It would help if you attached a sample Excel workbook.

To do this, click on Go Advanced (below the Edit Window) while you are composing a reply, then scroll down to and click on Manage Attachments and the Upload window will open. Click on Browse and navigate to (and double-click) the file icon that you want to attach, then click on Upload and then on Close this Window to return to the Edit window. When you have finished composing your post, click on Submit Post.

Do NOT try to use the Paperclip icon (Attachments button), as this does not work on this forum.

Your sample file should try to explain what data you have and what you want to do with it, maybe with a Before and After sheet to make it clearer.

Hope this helps.
