Sample datasets
Every tool here works just as well with your own data, 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 collections to stress-test the viewer and conversions. The polygon and city files are synthetic but schema-realistic, the airports file uses plausible-looking IATA/ICAO codes, and the broken file is for the validator.
How to use these
Click any card to download the file, then drop it on the input pane of
whichever tool fits. The intentionally-broken files (with names like
broken-*) are useful for trying the validators — they should
report specific line numbers and reasons.

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.
