# Sample JSON files for testing parsers and APIs, free and CC0 6 JSON test files from 708 B to 10 MB. Direct URLs, a SHA-256 for each and CC0, so curl and CI can fetch them with no signup and no keys. The page: . `json/people-10.json` is a sample JSON file: an array of 10 people objects, free to hotlink or download. | Path | Size | MIME | Properties | |---|---|---|---| | [`json/people-10.json`](https://loremfile.dev/json/people-10.json) | 5.2 KB (5,186 bytes) | `application/json; charset=utf-8` | utf-8, LF, 182 lines | JSON is the common language of APIs, and most JSON parsers are fine until they meet a number, a string or a depth they did not expect. These files cover the everyday case and the awkward ones. `json/people-10.json` and `json/people-1000.json` are arrays of people objects from the shared synthetic dataset, pretty-printed with two-space indentation; the same records appear in the CSV, Parquet and SQLite people files. `json/all-types.json` exercises every scalar shape worth testing: null, booleans, negative zero, exponents, integers beyond 2^53 and 2^63, Unicode escapes, a surrogate pair and empty containers. JavaScript's `JSON.parse` silently loses precision on the large integers, which is what the file is for. `json/nested-100-levels.json` nests an object 100 levels deep, for parsers with a recursion limit. For size limits, `json/1mb.json` and `json/10mb.json` hold people objects fitted to within 5% of their nominal size.
