Hello there, s-fshaw89. Let’s take a closer look at your file format to ensure your Chart of Accounts uploads successfully to QuickBooks Online.
The error you're encountering may be caused by formatting issues in the Excel file that prevent QuickBooks from reading the data.
To resolve this, ensure your spreadsheet includes the required columns, such as Account Name, Type, Detail Type, and optionally Account Number. Be sure to remove any blank rows between the header row and your account data, as these can cause the system to interpret the file as empty.
For detailed guidance on uploading your Chart of Accounts, refer to this article: Import your chart of accounts to QuickBooks Online.
