How to Read an UBL/XML Invoice Easily

Decoding a not-so-readable format…

You receive an electronic invoice in UBL/XML format… and when you open it, you see a block of text that makes no sense? That’s normal: this file is designed for software, not for humans.

What’s inside a UBL file?

The UBL (Universal Business Language) format is structured like a data tree. It includes all the usual invoice details: supplier, customer, date, amount, VAT, line items and totals. But everything is encoded in a technical language called XML (Extensible Markup Language).

<Invoice> <cbc:ID>2025-001</cbc: ID> <cbc:IssueDate>2025-10-01</cbc: IssueDate> <cbc:InvoiceTypeCode>380</cbc: InvoiceTypeCode> <cbc:DocumentCurrencyCode>EUR</cbc: DocumentCurrencyCode> ... </Invoice>

This kind of content is perfect for accounting software but nearly impossible for humans to interpret without the right tool. You can’t visualize the invoice clearly without reformatting it.

Why it’s unreadable without the right tool

Opening a UBL file in a basic text editor shows only nested tags — no layout, no structure, no clarity. Manually decoding it is tedious and error-prone.

Possible solutions

  • Some ERP and accounting systems can import UBL files and extract the data.
  • Others simply store the file without displaying it.
  • Until recently, there was no easy way to view or print a UBL invoice without complex software.
