LanceDB Explorer
Browse LanceDB databases and tables directly inside VS Code.
Features
Open any local LanceDB database from the sidebar and browse its tables in a tree view.
View table data in a paginated, resizable grid (powered by Tabulator).
Column type hints, row numbers, hover tooltips for full cell content, and one-click copy to clipboard.
Edit cell values — click the pencil icon to edit in a modal, including JSON editing for list/vector columns. Values are validated against the column's type before saving.
Clear a cell to null with one click, on any nullable column.
Delete a row via the row-number column, with a Cancel/Delete confirmation prompt since it can't be undone.
Pin rows to keep them visible above the current page regardless of sorting, filtering, or pagination.
Sort by column — pushes a real ORDER BY to LanceDB (not just a local re-sort of the current page), so it's consistent across pagination.
Filter by column — case-insensitive text/number/boolean matching, pushed to LanceDB as a WHERE clause; matches update the row count and pagination too.
Pin columns to keep them visible while scrolling horizontally; multiple pinned columns stack side by side at the left edge.
Matches your VS Code theme automatically (light, dark, and high-contrast).
Usage
Open the Command Palette and run LanceDB: Open Database... , then select a LanceDB database directory.
Expand the database in the LanceDB view (Activity Bar) → Tables to see the tables it contains.
Click a table to open it in a data grid. Use the toolbar at the bottom to page through rows.
Hover a cell for copy/edit/clear actions, or hover a row number for pin/delete. Hover a column header for sort, filter, and pin controls.
Development
npm install<br>npm run watch # rebuild the extension and webview bundles on change
