About Log Lens

Log Lens is a desktop viewer for searching and filtering very large log files. Its description says it can work with multi-gigabyte files containing tens of millions of lines without loading the entire file into memory. Users can build nested Boolean search groups, such as combining alternatives with additional required terms, and merge multiple files into one timeline sorted by timestamps. The viewer colors log levels and method names, detects embedded JSON payloads and formats them for easier reading, and supports selecting text with the cursor for copying. Together, these capabilities help users narrow large logs, compare events across files, and inspect structured data within log entries. The evidence does not list supported log formats or specify timestamp parsing rules.
