My students transcribed some records and entered into a Google Sheet. I also have it in an Excel file. There is a Dataset Item Type, but when I try to add the Excel file I get the following error:
The file ‘/tmp/php46PGGn’ could not be ingested because it has a disallowed MIME type (application/vnd.openxmlformats-officedocument.spreadsheetml.sheet).
I did see that you allowed the ability to add documents. I have added a pdf with no errors. I could save the data as a pdf, but that limits visitors’ ability to manipulate data.
