VisiData is an easy-to-use multipurpose tool to explore, clean, edit, and restructure data. Rows can be selected, filtered, and grouped; columns can be rearranged, transformed, and derived via regex or Python expressions; and workflows can be saved, documented, and replayed.

Replay Mode

-p, --play=cmdlog: replay a saved cmdlog within the interface
-w, --replay-wait=seconds: wait seconds between commands
-b, --batch: replay in batch mode (with no interface)
-o, --output=file: save final visible sheet to file as .tsv
--replay-movement: toggle --play to move cursor cell-by-cell
field=value: replace "{field}" in cmdlog contents with value

Commands During Replay

^U: pause/resume replay
^N: execute next row in replaying sheet
^K: cancel current replay

Files

At the start of every session, VisiData looks for $HOME/.visidatarc, and calls Python exec() on its contents if it exists. For example:

   options.min_memory_mb=100  # stop processing without 100MB free

   bindkey('0', 'go-leftmost')   # alias '0' to go to first column, like vim

   def median(values):
       L = sorted(values)
       return L[len(L)//2]

   aggregator('median', median)

Functions defined in .visidatarc are available in python expressions (e.g. in derived columns).

Supported Sources

Core VisiData includes these sources:

tsv (tab-separated value)

Plain and simple. VisiData writes tsv format by default. See the --tsv-delimiter option.

csv (comma-separated value)

.csv files are a scourge upon the earth, and still regrettably common.
