Project iSlice

 

ISlice is Excel formula scripting framework. It allows to link worksheet cells by buildeing descriptive data models in iSlice Editor - without use of incell formula typing.

ISlice framework consists of:

1. Model Editor - is used to define data cubes, slices and links between them;

2. Model Solver:

  • loads iSlice models;

  • connects to Excel through COM interface (or XLL API) as out of process exe or in-process dll (or xll) add-in;

  • does calculations on cells accordingly to user input.

Download source and bin files from SourceForge.net here

Important remarks:

 ISlice project is far from being completed in a way to be usefull for end user. For now it is more like a conceptual prototype, wich shows much of the intended functionality.

ISlice is written for Excel 2003 and most likely it will not work with other versions. Functionality may not be implemented in most effective or readable way.

This version of iSlice solver reads and holds in memory all in model defined worksheet data (cells).

 With source are included modified versions of GridCtrl by Chris Maunde, project XLW, MultilineList by Dave Calkins.

 

Bin files:

 iScEditor.exe – iSlice Editor

iScSolver.exe – iSlice Solver

iScSolverXll.xll - iSlice Solver as Excel xll add-in
