Desktop tabular data editors

This cluster consists of desktop applications for viewing, editing, and analyzing tabular data files such as CSV, Excel, Parquet, and others, with features like search, filtering, and large-file support. The dated history shows a single entry in February 2017, then a gap until July 2025, followed by entries in November 2025, January 2026, and June 2026, indicating sporadic additions over time. Traction is led by dataset-viewer with 1001 stars, far ahead of less-sheet (3 stars) and s3viewer (2 stars).

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
