It's "less" for your data!
ngrid is a tool for interactive browsing large tabular datasets in a text-based terminal enviroment. ngrid is to tables as less is to text.
pip install git+https://github.com/twosigma/ngrid
The ngrid
command reads CSV data from a file, or from standard input if no
filename is specified, and displays it in an interactive, ncurses-based grid.
By default, ngrid loads rows incrementally from its input, so that it can quickly present the beginning of a long file or stream without loading the entirety of the data. (The total line count in the status bar shows "+" to indicate that more lines are available but have not been read.) It does however store all data it has already seen, so that you can always scroll backward.
With the --dataframe
option, ngrid
instead loads the entire input into a
Pandas dataframe at startup. This may result in better guesses for column
display parameters, such as width and decimal precision.
In the interactive display, press h
to show usage help; press q
to exit.
Use ngrid.grid.show_dataframe()
to show a Pandas dataframe. As with the
command line program, press q
to exit the interactive display and return
control.
ngrid works only in an ncurses-compatible terminal; it won't work in IPython Notebook, most IDEs, or similar graphical environments.
