Invoice-first workspace
Open invoice XML, detect unfamiliar files, check VAT and IBAN details, apply formal XML validation where needed, and convert supporting PDF or image files without creating an account.
Common entry points for invoice review, identifier checks, and supporting file conversion.
What this site is for
Tooltensor helps with the most common invoice tasks: find the file type, read the invoice in plain language, check VAT and IBAN details, and validate structured XML when a workflow needs a deeper check.
Use the site to answer practical questions quickly: what file is this, can I read the invoice data inside it, can I run VAT verification with VIES, can I check if an IBAN is valid, and does this XML pass deeper invoice rules.
Business File Tools is the main product area. It groups the pages users actually need in sequence: detect an invoice format, open an unfamiliar invoice file, identify its format, and read the supplier, buyer, totals and line items without uploading anything to a server.
The PDF converter stays as a supporting utility because invoice workflows often include attachments, previews, archive exports, or image-based handoff steps. It is useful, but it is no longer the main identity of the site.
If a supplier, ERP, or access point gives you an unfamiliar file, start by identifying the file family before you forward it or try to read raw XML manually.
Once the file type is clear, open it in a readable summary so you can check supplier, buyer, totals, dates, and line items without scanning raw tags.
VAT and IBAN checks belong in the same cluster because they are common follow-up checks during supplier onboarding, invoice handling, and payment review.
Most file-reading and conversion steps still run in the browser so users can inspect invoice files locally instead of uploading them into an opaque third-party workflow. Live registry checks and formal XML validation only run on the pages that explicitly say they use a live or server-side step.
The pages explain exactly what was inspected, what was not inspected, and where a result is only a structural precheck rather than a legal or accounting decision.
The PDF converter stays available because invoice handling often includes previews, attachments, archive exports, or image-to-document handoff.
These pages represent the current product direction best and give new visitors the clearest path into the site, especially for users searching for an IBAN validator, VIES VAT verification, or a way to open a Peppol invoice XML file.
If you are working with XML or hybrid invoice files, start with the business tools cluster and move from detector to viewer or extractor. If the task is only a file format change, use the PDF converter directly.
