Stack Trace Formatter
Make stack traces easier to scan without rewriting their content or changing frame order.
Inputs and files stay in this browser tab. These tools do not upload, log or save your data. Clear the workspace when finished.
How to use Stack Trace Formatter
Paste a trace or choose a TXT/LOG file, then select Format trace. Compare highlighted exception and caused-by lines. Expand library-frame groups as needed. Copy the text or download it with its original line endings.
Limits and interpretation
Language and frame classifications are heuristics and can be wrong for unfamiliar paths. Library groups are collapsed visually only; downloads include every original character; the operating system may normalize clipboard line endings. Generic text is preserved when no supported language is detected.
Is my input sent to a server?
No. Parsing, filtering and validation run locally. Only an explicit copy or download action exports your results. Closing this page clears its working input.
