Iterating through all the cells in Excel VBA or VSTO 2005

Question

I need to simply go through all the cells in a Excel Spreadsheet and check the values in the cells. The cells may contain text, numbers or be blank. I am not very familiar

Answer 1

If you're just looking at values of cells you can store the values in an array of variant type. It seems that getting the value of an element in an array can be much faster than interacting with Excel, so you can see some difference in performance using an array of all cell values compared to repeatedly getting single cells.

Dim ValArray as Variant
ValArray = Range("A1:IV" & Rows.Count).Value

Then you can get a cell value just by checking ValArray( row , column )
