CSV Editor

The CSV Editor in DevKnife gives you a simple way to work with comma-separated values without opening a spreadsheet app or uploading data to an online tool. Open an existing CSV file or start a new sheet, inspect it in a table view, edit cells directly, and save your changes back to disk.

Key Features

Section titled “Key Features”
  • Table-based editing – work with CSV data in a native table view instead of raw plain text.
  • File operations – create a new CSV file, open an existing file, save changes, and use Save As when needed.
  • Row management – insert rows above or below the current row, append new rows, and delete rows from the context menu.
  • Column management – insert columns on the left or right, rename columns, and delete columns directly from the header menu.
  • Unsaved draft support – drafts are preserved per window, so you can leave the tool and come back without losing work.
  • Dirty state tracking – DevKnife shows when the current document has unsaved changes.

Working with CSV Files

Section titled “Working with CSV Files”

You can open CSV files directly from the toolbar or from the File menu. When you create a new file, DevKnife starts with a small blank sheet so you can begin editing immediately.

The editor is designed for practical CSV work:

  • edit cell values in place
  • move through the table quickly
  • add or remove rows and columns as needed
  • keep the structure readable even for larger files

Row and Column Actions

Section titled “Row and Column Actions”

The CSV Editor includes context menus for the two main structural operations:

  • Row actions are available from the table body and let you insert or delete rows.
  • Column actions are available from the header and let you insert, rename, or delete columns.

This makes it possible to reshape CSV data without dropping down to raw text editing.

Saving and Drafts

Section titled “Saving and Drafts”

When you edit a CSV file, DevKnife tracks unsaved changes and lets you save them back to the original file or to a new location.

If you are working on a draft and switch to another DevKnife tool, the current CSV state is preserved for that window and restored when you return. This makes the CSV Editor suitable for quick edits as well as longer editing sessions.

Privacy

Section titled “Privacy”

The CSV Editor works entirely offline on your Mac. Your CSV files are never uploaded or sent to external services.
