Working With Large Cells¶
Sometimes, values in a dataset are too large to display entirely in a single row. VisiData provides a few ways to view these large cells:
- Multiline mode
- Scrolling within cells
- Diving into cells
In the examples below, we’ll examine the REMARKS column of the FAA dataset:

Enabling multiline mode¶
By default, VisiData displays each row on a single line. You can switch to multiline mode (and toggle back out of it) by pressing v. Here’s what that looks like:
File Edit View Column Row Data Plot System Help | VisiData 3.0.2 | Alt+H for help men <PERSON │ REMAINS_COLLECTED │ REMARKS Tower │ 0 │ N9240F was right base to final on Runway 4, and he reported a bird ║ strike to the left wing.

Note
The default row height in multiline mode is 4 lines, but you can adjust this through VisiData’s default_height setting.
Scrolling within cells¶
To see more of a cell in single-line mode, you can scroll back and forth within a column using the following commands:
| Keystrokes | Action |
|---|---|
| zh | Scroll text left |
| zl | Scroll text right |
| zj | Scroll text down |
| zk | Scroll text up |
| gzh | Scroll back to leftmost character |
| gzk | Scroll back to topmost character |
Here’s how it looks in practice, starting with the same view as above:

Diving into cells¶
Pressing z + Enter “dives” into your current cell, opening a “Text Sheet” that contains only that cell’s value:
File Edit View Column Row Data Plot System Help | VisiData 3.0.2 | Alt+H for help men text N9240F was right base to final on Runway 4, and he reported a bird strike to the left wing. He d… 2› faa-wildlife-strikes[0].REMARKS| zEnter 1 lines
If your cell’s value contains newlines, they’ll appear as such in the Text Sheet. From a Text Sheet, you also can press Control-o to open the cell in your terminal’s default text editor.
Tip
Similarly, whenever you’re editing a cell within VisiData (i.e., via the e command), you can also run Control-o to open that cell in your terminal’s default text editor.
