@denizmaral this is an opensource project. For the benefit of everyone it would be extremely useful if you write a description and purpose for this PR if nothing else.

hi @aparajit-pratap Do you know the latest state on this PR? Is this something we could ship now?

[pinzart90]

I think the changes in this PR need to be moved from DSOffice/Excel.cs to DSOfficeUtilities/Excel.cs
We moved all Excel types/dependencies into DSOfficeUtilities because of issues with embedded types and the Dynamo engine
FYI @aparajit-pratap @QilongTang @denizmaral

I will work with the team and try to get this shipped in Global launch this year
