Windows Log Analyzer
Drop in a log file. Filter by severity or Event ID, search across all fields, visualize level distribution, and export filtered results to CSV or JSON. Everything runs client-side -- no data leaves your browser.
Supported formats:
Windows Event XML (exported from Event Viewer) •
IIS W3C logs (
u_ex*.log) •
Plain text logs

Note on .evtx files:
Binary EVTX cannot be parsed in the browser. Export from Event Viewer first:
right-click any log → Save All Events As... → XML.
Or use PowerShell:
Get-WinEvent -Path "C:\path\to\file.evtx" | Select-Object TimeCreated, Id, LevelDisplayName, ProviderName, Message | Export-Csv -Path "$env:USERPROFILE\Desktop\events.csv" -NoTypeInformation
