Log File RegExp Filter
Upload local log files and filter them in real-time using regular expressions or keywords in a color-coded terminal console.
How does this tool work?
A fast, fully client-side RegExp log file analyzer.
The tool reads log files locally via the HTML5 FileReader. Users can define RegExp patterns. The JS engine splits text into lines, tests each against the pattern, and outputs hits. Common log levels (Error, Warning, Info, Debug) are automatically highlighted in different colors.
Where are my data processed?
Only in your browser. Your data is not sent to any server.
The tool calculates and converts with JavaScript right on your device. Input and files are not sent to us or anyone else. You can check this yourself: load the page, disconnect from the internet, and the tool keeps working in the open tab.
