[xwiki-users] Excel plugin or $xwiki.calc ?

Hi all, I did a little search on the importing/processing excel files and I am confused a little bit: First of all, I found Excel plugin: http://extensions.xwiki.org/xwiki/bin/view/Extension/Excel+Plugin but it's status is obsolete - "The Plugin technology has been replaced by Components" - so is that functionality available out of the box in the latest versions of XWiki ? Moreover, in the comments we can read: $xwiki.ExcelPlugin should be updated to $xwiki.calc as this is the name of the plugin on a newer XE > 2.1.1 There is also another extension: Excel Import Scaffolding and it clearly points to the Excel plugin page. http://extensions.xwiki.org/xwiki/bin/view/Extension/Excel+Import+Scaffoldi… Could someone explain what is the proper way of working with excel files currently, I just don't want to tie my code to the obsolete components. Thanks, Piotr
