Size and count limits for every file control in this wave, together with the rejection codes an application would return. HTML expresses none of these, so the manifest is where they have to live.

What is a .json file?

JSON (JavaScript Object Notation) is a lightweight, text-based data-interchange format representing objects, arrays, strings, numbers, booleans, and null. It is language-independent, human-readable, and the dominant format for web APIs and configuration. It requires a single well-formed root value.

How to use this file

Use an example JSON file to test parsers and serializers, schema validation, Unicode and number-precision handling, and API request or response processing.

How to use this file for testing

“Upload Constraint Manifest (JSON)” is a deterministic Novus Examples fixture for Form parsing, Form testing, JSON parsing. PDF AcroForms with documented fields and live HTML forms for testing form parsers and fillers.

Documented properties for this file: JSON · 2,193 bytes. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.

This form is fictional SAMPLE content for tooling tests (autofill, scrapers, PDF fillers). It is not an official government, bank, or clinic form. Open the HTML offline or fill the PDF in any viewer; the demo submit path never stores data.

Code examples

import json

with open("upload-constraint-manifest.json") as f:
    data = json.load(f)
print(type(data), len(data))
