The first row of your file, which specifies template type and version, has been modified and can no longer be read. Please download a new version of this template and use it to upload your data, making sure not to modify the first row.
This error occurs when the first row of your inventory file does not match a known template type or version number. In order for Amazon to successfully process your inventory file, you must specify the template type (such as Clothing or PetSupplies) and version number. The proper information for your inventory file is already located on the first row of the template.
To resolve this error:
Compare the first row of your inventory file with the first row of the appropriate inventory file template.
Modify the first row of your inventory file so that it matches the first row of the template.
If you are editing your inventory file with Excel, Cell A1 should contain the template type and Cell A2 should contain the version number.
If you are editing your inventory file with a text editor, a single tab on the first row should separate the template type and version number.
Save your modifications.
Resubmit your inventory file.
