Beschreibung

XLPack is a set of expansion modules for Excel which is developed for easy numerical calculation of small and medium-size on office / home PCs. It adds the features useful for wide range of scientific fields to Excel.


XLPack consists of a worksheet function library, a solver add-in, and a VBA subroutine library. By using worksheet functions or a solver, numerical calculations can be performed without programming. Also, the VBA subroutine library can be called from Excel VBA so that the numerical calculation programming can be made easier.


(1) The worksheet function library provides worksheet functions that can be entered directly in the Excel worksheet. You can perform calculations such as linear equations, eigenvalues, and special functions simply by entering data in the Excel worksheet. (2) By using the solver, solutions for nonlinear equations, quadrature and ordinary differential equations can be obtained using the formulas entered in the Excel worksheet by menu operation. (3) The VBA subroutine library provides subroutines that can be called from Excel VBA. Using the professional numerical computation routines provided by the library, advanced numerical application programs for Excel can be developed easily.


XLPack works with Excel 2013 / 2016 / 2019 / 2021 / 365. No other development tools are required.


The other app "XLPack Basic" must be installed from Microsoft Store to use this app. XLPack Basic allows you to use basic 27 worksheet functions and 138 VBA subroutines/functions.


In addition, you can add more expert functions by installing this app "XLPack Addons" and purchasing additional Modules 1 to 4 with in-app purchase. Then you will be able to use a total of 148 worksheet functions and 902 VBA subroutines.


Online manuals and sample worksheets are provided on the website (https://www.ktech.biz/manual/xlpack-60-manual/).
