Sudoku! - sudoku spreadsheet

It started with sudoku puzzles in newspapers and magazines.
But sometimes they are too dificcult. Needed an enlarged copy, pencil, and eraser to solve them.

With a spreadsheet its a lot easier. Added some formulas to help. Functions in VBA to make that easier.
A macro to enter the puzzle, test my solution, and erase it to start al over again.
A macro to give some hints when I'm stuck. A macro so excel will solve the puzzle...
Al that is in the folder Sudoku_0
[Sudoku_0]
