As answered by people managing eInvoiceTool and ShellNewHandler.
eInvoiceTool's answer
It covers the main European e-invoice formats in one free tool: Polish KSeF, German XRechnung, ZUGFeRD / Factur-X and Peppol UBL. You can both read an invoice as a normal document and validate it against the official rules. Everything runs in the browser, so invoice files never leave your computer.
eInvoiceTool's answer
Small businesses, freelancers, accountants and bookkeepers in Germany, Poland and other EU countries who receive e-invoices as XML or PDF files and need to read or check them. It is also useful for developers testing invoice exports against XRechnung, Peppol or KSeF rules.
eInvoiceTool's answer
Most viewers or validators handle a single format, require an account, or upload your invoice to their server. eInvoiceTool is free with no signup and no limits, works with KSeF, XRechnung, ZUGFeRD and Peppol, and keeps files private because nothing is uploaded. Error messages show the official rule ID with a plain explanation, and the interface is available in English, German and Polish.
eInvoiceTool's answer
WordPress for the website, with a custom plugin written in plain JavaScript. Invoices are parsed and validated fully client-side in the browser; the validation rules are based on the official EN 16931, XRechnung, Peppol BIS and KSeF specifications.

I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
