Can I export to PDF or CSV on this page?
No, this page is a dedicated Viewer and Formatter. To export your JSON data to PDF, CSV, or Excel, please use our JSON Converter, which is specifically built for file transformations.
How does it handle nested JSON objects?
Our engine flattens nested objects into a single-level table using dot-notation headers. For example, a nested "city" inside an "address" object will appear under a column named address.city.
Is there a file size limit?
Our tool uses virtualized rendering, allowing it to handle JSON files with tens of thousands of rows smoothly. The only limit is your browser's available RAM.
