysis.
WPS Advantages	Advantage: WPS places COUPNUM directly in a spreadsheet workflow, so users can combine it with other worksheet formulas and review results in the same grid.	Compared with WPS, Excel provides a more detailed dedicated COUPNUM reference page; both products support spreadsheet-based coupon calculations.	Compared with WPS, Google's referenced help page emphasizes related coupon functions and cross-links rather than a dedicated COUPNUM article in the extracted page.	Compared with WPS, Notion focuses on database property formulas instead of cell-based financial functions.	Compared with WPS, Adobe focuses on PDF form calculations instead of spreadsheet financial modeling.

Overall Conclusion

WPS is well suited to users who want to calculate coupon counts directly in a spreadsheet and continue working with related formulas in the same worksheet.
