     VisiData — a terminal utility for exploring and arranging tabular data

     vd [options] [input ...]
     vd [options] --play cmdlog [-w waitsecs] [--batch] [-i] [-o output] [field=value]
     vd [options] [input ...] +toplevel:subsheet:col:row

     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.

     -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)
     -i, --interactive       launch VisiData in interactive mode after batch
     -o, --output=file       save final visible sheet to file as .tsv
     field=value             replace "{field}" in cmdlog contents with value

   Commands During Replay

   Data Visualization

     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).

     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 ).

           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

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