Describe the problem/error/question
Hey guys, I have a problem when I try to connect my Microsoft Excel 365 account to n8n. Everything seems to be connected into my credentials, but I can’t seem get access to my workbook, sheet, etc even though n8n tell me that everything is connected. Have you ever encountered this issue, if yes what have you done to overcome it.
Check your Microsoft app permissions in Azure. The Excel node needs specific Graph API permissions like Files.ReadWrite.All or Sites.ReadWrite.All depending on where your workbook lives (OneDrive vs SharePoint).
Also verify the workbook ID or path you are using in the node. Sometimes n8n connects fine but cannot find the file because of incorrect sharing settings or the file is in a location the app cannot access.
Try listing files first with Microsoft Graph node to confirm your token can actually see the workbook before using Excel node.
I gave it all the permissions it need : Calendars.Read, Calendars.Read.Shared, Calendars.ReadWrite, Chat.Read, Contacts.Read, Contacts.ReadWrite, email, Files.Read.All, Files.ReadWrite, Files.ReadWrite.All, Mail.ReadWrite, Mail.ReadWrite.Shared, Mail.Send, Mail.Send.Shared, MailboxSettings.Read, offline_access, openid, profile, Sites.Manage.All, Sites.Read.All, Sites.ReadWrite.All, Team.ReadBasic.All, User.Read and I cant’t even see a workbook a sheet or whatever.
This is the error that it says when I try selecting the workbook list : Could not load list
