About This Feature

Overview

BESSELI is a built-in formula function in WPS Office for Windows AirSheet for spreadsheet calculation and analysis. It is suitable for modified Bessel function calculations in worksheets and supports spreadsheet workflows such as formula entry, cell references, and recalculation.

Core capabilities include:

Entering the BESSELI function directly in a cell or in the formula bar.
Viewing syntax prompts while typing the function name to confirm argument requirements and examples.
Using cross-worksheet references, nested calculations, and automatic recalculation after data changes.

This function is useful for engineering calculations, mathematical analysis, classroom demonstrations, and batch worksheet processing.

System Requirements

Item	Requirement
OS	A Windows device that can run WPS Office normally
App version	The latest version of WPS Office is recommended; BESSELI is supported in AirSheet across versions
Network	Local formula calculation does not require a network connection; downloading, installation, and account-related actions require internet access
Other	You need to open or create an editable AirSheet file and have permission to edit cells

Download & Installation

Before using BESSELI, install WPS Office on your Windows device and open AirSheet.

Compare with Alternatives

Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	In AirSheet, you can type `=BESSELI(` directly and use syntax prompts, cross-worksheet references, nested calculations, and automatic recalculation.	Microsoft Word officially supports formulas in tables for calculations and logical comparisons, but the scenario is mainly limited to Word table formulas rather than a spreadsheet function library.	The official Google Docs page highlights Gemini for drafting, summarizing, and asking questions, and does not describe an equivalent in-document spreadsheet function workflow.	Notion officially provides formula syntax and functions for databases, using properties, functions, and operators for calculations, but the workflow is centered on database properties.	Adobe Acrobat officially supports calculations for PDF form fields, which is useful for form totals and linked fields rather than general spreadsheet formula editing.
WPS Advantages	Advantage: Better aligned with spreadsheet cell calculations. Distinct: Syntax prompts appear while typing, with support for cross-sheet references and nested formulas.	Compared with WPS: Word formulas are more suitable for basic calculations inside document tables, with a narrower formula-entry and data-analysis workflow.	Compared with WPS: The official Google Docs page focuses on AI writing assistance and does not describe the same kind of worksheet function editing workflow.	Compared with WPS: Notion formulas depend on database property structures, while WPS fits traditional worksheet cell entry and batch calculation more directly.	Compared with WPS: Acrobat calculations focus on PDF form fields, while WPS is better suited to ongoing worksheet editing, references, and recalculation.

Overall Conclusion

If your main work involves spreadsheet formula entry, references, and automatic recalculation, WPS follows a workflow that is closer to a standard worksheet experience. Other products also provide calculation-related features, but they are more focused on document tables, database properties, or PDF forms.

Use Cases

#	Scenario	Target Users	Core Pain Point	Solution
1	Engineering parameter calculation	Engineers and researchers	Need fast modified Bessel function results in a worksheet	Enter the BESSELI formula in a cell and return the result directly
2	Classroom formula demonstration	Teachers and students	Need to see function argument patterns while typing	Use syntax prompts to confirm the formula structure quickly
3	Cross-sheet analysis	Data analysts	Need to reference data across worksheets and calculate consistently	Use cross-worksheet references and nested calculations
4	Batch result updates	Finance and operations staff	Need multiple results to update after source data changes	Use automatic recalculation to reduce manual refresh work
5	Formula troubleshooting	General office users	Errors are hard to locate after entering a function	Check syntax prompts, arguments, and recalculation behavior
