NAME
VisiData — a terminal utility for exploring and arranging tabular data
SYNOPSIS
vd [options] [input ...]
vd [options] --play cmdlog [-w waitsecs] [--batch] [-o output] [field=value]
vd [options] [input ...] +toplevel:subsheet:col:row
DESCRIPTION
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

Data Visualization
. (dot) plot current numeric column vs key columns. The numeric key column is used for the x-axis;
categorical key column values determine color.
g. plot a graph of all visible numeric columns vs key columns.
If rows on the current sheet represent plottable coordinates (as in .shp or vector .mbtiles sources), .
plots the current row, and g. plots all selected rows (or all rows if none selected).
Canvas-specific Commands

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.
See the --csv-dialect, --csv-delimiter, --csv-quotechar, and --csv-skipinitialspace options.
Accepted dialects are excel-tab, unix, and excel.
fixed (fixed width text)
Columns are autodetected from the first 1000 rows (adjustable with --fixed-rows).
json (single object) and jsonl/ndjson/ldjson (one object per line).
Cells containing lists (e.g. [3]) or dicts ({3}) can be expanded into new columns with ( and
unexpanded with ).
sqlite
May include multiple tables. The initial sheet is the table directory; Enter loads the entire table
into memory. z^S saves modifications to source.
URL schemes are also supported:
http (requires requests); can be used as transport for with another filetype
For a list of all remaining formats supported by VisiData, see https://visidata.org/formats.
