How to use this tool
- Paste a schema or select one UTF-8 file.
- Use one supported type per node and only the documented finite keyword set.
- Select Generate deterministic sample, then download the sample and complete generation report.
Examples
The default schema generates a required name of a and an age of18.
Limitations
- At most1MiB source,10000schema nodes,30schema/generated levels,50000generated nodes,1000items per array,10000UTF-16units per generated string,5MiB combined output and30seconds.
- const wins, then the first written enum entry, then deterministic construction. A refused first candidate does not establish that the schema has no valid witness.
- Only the listed finite Draft-07 subset. No references, formats, patterns, compositions, remote fetches, randomness or general satisfiability search.
- Numeric schema and literal tokens allow at most 100 coefficient digits and five written exponent digits, with exponent value from -1000 through 1000. Extra exponent zeros are not normalized around this admission.
