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).
