″Failed to read the template file. The file format may be incorrect or the file may be corrupt.″ is displayed.

The application may not support the output pattern. Try the following.

• If the file has a complex layout, simplify the layout.
• In Excel, delete unused rows and columns. Excel normally saves rows with values and formatting, but for some reason an empty row may be recognized as a used cell and a large number of unnecessary rows are saved.
• In Excel, check for hidden and unnecessary sheets, and delete any unnecessary sheets.
• If Office functions (e.g., graphs, pivot tables, etc.) are used, remove Office functions. OFC may not support them.
• If images are included in the template file, reduce the file size of the images by lowering the image quality.
• Template files should be created in the Microsoft Office desktop version. Template files created by other applications, such as online versions, are not supported.
