About JSON files
JSON test files from 10 KB to 10 MB are available free. They hold array data containing Japanese text, so they exercise a structure close to a real API response.
Because JSON validity cannot be determined without parsing the entire document, the cost of "read it all just to validate" grows with file size. These files help you decide when to switch to a streaming parser.
Typical uses
- Testing how a REST API handles a large response
- Benchmarking JSON parsers and serialisers
- Observing front-end behaviour when rendering a large dataset
- Checking that nesting depth and large-integer precision survive intact
