Spreadsheet fields need to be enabled by an Instance admin, as described here: https://labnotebook.ch/index.php/docs/admin-documentation/new-entity-type-registration/set-properties-as-rich-text-editor-or-spreadsheet/
The spreadsheet supports some basic Excel functionalities, such as mathematical formulas (e.g. =SUM(A1+A2)).
It is possible to import an openBIS Object into the spreadsheet, with the import button, on the spreadsheet itself:
Please note that if the Object is updated in openBIS, it will NOT be updated in the spreadsheet.
