Browser-based data cleaning tools

The cluster is a set of browser-based tools for cleaning, validating, converting, and profiling CSV and JSON data locally without uploading files. Its dated history before the index is too thin to read a shape from: only two dated entries exist, so the cluster either predates the index or most members are undated. On traction, jira-puller leads with 0 stars, followed by ericaqa-api-runner and microapp-factory, also at 0 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.
