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
“ICU MessageFormat JSON — IT Pad” is a deterministic Novus Examples fixture for Internationalization, Localization catalogs. Parallel text and accented, multi-script content, for testing translation pipelines, Unicode handling, and localization tooling.
Documented properties for this file: JSON · 151 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.
Translation-catalog fixtures carry the same message set across formats, each with its native placeholder syntax. Test your i18n loader, catalog converter, or translation-memory tool, and use the RTL and CJK variants to check bidirectional text and Unicode handling.
Load the catalog with your i18n framework and verify placeholder interpolation and plural handling; the RTL and CJK variants exercise bidirectional text and font fallback.

- jsonICU MessageFormat — Apostrophe and brace quotingThe quoting rules that make ICU messages surprising: a single quote starts a literal section only when the next character is one ICU cares about, a doubled '' is always one apostrophe, and '#' inside a plural branch is a literal hash. Every message is paired with the exact string it must produce.
- jsonICU MessageFormat — Nested select/plural (Arabic)Arabic ICU MessageFormat catalog whose messages nest a select inside a plural branch and a plural inside a select branch, shipped with the argument bindings and the exact output each one must produce. Includes the '#' binding trap: inside a nested plural, '#' refers to the inner argument, so the outer count is written explicitly.
- jsonICU MessageFormat — Nested select/plural (English)English ICU MessageFormat catalog whose messages nest a select inside a plural branch and a plural inside a select branch, shipped with the argument bindings and the exact output each one must produce. Includes the '#' binding trap: inside a nested plural, '#' refers to the inner argument, so the outer count is written explicitly.
- jsonICU MessageFormat — Nested select/plural (Polish)Polish ICU MessageFormat catalog whose messages nest a select inside a plural branch and a plural inside a select branch, shipped with the argument bindings and the exact output each one must produce. Includes the '#' binding trap: inside a nested plural, '#' refers to the inner argument, so the outer count is written explicitly.
- jsonICU MessageFormat — Plural offset (English)The 'Rana and 5 others like this' pattern: ICU plural arguments with offset:1 and offset:2, where the explicit =0/=1/=2 selectors match the RAW value but '#' prints the value MINUS the offset. Ships every boundary case with its expected output.
- jsonICU Plural-Category Probe — Welsh (six categories, both kinds)Welsh is the only CLDR locale that uses all six plural categories for cardinals AND all six for ordinals, which makes it the strongest single probe for a plural-rule engine. Each branch names its own category so the assertion is about selection, not wording, and the two rule sets disagree for n = 4, 5, 7, 8 and 9.
