BESSELY
BESSELY helps you perform data calculation and analysis in AirSheet. It provides the tools you need to enter the function quickly, use flexible parameters for different calculation scenarios, and work more efficiently with automatic recalculation when source data changes. With BESSELY, you can write formulas by starting with =, view syntax prompts with parameter requirements and examples, use cross-worksheet references, and build nested calculations. If results show errors or seem incorrect, you can check syntax, parameter count and types, bracket matching, separators, text-formatted numbers, and circular references, or trigger recalculation manually. Whether you're entering a new formula, reviewing function syntax, or troubleshooting calculation issues, BESSELY helps you complete formula tasks efficiently.
