Loading data

How to specify a source

In VisiData, loaders load files of a particular type. These sources are currently supported.

On default, the file extension determines which loader is used. Unknown filetypes are loaded as Text sheets.

vd sample.tsv
ps aux | vd

To force a particular loader, pass -f with the filetype or format name.

vd -f sqlite bar.db
ls -l | vd -f fixed

How to load multiple datasets simultaneously

Multiple files can be passed as inputs through the commandline.

vd birdsdiet.tsv surveys.csv sunshinelist.html

Upon launching, the last dataset to load (in this case, sunshinelist.html) will be displayed on top.

To load another file, press o and enter a filepath.

How to access other loaded or derived sheets:

  1. Press S to open the Sheets sheet.
  2. Move the cursor to the row containing the desired sheet.
  3. Press Enter to jump to the sheet referenced in that current cursor row.

How to convert a dataset from one supported filetype into another

vd -b countries.fixed -o countries.tsv

Note: Not all filetypes which are supported as loaders are also supported as savers. See the manpage for the supported output formats.
