The rows in these duplicated sheets (except deepcopy) are references to rows on the original source sheets, and so edits to the filtered rows will naturally be reflected in the original rows. Use g' to freeze sheet contents in a deliberate copy. z' replace current column with a frozen copy, with all cells evaluated

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.
