VBA short code

There are 2 things to do: 1- Your job is to build a decrypter in Excel with VBA which will be used to decrypt a text file. Each letter has been shifted up 5 letters. For example, a has become f, n has become s, and x has become c, and so on. In order to do this you will need to divvy up each letter in the file into a separate cell in Excel. Write a macro that uses ActiveCell to go through all the filled up cells and converts each letter back to the original letter. After this is done get the letters back into paragraph form and put them in a Word doc. 2- check the code that I did for conversions equations.
