The best way to learn is to search this site (above tool), then pick topics that you find interesting or of use to you. Copy the code into a workbook, add some data if necessary, run the code.
Then get into the code and change the way it works or add things to it. Use the builtin help to lookup how MsgBox's or InputBox's work add some of them. Lookup builtin Excel functions or how to use Application Workbook functions in code. How to pull data from a worksheet or add new info to that sheet, whatever?
On this site you can look at Bill's books all are good the last two are best for coding.
