Tidy Viewer (tv) is a cross-platform csv pretty printer that uses column styling to maximize viewer enjoyment.
tv
The following install options are available
.deb
installThe following will install from the crates.io source. For convenience add the alas alias tv='tidy-viewer'
to bashrc.
cargo install tidy-viewer
sudo cp /home/$USER/.cargo/bin/tidy-viewer /usr/local/bin/.
echo "alias tv='tidy-viewer'" >> ~/.bashrc
source ~/.bashrc
The below instructions work with the most recent release <VERSION>
found here release page.
wget https://github.com/alexhallam/tv/releases/download/<VERSION>/tidy-viewer_<VERSION>_amd64.deb
sudo dpkg -i tidy-viewer_<VERSION>_amd64.deb
echo "alias tv='tidy-viewer'" >> ~/.bashrc
source ~/.bashrc
Kindly maintained by @yigitsever
paru -S tidy-viewer
We currently cut releases for the following architectures. Download from the release page.
The instuctions for all of the above are very similar with the following general steps.
tar -xvzf <RELEASE_FILE_NAME>
cd
into uncompressed foldertidy-viewer
After the above steps I would highly reccomend you make an alias for tidy-viewer
as shown for other builds.
sudo snap install --edge tidy-viewer
tidy-viewer --help
brew tap alexhallam/tidy-viewer
brew install tidy-viewer

The first three digits represent > 99.9% the value of a number. -- GNU-R Pillar
tv
uses the same significant figure (sigfig) rules that the R package pillar
uses.
The purpose of the sigfig rules in tv
is to guide the eye to the most important information in a number. This section defines terms and the decision tree used in the calculation of the final value displayed.

fractional digit(s)
fractional digits: Digits on the rhs of the decimal. The represent the non-integer part of a number.
There are only 4 outputs possible. The significant figures to display are set by the user. Assume sigfig = 3
:
12345.0 -> 12345
): If no fractional digits are present and lhs >= sigfig then return lhs1234.5 -> 1234.
): If fractional digits are present and lhs >= sigfig then return lhs with point. This is to let the user know that some decimal dust is beyond the main mass of the number.1.2345 -> 1.23
): If fractional digits are present and lhs < sigfig return the first three digits of the number.0.00001 -> 0.00001
): This is reserved for values with leading 0s in the rhs.# Psuedo Code: Sigfig logic assuming sigfig = 3
if lhs == 0:
n = ((floor(log10(abs(x))) + 1 - sigfig)
r =(10^n) * round(x / (10^n))
return r
// (0.12345 -> 0.123)
else:
if log10(lhs) + 1 > sigfig:
if rhs > 0:

tv
is a good compliment to command line data manipulation tools. I have listed some tools that I like to use with tv.
xsv - Command line csv data manipulation. [Rust | CLI]
csvtk - Command line csv data manipulation. [Go | CLI]
tsv-utils - Command line csv data manipulation toolkit. [D | CLI]
q - Command line csv data manipulation query-like. [Python | CLI]
miller - Command line data manipulation, statistics, and more. [C | CLI]
VisiData - An interactive terminal user interface that is built to explore and wrangle data. [Python | TUI]
column
Comes standard with linux. To get similar functionality run column file.csv -ts,
Though column
is similar I do think there are some reasons tv
is a better tool.
NA
values are very important! Viewers should have their attention drawn to these empty cells. In the image below NA
values are not only invisible, but it seems to be causing incorrect alignment in other columns.
There are many ways that programs will designate missing values. Some use none
, others use NaN
, and many more ""
, NA
, null
, n/a
etc. tv
searches for these strings and replaces them with NA
. This is similar in spirit to the significant digit calculations and the truncation of columns with long strings. The purpose of tv
is not to show the complete literal value, but to guide the eye.
In cases where the terminal width can't fit all of the columns in a dataframe, column will try to smush data on the rows below. This results in an unpleasant viewing experience.
tv
can automatically tell when there will be too many columns to print. When this occurs it will only print the columns that fit in the terminal and mention the extras in the footer below the table.
For information on dotfile configuration see tv --help
. This allows users to set their own color palette, rows to print, max column width, etc.

Tidy Viewer (tv) is a csv pretty printer that uses column styling to maximize viewer enjoyment.✨✨��✨✨
Example Usage:
wget https://raw.githubusercontent.com/tidyverse/ggplot2/master/data-raw/diamonds.csv

Configuration File Support:
An example config is printed to make it easy to copy/paste to `tv.toml`.
The config (tv.toml) location is dependent on OS:
* Linux: $XDG_CONFIG_HOME or $HOME/.config/tv.toml
* macOS: $HOME/Library/Application Support/tv.toml
* Windows: {FOLDERID_RoamingAppData}\tv.toml
## ==Tidy-Viewer Config Example==
## Remove the first column of comments for valid toml file
## The delimiter separating the columns. [default: ,]
#delimiter = ","
## Add a title to your tv. Example 'Test Data' [default: NA ("")]
#title = ""
## Add a footer to your tv. Example 'footer info' [default: NA ("")]
#footer = ""
## The upper (maxiumum) width of columns. [default: 20]
#upper_column_width = 20
## The minimum width of columns. Must be 2 or larger. [default: 2]
#lower_column_width = 2
## head number of rows to output <row-display> [default: 25]
#number = 35
## meta_color = [R,G,B] color for row index and "tv dim: rowsxcols"
#meta_color = [64, 179, 162]
## header_color = [R,G,B] color for column headers
#header_color = [232, 168, 124]
## std_color = [R,G,B] color for standard cell data values
#std_color = [133, 205, 202]
## na_color = [R,G,B] color for NA values
#na_color = [226, 125, 95]
USAGE:
tidy-viewer [FLAGS] [OPTIONS] [FILE]
FLAGS:
-d, --debug-mode Print object details to make it easier for the maintainer to find and resolve bugs.
-h, --help Prints help information
-V, --version Prints version information
OPTIONS:
-c, --color <color>
There are 5 preconfigured color palettes:
(1)nord
(2)one_dark
(3)gruvbox
(4)dracula
(5)uncolor (Coming Soon)
An input of (5)uncolor will remove color properties. Note that colors will make it difficult to pipe output
to other utilities.The default value of (0) is reserved to make config/option coloring logic easier.
[default: 0]
-s, --delimiter <delimiter> The delimiter separating the columns. [default: ,]
-f, --footer <footer> Add a footer to your tv. Example 'footer info' [default: NA]
-l, --lower-column-width <lower-column-width>
The lower (minimum) width of columns. Must be 2 or larger. [default: 2]
-n, --number of rows to output <row-display> Show how many rows to display. [default: 25]
-t, --title <title> Add a title to your tv. Example 'Test Data' [default: NA]
-u, --upper-column-width <upper-column-width> The upper (maxiumum) width of columns. [default: 20]
