Read NDJSON logs as rows, not raw text.

What is NDJSON?

NDJSON—also called JSON Lines or JSONL—stores one complete JSON value on each line. It works well for application logs and streaming exports, but ordinary JSON formatters often expect one enclosing array and reject it.

Open the file directly

JSON Analyzer recognizes .ndjson, .jsonl, and log files. Each valid line becomes a row. Nested fields remain visible in the grid and can be flattened into dotted columns when you need a conventional table.

Find the event that matters

• Search every key and value.
• Filter a status, service, customer, or log-level column.
• Run a JSONPath-style structural query such as $.rows[?(@.status=="ERROR")].
• Export only the visible result to CSV, XLSX, Markdown, or JSON.

Private by default

Production logs frequently contain identifiers and internal data. The viewer processes ordinary files locally, so you do not need to paste sensitive logs into an online formatter.
