Opens CSV, TSV, and other delimited files as a typed, searchable, filterable grid.
The image shows a synthetic sample file: 100,000 rows × 20 columns, 15 MB. The names, cities, and @example.com emails are not real. The Viewer pane on the right shows row 1 on the Record tab, as a read-only form.
- File types:
.csv,.tsv,.tab,.psv,.dsv,.ssv. The file opens in the "Table" viewer. - Grid and Code views. Grid is the table. Code shows the raw text in bb's source viewer.
- Large files. Only the rows on screen are in the page. With the 100,000-row sample, the first paint took 297–833 ms, and a search or filter change took 114 ms or less (bb web UI, headless Chrome).
- Delimiter: detected from
,tab;|. You can also pick one, or type any single character. - Header row: Auto, On, or Off. Auto shows its reason, for example "row 1 is text, rows 2+ are int in column 1".
- Typed columns: int, float, bool, date, or string, inferred from the first 1,000 rows. Numbers align right.
- Format: encoding (12 choices, UTF-8 by default), text qualifier (
",', none), decimal symbol (Auto,.,,), and date order (Auto, DMY, MDY, YMD). - Search in all columns, or only in the columns you pick. Case is ignored.
- Filters: add as many as you need. A row must match all of them. The operators follow the column type.
- Sort: click the arrow in a column name for ascending, descending, then off. Shift+click adds a column as the next sort level. The Sort panel sets the levels and their order.
- Columns: show or hide each column. Drag a column edge to resize it. Double-click the edge to fit the column to its content: the longest values in the rows you see, and the column name.
- Arrange columns: drag a column name left or right. A line shows where the column lands. The new order reaches the grid, Copy, Export, Save, and the Record tab. "Reset order" in the Columns panel puts the order of the file back.
- Select and copy, as in a spreadsheet: cells, rows, or columns. Copy gives tab-separated text, with or without the column names.
- Export: downloads the rows you see (search, filters, and sort applied) and the shown columns as a UTF-8 CSV file. The file on disk does not change.
- Save: writes the file itself. It asks first: overwrite the open file, or write a new file whose name you type. Save stays in the folder of the open file. It writes every row of the file, in file order, with the columns you see in the order you see, and it keeps the delimiter, the record delimiter, and the text qualifier of the file. It refuses when the file changed on disk after the plugin read it, and when the new name is already in use. The status bar shows "modified" until a Save writes the order you see.
- Viewer: a pane on the right of the grid or below it. A switch in the pane moves it, and the close button next to it closes the pane. Drag the edge of the pane to resize it, and double-click the edge for the default size. The plugin remembers the side and the size. The Cell tab shows the whole value of the active cell, with its line breaks and character count. The Record tab shows the active row as a read-only form: a label and a boxed value for each column. You can select and copy a value there. A long value scrolls inside its box. Its First, Previous, Next, and Last buttons sit above the form and stay in place while the form scrolls.
- Go to row: moves a row number to the top, marks it, and makes it the active row.
In Grid view. ⌘F, ⌘G, ⌘S, and ⌘C work anywhere in the plugin. ⌘C copies selected text first, if there is any, and a text box keeps its own copy. The other keys work after you click a cell.
| Key | Action |
|---|---|
| ⌘F / Ctrl+F | Focus Search |
| ⌘G / Ctrl+G | Focus Go to row |
| ⌘S / Ctrl+S | Export the rows you see as a CSV file |
| Arrows / Shift+arrows | Move the active cell / extend the selection |
| ⌘A / Ctrl+A | Select all |
| ⌘C / Ctrl+C | Copy the selection |
| Esc | Clear the selection |
| Shift+click a sort arrow | Add the column as a sort level; again: descending; again: remove it |

git clone https://github.com/laminko/bb-plugin-dsv.git
bb plugin build ./bb-plugin-dsv
bb plugin install "$PWD/bb-plugin-dsv" --yesThe build needs no npm install. --yes skips bb's confirmation. Plugins run as full-trust code inside the bb server.
npm install # dev dependencies: plugin SDK, React types, TypeScript
npm test # node --test logic.test.ts
npx tsc -p tsconfig.json # type check
bb plugin reload dsv # rebuild and reload the installed pluginnpm test uses Node's built-in TypeScript support (tested with Node 24.18). logic.ts holds the parser, detection, filters, sort, arrange, and copy logic, with no DOM. app.tsx is the viewer. server.ts holds the save rpc, which writes the file through the bb SDK.
- No cell editing. Save writes the column order and the columns you keep, not new values.
- The file loads once. It does not reload when the file changes on disk.
- Filters combine with AND only. No regular expressions.
- Save writes a file in thread storage only. A workspace file or a host file can be exported, not saved.
- Save writes UTF-8, and it leaves a hidden column out of the file.
- Closing the file tab does not ask about an order that is not written: bb gives a plugin no hook for that. Closing the browser tab does ask.
- Sort, column order, column widths, hidden columns, and the Viewer pane reset when the tab closes. Only the side and the size of the pane are kept.
NA,null, and thousands separators stay text. Time-zone offsets in dates are ignored.- The encoding is not detected. Pick it in Format.
