Power CSV

An Excel-like, native-feeling CSV and TSV Tab Viewer and Editor for Visual Studio Code.

Features

• Native UI: Fits seamlessly into your active VS Code theme using the official Webview UI Toolkit interface components.
• High-Performance Grid: Leverages PapaParse and a highly virtualized <vscode-data-grid> to process large datasets without UI lag.
• Table & Plain Text Views: Interactively toggle between polished grid views and raw plain text instantly.
• Robust Editing:
  • Right-click Context Menus with specialized Row, Column, and Header operations.
  • Insert Row Above / Below.
  • Insert Column Left / Right.
  • Delete Rows and Columns instantly.
  • Edit Headers natively to restructure schema properties asynchronously.
• Read-Only Mode: Default active safeguard to prevent accidental destructive actions, with an overriding Edit Mode checkbox.
• Auto-Detection: Automatically detects file encoding (UTF-8, Windows-1252, etc.) and delimiters (comma, tab, pipe, semicolon).
• Sticky Headers: Scroll through thousands of records while keeping your column schema actively pinned to the top of the viewport.
• Resizable Columns: Header columns support drag-and-drop horizontal resizing which dynamically aligns to the memory widths.
• Hover & Focus Tuning: Employs Excel-style row highlighting and strict single-cell focus selection for superior readability.

Usage

Simply open any .csv or .tsv file to automatically load it in the Power CSV editor!

1. Select Table to view it conceptually, or Plain Text to inspect the true raw string delimiters.
2. Check Edit Mode to unlock right-click editor functionality.
3. Once edits are made, hit Save Changes or Cmd+S / Ctrl+S to flush the parsed state natively back to the disk formatting automatically.
