CSV Studio
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)
- Export CSV (save), JSON (new editor tab), TSV (save as)
Usage
- Open a
.csv or .tsv file — it opens in CSV Studio by default.
- Or right-click a CSV in the Explorer → CSV Studio: Open as CSV Studio.
- Edit cells directly; changes sync to the file and respect
files.autoSave.
- Use the toolbar or command palette (
CSV Studio: commands).
