I built LocalParse to make

I built LocalParse to make structured data easier to inspect directly in the browser. Its dark interface combines an expandable tree with clear file-format information and JSON/JSONL export controls.

I also completed a focused reliability pass: preserving JSONL labels during expansion, clearing stale export data, surfacing malformed input, and safely displaying object keys. The fixes are backed by 29 regression tests. Screenshots use synthetic sample data.
