Log / Stack Trace Formatter

About Log / Stack Trace Formatter

Format JSON log lines, filter records by severity, and inspect stack traces in your browser. Make diagnostic text easier to read without uploading logs.

How to use this tool

Paste logs or a stack trace and format them. Choose a severity filter when you want to narrow the displayed records.

What to know

Text severity recognition is heuristic. Keep the original log when investigating a failure so filtering does not hide relevant context.
