What this tool does not do / Limits
This reads only pasted text. It cannot open your Windows Event Viewer, and it does not explain what an Event ID means — check Microsoft documentation for the meaning of a specific ID.
Frequently asked questions
Does this read my computer's event logs?
No. Paste lines you copied yourself; nothing is read from your device.
What if a line has no Event ID?
It is counted under Unknown for the ID tally, but it still counts in the total and level tally.
