Excel and XML

Can I issue an e-invoice from Excel?

⚠ Machine-translated answer, not yet manually reviewed. For the exact wording, see the Slovak original.

Short answer

Excel can be the data source, but the mandatory e-invoice must be created as a valid structured document in a supported format and pass checks.

Entrance

Excel can help

The table can carry document number, partner, item, prices, rates and payment information.

Output

XML is critical

The result must be a structured invoice that is verified by the validator and processed by the partner.

Risk

Not enough columns

Missing numbers, wrong units or amounts can break the export even with a nice table.

Archive

We need an evidence package

Save XML, report, preview and link to original data source.

Conclusion

Use Excel as an input aid, not as the final e-invoice format.
