I can display e-invoice Excel?
Short answer
Yes, Excel may serve as an input table or temporary aid, but alone e-invoice must be valid XML in the right format. Excel file or PDF export from Excel are not e-invoice. In repeated exposure, it is safer to use a system that can validate and archive the result.
Excel can help
The table may bear the number of the document, partner, items, prices, rates and payment details.
XML is crucial
The result shall be a structured invoice validated by the validator and processed by the partner.
Columns Not Enough
Missing dials, bad units or amounts can break exports even with a nice table.
Need proof package
Save XML, report, preview and link to the original data source.
Conclusion
Use Excel as an input device, not as the final format e-invoice.
