I know it is possible to define on an excel file some custom properties. And this properties can take the value from a determined excel cell.
With this properties created, in a document library you can create columns with the same name as the custom properties. Then when uploading this excel file to SharePoint, this SharePoint columns automatically get the value defined in the custom properties.
So at the end, the SharePoint column gets the value reflected on the excel cell at the moment the document was uploaded.
What I don't know, is if this behavior can be configured somehow bidirectional, this means, after uploading the excel file to SharePoint, if I edit the value of the SharePoint columns, the change gets reflected in the excel cell or on the custom property.
There is anyway to achieve this?
