Log Timeline Builder
Turn raw logs into an ordered timeline for rapid triage and investigation.
Paste log lines or upload a log file to build a chronologically sorted timeline. The tool automatically detects timestamps, severity levels, and sources, then generates a filterable timeline with export options.
Use cases: Incident response triage, correlation of events across multiple systems, reconstruction of attack timelines, identification of temporal patterns in security logs.

Frequently Asked Questions
Are files uploaded to a server?
No. All parsing and analysis runs entirely in your browser. No files are uploaded to any external server.
What file formats does this tool accept?
Typical supported formats: .log, .txt, .json. If your format is not listed, try exporting or providing a compatible file.
Can I analyze large files?
Large files may be slow or memory-intensive in the browser. For very large datasets consider using a local specialist tool.
Which log formats are supported?
The tool supports syslog format, ISO 8601 timestamps, generic date/time formats, and CSV files with timestamp columns. The parser is flexible and can handle most common log formats.
Does the tool parse CSV files?
Yes. CSV files with timestamp columns (labeled timestamp, date, or time) are automatically detected and parsed. Events are extracted from the entire row and sorted chronologically.
What happens to lines without timestamps?
Lines without recognized timestamps are counted as skipped and reported in the results. This helps you understand coverage and identify malformed log entries.
Can I filter the timeline after building it?
Yes. You can filter by severity level (error, warning, info, etc.) and search for specific keywords in the log messages to focus on relevant events.
