Log Parser

Parse JSON Lines logs or common access-log entries into JSON records.

Processing stays in your browser. Only the selected format is parsed; invalid lines are reported. This does not collect remote logs or infer application causes.

How to use the log parser

Parse JSON Lines logs or common access-log entries into JSON records. Complete the log lines, log format fields above, or upload a UTF-8 text file for the first field. Choose Run tool, review the output, then copy or download the result.

Two JSON Lines entries become two records in a JSON array.
