One feature that would be awesome in the OnlyOffice spreadsheet would be the ability to mark a cell as a “Stock” Data Type, and then be able to request live stock quotes. One of my Excel sheets does this, and when I try to open the sheet in OnlyOffice, the “stock” cells show as “#VALUE!”.
If there is a way to do this via a plugin perhaps (even if it is different than the Excel way), I would love to know about it.
