Append Text to End of File Name for Multiple .xlsx Files in a Folder
<p>I have a large amount of excel files in a folder and I need to append -MN to the end of all the file names. I've looked around the web for a solution but haven't had much luck finding a clear answer.</p>

<p>For example:</p>

<p>examplefile.xlsx would become examplefile -MN.xlsx</p>

<p>Any help would be greatly appreciated! Thank you!</p>
