How to use Log Formatter

  1. Paste log lines (one JSON object per line, e.g. NDJSON).
  2. Optional: put 'level:error' (or level:info, etc.) on the first line to show only that level.
  3. Click Format to pretty-print (and filter) JSON lines.
  4. Copy or download the formatted log.

Frequently asked questions

What if a line is not JSON?
Non-JSON lines are left unchanged when not filtering. When filtering by level, only matching JSON lines are included.
How does the level filter work?
If the first line is 'level:error', only log lines whose JSON has level equal to 'error' are shown (case-insensitive).
