SYNOPSIS

rsv *command* [*options*] [*file*]

DESCRIPTION

rsv is a Rust command-line tool for inspecting and transforming CSV, TXT, and Excel files. It emphasizes speed (Rayon parallel processing where marked), progress bars on long jobs, and pipeline-friendly subcommands.Commands include head, tail, header/headers, count, estimate, clean, unique, frequency, split, select, flatten, slice, search, sort, sample, stats, excel2csv, to (export), and table. Most commands can be chained except clean and excel2csv. Excel defaults to the first sheet; use --sheet where supported.Install from GitHub releases (add the binary to PATH). Use rsv *command* --help for flags.

PARAMETERS

head / tail [-n *n*] [*file*]

Preview first/last rows (default 10).
headers [-s *sep*] [*file*]
Print column headers.
count / estimate [*file*]
Exact or fast approximate line counts.
frequency / stats / unique / select / search / sort / sample / split / slice / flatten
Analysis and reshaping (several support parallel processing and progress bars).
excel2csv / to / table / clean
Convert, export, format, or clean fields.

INSTALL

yay -S rsv
copy

CAVEATS

sort is in-memory and limited (at most two columns per upstream docs). Very wide or huge Excel sheets may need more RAM. Confirm separator flags for TSV/non-CSV text.
