XSDHub

XSDHub lets Claude check XML files and e-invoices against the published, official rule sets and explain what went wrong. What it does: - Check XML well-formedness, with the location of each error. - Validate XML against an XSD you supply (XSD 1.0 or 1.1) or against a pinned official schema package. - Validate e-invoices with fixed packages: EN 16931, XRechnung, Factur-X/ZUGFeRD (extracted XML), KSeF FA(3) (XSD only), Romania RO_CIUS and Croatia HR. Every result names the rule set and version it used. - Explain an error code or message such as BR-DE-15 and link to a guide with causes and fixes. - Search and read XSDHub's public guides on XML, XSD and e-invoicing. Scope: XSDHub checks technical rules only. It does not judge tax correctness and does not confirm acceptance by a tax authority, the Peppol network or a recipient. Access: no account needed. Anonymous use includes a daily allowance of validations. XML up to 10 MiB, XSD up to 1 MiB; external schemas are not fetched. Privacy: XML, XSD and results are processed in memory and are not stored or written to logs. Only the counters for the daily allowance are kept.
