Sample datasets

a few realistic XMLs for testing the tools on this site · updated 19 May 2026

Every tool here works just as well with your own XML, but sometimes you just want something to drop in and see what the output looks like. The files below are small, realistic, and cover the obvious edge cases — including a couple of intentionally broken files for testing the validators. Each link saves the file to your machine; nothing is uploaded anywhere when you then drop it into a tool.

Small starter files

Larger datasets

Bigger documents for stress-testing the formatter, validators, and converters — plus a deliberately broken file for the well-formedness checker.

How to use these

Click any card to download. Then drop or paste the file into whichever tool fits — the formatter for a quick pretty-print, the validator on the broken ones, or any of the converters. The intentionally-broken files (broken-*) are useful for trying parsers and seeing how they recover.

If you have a real-world file you'd love to see as a sample (anonymised, of course), email [email protected] and I'll add it. The smaller and weirder the better — the goal is to have files that exercise the tools, not pretty demos.
