For many people Sudoku is a Japanese game, but it is a Swiss mathematician “Leonhard Euler” who is considered its creator (Euler — Wikipedia)

It is believed that it was he who originated the Sudoku pastime, creating a series of guidelines for the calculation of probabilities.

For those of us who have studied Physics, Mathematics, Any Engineering, Economics, Business and/or… talking about Euler is like talking about Johan Cruyff in Holland.
Trying to create a Sudoku Generator in Excel, as well as a Sudoku Solver in Excel, became a personal challenge.
It was great to expose it and/or present it in Excel, a mathematical game that logically should be able to be played and solved, in the best existing calculator, that is to say in EXCEL.
A Game easily presentable in an Excel sheet, for whose resolution we could use many of the existing functions in Excel.
The first Sudokus Solver was made in 2004/2005, more as a personal challenge.

We tested it with hundreds of Sudokus to see if it worked and/or hung in its resolution. But we observed that our Sudoku solver in Excel was able to solve any Sudoku.
To this day we have not been able to find a single Sudoku that we have not been able to solve, the vast majority of them in less than 3 seconds.
For Programmers and/or people interested in learning VBA, it can be useful.
I understand that this solver is the most downloaded of the Sudoku Solvers made in Excel/VBA.
