Log Parser

Log Parser

Turn log lines into structured rows with a regex — named capture groups become columns.

Pattern

Presets:

Use named groups like (?<ip>\S+) to name columns. One log line becomes one row.

Log lines

About this tool

Turn Apache, Nginx, and syslog lines into structured rows. Named capture groups become columns; export as table, JSON, or CSV. Free and client-side. Log Parser runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.

What this tool does not do

  • Log Parser is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
