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:
<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. He did not need any assistance. ║ He landed and taxied to the ramp, and said there was only ║ minor damage done to the left wing. ║ Tower | 0 | ON FINAL, PILOT REPORTED HEARING IMPACT. AFTER LANDING AND ║ INSPECTING AIRCRAFT, PILOT DISCOVERED DENT IN TIRE BOOT. UPON ║ RUNWAY INSPECTION A BIRD CARCASS WAS FOUND ON RUNWAY NORTH OF ║ TAXIWAY DELTA. ║ Tower | 0 | N952G, P46T/G, bird strike, no injuries reported, damage to ║ vortex generator, pilot's name is Robert Nipper, 713-539-0797. ║ Tower | 0 | NO EMERGENCY: AFTER THE AIRCRAFT WAS AT THE GATE THE PILOT OF ║ DAL939 ADVISED THAT THEY HAD A BIRD STRIKE ON A 2 MILE FINAL ║ TO RWY30R. A BIRD STRUCK THE RIGHT WING AND THE LANDING LIGHT. ║ THE LANDING LIGHT WAS SHATTERED AND THERE WAS NO DAMAGE ON THE ║ RIGHT ║ Tower | 0 | MEDFLY1, A BE9L, VFR, LANDED RY 15. UPON CONTACTING GC, PILOT ║ ADVISED HE HAD EXPERIENCED A BIRD STRIKE AND REQUESTED ║ INSTRUCTIONS TO TAXI TO THE RAMP TO INSPECT THE ACFT. THE ║ PILOT CALLED THE TOWER AND ADVISED THE THAT THE AIRCRAFT HAD ║ LIGHT DAMAGE TO THE ║ Tower | 0 | DAL571 EXPERIENCED A BIRD INGESTION ON ARRIVAL TO STT ON JULY ║ 17. THE PILOT DID NOT REPORT A BIRD STRIKE TO THE ATCT. THE ║ ATCT DID NOT FIND OUT ABOUT THE BIRD STRIKE UNTIL THE FOLLOWIN…║rows
Note
By default, the maximum row height is 10 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:
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| z^J 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.
