offiece2textile: VBA Add-ins which convert Microsoft Office contents (Excel and PowerPoint) to textile format
I released my Excel/PowerPoint Add-ins which converts Excel and PowerPoint contents to Textile.
I hope they would help the Redmine community.
Visit https://sourceforge.net/projects/office2textile/ for details.
(They are not Redmine Plugins, but I cannot find any other good place to share this release. Let me know if there is a better place.)
