Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	Enter `ISNUMBER(value)` in WPS Spreadsheet to test whether a value is numeric. It supports cross-sheet references, nested formulas, and automatic recalculation.	Excel includes the IS family of functions, and ISNUMBER returns TRUE when the tested value is a number.	Google Sheets provides `ISNUMBER(value)` and returns TRUE when the value is numeric or refers to a cell containing a numeric value.	Notion formulas support Number properties, conditional logic, and functions such as `toNumber()`, but it does not provide an ISNUMBER function with spreadsheet-style cell syntax.	Adobe Acrobat provides PDF and JavaScript automation features, but it does not offer a spreadsheet-style ISNUMBER function.
WPS Advantages	Advantage: Uses familiar spreadsheet formula syntax directly in WPS Spreadsheet. Distinct: Fits cell-based checks, cross-sheet references, and live recalculation on Windows.	Compared with WPS: Excel offers a similar numeric test function and is commonly used in complex spreadsheet models.	Compared with WPS: Google Sheets also supports the same function name, with a stronger focus on browser-based collaboration.	Compared with WPS: Notion formulas are designed for database properties rather than direct cell-by-cell spreadsheet formulas.	Compared with WPS: Acrobat JavaScript is aimed at PDF interaction and automation instead of spreadsheet formula evaluation.
