Conformance checklist

Where every format in the registry stands, generated from the code and the test fixtures on each build. Back to the converter.

What it reads, country by country

Every EU country also sends Peppol BIS Billing 3.0, which converts fully. The tiles show each country's own formats; each one links to its page.

  • Converted to canonical JSON
  • Identified; parser still to come

Beyond the EU

Peppol PINT jurisdictions and Saudi ZATCA, mapped on top of the UBL parser. The PINT Schematron is not bundled, so these get the UBL schema check only.

Checklist by format

  • 46 of 46 formats have a parser; 44 convert at least one fixture, 21 of them from a real public sample.
  • 2 formats have a parser but no fixture that exercises it, and 1 have no fixture at all.
  • 2 detection rules are unverified. 38 formats run schema or Schematron validation.

Performance

Documents converted per second by convert() on bun 1.4.2 (darwin-arm64), measured 2026-10-16; peak memory is the resident set of a fresh process that converts the file once. Numbers depend on the machine; the CI gate compares ratios to a calibration loop, not these figures.
