Microsoft Log Parser, made visual
An advanced GUI for Microsoft Log Parser 2.2.
Log Parser Lizard began as a graphical interface for Microsoft Log Parser 2.2—the mature Microsoft query engine that exposes Windows Event Logs, IIS/W3C logs, the registry, Active Directory, file-system metadata and other system data sources as SQL-queryable tables.
Microsoft Log Parser is an older utility, but its broad provider model remains practical and uniquely useful. Log Parser Lizard adds an intelligent editor, query management, advanced grids, charts, dashboards and exports, while also supporting newer SQLite-based workflows.
SELECT cs_uri_stem, sc_status, COUNT(*) AS Requests
FROM 'C:\inetpub\logs\*.log'
WHERE sc_status >= 500
GROUP BY cs_uri_stem, sc_status
ORDER BY Requests DESC;
SQLite / ULP
Search a folder for a reference
Point Log Parser Lizard at the file or folder and use familiar SQL to reduce it to useful evidence.
SELECT Department, COUNT(*) AS Records, SUM(Amount) AS Total
FROM 'C:\Reports\2026-*.csv'
GROUP BY Department
ORDER BY Total DESC;
One idea, the right interface for each job
Investigate visually. Automate repeatable work.
Start in Log Parser Lizard when the work needs context, comparison and human judgment. Move a trusted query to Universal Log Parser when the same task should run consistently in automation.
Flagship Windows desktop application
Log Parser Lizard

Refine SQL with an intelligent editor and reusable query library
Turn results into grids, charts, pivots and dashboards
Keep sensitive data local while applying human judgment

Referenced in technical books, respected blogs, professional training and security talks—and recommended by practitioners who rely on real operational evidence.
“I can’t say how much faster this tool made me once I had figured out LogParser.”
Log Parser Lizard has appeared in specialist books, respected engineering and security blogs, professional training, and conference material—including a Pluralsight Log Parser course and an RSA Conference session.
Log files and query results are processed locally. Their contents are not gathered, uploaded or used unless you intentionally submit information—for example, by email.
Yes. The current release is free to download and use. Future editions, features or pricing may change, but no payment is required for the current release.
Does my data leave the computer?
Supported files and query results are processed on the Windows computer running the application. Log contents are not uploaded to a hosted analysis service.
Is it only for log files?
No. It was built for log analysis, but providers also cover CSV, TSV, JSON, XML, text files, file-system data, Windows sources, databases and API output.
