Frequently Asked Questions

How large is the 10,000 record JSON file?

Approximately 800 KB. Large enough to test parsing performance and UI rendering, but small enough to download quickly on any connection.

Will JSON.parse handle 10,000 records?

Yes. JSON.parse handles 10K records in milliseconds on modern hardware. The real bottleneck is usually DOM rendering — use virtualization (react-window, tanstack-virtual) for displaying large lists.

Do you have even larger JSON files?

Our largest JSON file has 10,000 records. For bigger datasets, consider our CSV files (up to 1 million rows) or generate custom JSON with faker.js.
