tool to convert data from excel to create evenly spaced

Ok, here's a request to those alot more experienced than I am.  Here's what I'm looking to do and am looking for some feedback

• overall intent is to convert inputted data to evenly spaced columns of data - or an evenly spaced text table from copied data from excel
  
• create a tool where excel data is copied to a section - could be textbox, listview, etc, have observed that tabs are placed in between columns of data
  
• user would copy data from excel or html tables, and click a button to paste into the input data section
  
• user would select options then hit a button to convert data to aligned columns
  
• user then would copy the modified text table to the clipboard so then could be pasted into text based software
  
• input would be approx 15 columns wide and 100 rows long
  
• has an option to also enter  'space pipe character space' in between rows
  
• option also includes the number of spaces between columns, ie, from 2 to 6 spaces between columns
  
• this is work related tool for a monospacial font to handle various type of information exported from excel and create evenly spaced rows - could also be used for notepad or notepad++ without formatting
  
• we use excel tools with hidden rows that I don't want included - ie, if copy from excel with hidden columns, don't want that info to be placed into the converted text table
  
• included is a preliminary GUI and some sample information in the attached excel file
  
• temp files can be used to utilize clipboard to copy and paste data

Thank you in advance for your recommendations as I'm not even sure where to start.
