csvlite, the big-file viewer that refuses to panic

Editorial interest 86/100 Selection signal · not a rating of the site

A Windows and Linux desktop viewer for opening, filtering, profiling, pivoting, and exporting very large CSV and JSONL files.

Landing page captured for the 2026-08-28 issue.

Field notes

The page describes a local desktop workflow rather than an upload service: files are opened read-only, filtered in place, profiled by column, grouped into summary tables, and exported as CSV or PDF. Its benchmark example is an 8.0GB, 50-million-row ledger with 15 columns, with reported opening times of 4.3–8.5 seconds. The site also distinguishes typed sorting from displayed formatting, so values such as currency, percentages, and dates can retain their original appearance.
