Open .xlsx, .xlsm, .xls, .ods, .csv and .tsv files in VS Code as a fast, read-only grid with sheet tabs, sort, filter and smooth scrolling through large files. Free, with no nags, no telemetry and no account. It runs fully offline.
The free version is complete on its own. Sheet Glance Pro is an optional add-on for a one-time $9, with no subscription. It adds CSV/TSV editing with save and undo (untouched rows are saved exactly as they were, in the file's original encoding), search across all sheets, column stats, export to CSV, TSV, JSON or Markdown, and comparison of two sheets or files. Also fully offline, with no account or license key.
