Have you ever set the fill color of an entire sheet (or workbook) to white just because you didn’t want to see the gridlines? Well if you have a large file, you could literally reduce the file size in half by not coloring the cells. Simply remove the gridlines (after all that’s what you wanted to do in the first place isn’t it?).
Copy all of the code below. Paste it into your workbook’s Visual Basic editor, either under a Microsoft Excel Object or Module.
