How it works
This tool scans each log line for level keywords (ERROR, WARN, INFO, DEBUG, TRACE), timestamps, and JSON payloads, then wraps them in styled HTML spans for colour coding. Processing runs in your browser.
Common use cases
- Prettify compact JSON log lines from application servers
- Highlight log levels and fields for easier scanning
- Format raw log output from CI pipelines for review
