CSV Edit

Edit delimited text as a spreadsheet without leaving Visual Studio Code.

CSV Edit opens CSV, TSV, TAB, and PSV files in a compact grid by default. The underlying document stays plain text, so normal saving, source control, diffs, and VS Code undo history continue to work. Processing is local-only.

CSV Editは、区切り形式のテキストをVS Code上で表として編集するための ローカル完結型エディターです。

An independent rewrite

This repository is a GitHub fork of jonaraphael/csv, retained so that the project's origin and MIT attribution remain visible.

CSV Edit is a complete product and codebase rewrite. Its implementation, architecture, interface copy, documentation, icon, and Marketplace presentation were newly created for CSV Edit. The upstream project's README prose, screenshots, and Marketplace artwork are not reused.

What it does

• Opens .csv, .tsv, .tab, and .psv files directly in a grid
• Edits cells, ranges, rows, and columns with keyboard or mouse
• Copies and pastes tabular data in an Excel-compatible format
• Inserts, removes, resizes, and reorders rows and columns
• Sorts columns, filters visible rows, and searches or replaces values
• Trims, changes case, fills blanks, and removes empty or duplicate rows
• Previews bulk changes before applying them as one undoable operation
• Reports uneven rows, empty headers, and duplicate headers
• Preserves BOM, line endings, delimiters, quoted values, and multiline cells
• Loads large documents in chunks and bounds expensive inference work

Grid or text—your choice

Select Text in the grid, use the editor-title action, or run CSV Edit: Toggle Grid/Text View. CSV Edit remembers the last selection globally and uses it when the next supported file opens.

Run CSV Edit: Set Theme to choose Auto, Light, or Dark. This preference affects only CSV Edit; Auto follows the active VS Code theme.

File handling and privacy

CSV Edit does not send document contents to a server. Parsing, editing, filtering, transformation, and validation happen on your machine. Display state such as column widths, filters, scroll position, and theme choice is stored in VS Code state rather than written into the CSV file.

Support development

If CSV Edit saves you time, you can sponsor its continued development. Sponsorship supports maintenance, accessibility, performance work, and new releases.

Requirements

• Visual Studio Code 1.130 or newer
• Windows, macOS, or Linux

Build from source

npm ci
npm run verify
npm run package

The package command produces a .vsix that can be installed from VS Code.
