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]

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 a saved cmdlog within the interface wait seconds between commands replay in batch mode (with no interface) save final visible sheet to file as .tsv
--replay-movement
    toggle --play to move cursor cell-by-cell
field=value

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]
       vd.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.

In addition, .zip, .gz, .bz2, .xz, ,zstd, and .zst files are decompressed on the fly.
