title: How to convert an .xlsx file in a .CSV file maintaining clickable links
body: <p>I have an xlsx file in which I have inserted some external links to the page to internet sites. There are also links to files in the folder that contains the worksheet. Now I should turn the xlsx file into csv format. I tried the "save as" function but the connections are lost and only the name is mantained (not URL or path). Simply renaming the workbook and putting ". csv" instead of ". xlsx" will keep the links if you open it with excel. However, opening it with a text editor makes the data unreadable. 
  Would you have a solution?</p>
