CII Factur-X EN 16931

Free CII Viewer Online

Open a CII or Factur-X e-invoice and read it like a paper invoice, right in your browser. Nothing is stored.

Drag and drop your invoices here, or click to browse.

Why open your e-invoice XML here?

XML is written for machines. This viewer turns it back into an invoice a human can read, check, and copy from.

Reads Like a Paper Invoice

Parties, line items, VAT breakdown, and payment details appear laid out the way an invoice should look, not as nested tags.

Copy Any Value

Everything is selectable text: grab the IBAN, the invoice number, or a line amount without retyping it from a PDF.

Nothing Is Stored

The file is parsed in memory and discarded immediately. What you view never leaves the request.

PDF When You Need It

One click turns the same file into a formatted PDF download for sharing or archiving.

How It Works

From machine file to readable invoice in two clicks.

Step 1

Drop In the File

Upload the e-invoice XML, or a hybrid PDF with embedded XML; the syntax is detected automatically.

Step 2

Read the Invoice

The structured data is rendered as a clean invoice layout: parties, line items, VAT breakdown, totals, and payment details.

Step 3

Copy or Download

Copy the values you need directly from the page, or download the same invoice as a formatted PDF.
