TSV Preview

Read-only TSV preview for VS Code.

TSV Preview opens .tsv files in a custom preview that:

• skips # comment lines when rendering tabular data
• renders the first data row as table headers
• preserves comments in a separate section
• lets you switch between table view and raw TSV text

Features

• secure webview rendering with CSP and escaped HTML
• refreshes when the source document changes
• lightweight bundled extension with no runtime dependencies

Usage

1. Open a .tsv file in VS Code.
2. Right click the file and choose Open With....
3. Select TSV Preview.
4. If you want, configure it as the default editor for .tsv files.
5. Start using it.
6. Use the toggle button in the top-right corner to switch between table view and raw TSV view.
