About Tooltensor

Tooltensor is built and maintained by Ronan, a developer based in Belgium with a background in web infrastructure and automation.

Tooltensor started as a broader utility project, then shifted toward structured invoice workflows when Peppol-based B2B e-invoicing became a practical requirement for many businesses. The main problem was simple: people were receiving XML invoice files, hybrid PDFs, VAT numbers, and participant identifiers without having a clear way to inspect them quickly in plain language.

Why Ronan built this version of Tooltensor

The current site is designed to help accountants, operators, finance teams, and small businesses answer practical questions fast. What file is this? Does this PDF contain embedded invoice XML? Can I read the supplier, buyer, totals, and line items without scanning raw tags? Does this VAT number or participant ID pass a useful first check before the workflow moves on?

What Tooltensor focuses on now

The main product area is the business file tools cluster. It covers invoice format detection, readable UBL and Peppol XML viewing, Factur-X extraction, live participant and VAT checks, formal invoice-rule validation, and support guides that explain how the formats differ.

How the tools are built

Where possible, Tooltensor processes files in the browser so users can inspect invoice data without uploading documents into an account system first. Some pages also run live registry checks or send XML to the Tooltensor validator service for formal rules validation. The tools use explicit parsing logic, clear output labels, and visible limitations instead of broad claims that the page cannot actually support.

What stays on the site

The PDF converter remains available because invoice handling often includes attachments, archive exports, and image-to-document conversions. It supports the business file workflows instead of acting as the site's main identity.

Corrections and updates

If something looks wrong, Tooltensor reviews the page and updates it where needed. You can read the full standards in the Editorial & Accuracy Policy.
