Common errors & troubleshooting
Unexpected token / trailing comma
Cause: JSON does not allow trailing commas after the last property.
Fix: Remove the extra comma, or fix quotes, then run validation again.
Unclosed object or array
Cause: A `{`, `[`, or quote was opened without a matching closer.
Fix: Check brace balance and string quotes, then re-run.
Empty input
Cause: The editor is empty.
Fix: Paste JSON or use Load example before running JSON Splitter.

- Opening a local file uses the browser File API; the file is not uploaded to UtilityKit.
- We may collect anonymous product analytics (for example page views). Tool contents are not included in those events.
- JSON Splitter runs in your browser; extremely large inputs may be slow or limited by device memory.
- Results depend on your browser’s JavaScript engine and available APIs.
