Log Workbench S is a VS Code log analysis extension focused on powerful log filtering and surrounding-row inspection. It also provides keyword search, timestamp filtering and formatting, sorting, CSV export, and performance statistics to help you investigate application logs efficiently.
Demo
Log Filtering and Keyword Search
Filter error, warning, and slow-operation rows, or search logs by keyword to focus on the entries you need.
Surrounding-Row Inspection
Inspect matching log entries with configurable surrounding-row options while keeping the results focused on the filtered log set.
