Suggestion Description:

Currently, Confluence Excel Macro does not allow users to import and preview .CSV files, although this is a widely used file format. Although you can import .CSV files to a page, Preview doesn't work and neither does Excel Macro convert it to a table, as it does for .XLSX files. The expectation here is to modify the add-on so users can import, preview and append .CSV files as a table to Confluence pages.

Preview of .CSV Files

Expectation:
When we attach a .CSV file to a Confluence page, we expect it to provide us with a Preview, as it does for regular .XLSX files.

Reality:

1. Preview doesn't Work:
   
2. It also doesn't work when you click on it:
   

Excel Macro

Expectation:

1. We can use the Excel Macro to convert .CSV files to a table in Confluence pages, which would be the same feature already available for .XLSX files.
   
2. Table:
   

Reality:
.CSV Files are not allowed by the Excel Macro.
