What Sparkpond Data Tools is
Sparkpond Data Tools is a collection of focused browser utilities for cleaning, analysing, organising and converting tabular data. The project favours a precise tool for each problem over a generic editor full of hidden assumptions.
Why processing is local
Data files often contain customer, financial or operational information. Keeping parsing and export in the browser removes the application upload layer and lets users verify network behaviour themselves.
Product principles
No account, no download paywall, no invented popularity claims, no silent destructive repair and no file data in analytics. CSV, TSV, JSON, NDJSON and XLSX support is documented per tool rather than claimed everywhere.
Updates
Content dates change only when content or behaviour changes. Releases are recorded in the changelog and dependencies stay pinned with public notices.
