View and edit CSV and TSV files as an interactive spreadsheet inside VS Code.

Features

  • Custom editor for .csv and .tsv files with a scrollable grid
  • Inline cell editing with Tab, Enter, and arrow navigation
  • Toolbar: add/delete rows and columns, sort, filter, undo/redo, find & replace, export
  • Sticky header row and row-number column
  • Column: click to sort, double-click to rename, right-click menu
  • Row: click to select, right-click to insert, delete, or duplicate
  • Filter bar per column (substring, case-insensitive)
  • Find & replace panel with regex and whole-cell options
  • Virtual scrolling for large files (configurable threshold, default 5000 rows)
  • Copy/paste with Excel/Sheets-compatible tab-separated clipboard
  • Document sync with the underlying file (VS Code undo, auto-save, external edits)

Usage

1. Open a .csv or .tsv file — it opens in CSV Studio by default. 2. Or right-click a CSV in the Explorer → CSV Studio: Open as CSV Studio. 3. Edit cells directly; changes sync to the file and respect files.autoSave. 4. Use the toolbar or command palette (CSV Studio: commands).
