Frequently Asked Questions
What log formats are supported?
This tool handles JSON logs (one JSON object per line), standard log formats with timestamps and levels (INFO/WARN/ERROR), and Java/JavaScript/Python stack traces.
Can I filter by log level?
Yes. Click "Show ERRORs Only" or "Show WARNs Only" to filter lines containing those keywords. This works with most log formats that include level indicators.
