Open NDJSON on Phone

NDJSON is a newline-delimited JSON format used for streaming records, logs, and datasets.

• A normal JSON viewer cannot parse the whole file as one JSON document.
• Invalid rows are hard to spot in raw text.
• Many mobile apps treat NDJSON as unknown text.

OpenOnPhone is for quick local inspection. It does not replace the original professional app for editing, conversion, exact layout, formulas, measurements, security review, or full workflow features.
