What are the limits of Log Data Analyzer?
Reads Apache/Nginx common or combined access logs, or JSON Lines with status/path/bytes and optional durationMs fields. Durations are milliseconds only when explicitly named durationMs. Unparsed lines are reported, never silently counted as valid requests. This is an offline summary, not live server monitoring. Inputs stay in browser memory. No workbook is created. Table limits: 5 MB total text, 25,000 rows, 64 columns and 200,000 cells; expensive operations have stricter limits. Processing can be cancelled.
