Can someone please help me upload an existing Excel Spreadsheet into Confluence?
When I try, these are the errors I am receiving. Just an FYI, I am trying to upload the same generic file and getting different messages.
Since this is not the native Atlassian macro, it would be best to contact Bob Swift's support team. They can give you more assistance in solving the problem connected with their app.
Alternatively, you can try other apps which allow you to upload Excel Spreadsheets to Confluence, for example, our Table Filter and Charts app.
Here you can use the Table from CSV macro (it supports attachments and URLs). Note that to apply this macro, you need to save your Excel Spreadsheet in a CSV format.
