Browser spreadsheet viewers and converters

This cluster is a set of web-based tools that ingest spreadsheet files (typically XLSX, CSV, OpenOffice, or LibreOffice formats) to display them in the browser, convert between formats, search across rows, generate charts, detect data quality issues, or produce reports and PDFs; a few entries are utilities like a file-reading library or a macOS menu bar helper that opens spreadsheets in Google Sheets. Its dated history is too thin to read a shape from: only two members have source creation dates before the index began collecting, and seven members have no source date at all. On activity signal, the leading members (school, open-in-sheets, and analysis-engine-pro) each have 0 stars, so no traction leader emerges.

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.
