✓Round-trip between formats (CSV ↔ JSON) to spot malformed rows quickly.
✓Everything runs locally in your browser — your input is never uploaded to a server, so it is safe for private or sensitive data.
✓Keep headers consistent — the first row usually defines your field names.
✓Use it to prototype data shapes before writing an import script.
✓Handles nested JSON and arrays, not just flat tables.
