Sample JSON files — free downloads for parser tests
Last updated 2026-05-20
Free, hot-linkable .json files in eight common shapes. Use them to smoke-test parsers, benchmark renderers, or seed fixtures in your test suite.
Each file ships with a preview, the byte size, line count, and a primary Download button. Large files are preview-only on the page; the full payload lives at /downloads/sample-*.json and inside the repo at datasets/.
Small (~1 KB)
A single object — quick smoke test or tutorial placeholder.
Medium (~50 KB)
List of ~100 user-like records with nested fields.
Large (~1 MB)
List of 3,500 detailed records for stress tests. Preview-only.
Formatted
Pretty-printed, 2-space indentation. Identical data to the medium file.
Minified
No whitespace. Useful for size-budget tests.
Invalid
Deliberately broken — unquoted key, trailing comma, missing brace.
Nested
Twelve levels deep — recursive renderers and schema tools.
Array-heavy
Top-level array of 10,000 items. Preview-only.
