    1. COI could probably adapt that. I don't know the column count or data types beforehand, so I'd have to find a workaround. I was hoping there was something in Interop.Excel that would actually allow direct conversion to some data object, but I'll take what I can get.

    2. COInterop.Excel will not allow for direct conversion from one data type to another. It will give you access to the Sheets object so you could access each sheet and then iterate over each Range in that sheet, but that is it. Once you are there you will have to write the conversion code.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
