VisiData is a tool that lets you quickly open, explore, summarize, and analyze datasets in your computer’s terminal. It combines the clarity of a spreadsheet, the efficiency of the terminal, and the power of Python, into a lightweight utility which can handle millions of rows with ease.
VisiData works with CSV files, Excel spreadsheets, SQL databases, and many other data sources.
VisiData features in our 100 Great and Must-Have CLI Linux Applications compilation.
This is free and open source software.
Features include:
- Explore, clean, edit, and restructure data. Rows can be selected, filtered, and grouped.
- Fast, opening files of several tens of megabytes almost instantly.
- Agile, the software makes it easy to search, filter, sort, join and restructure tabular data.
- Obtain an overview of the datasets you want to work on in just a few steps.
- Instant histogram with one keystroke.
- Scatterplots in the terminal – visualise the relationship between numeric dependent variables vs a numeric independent variable. Optionally, a second independent variable, which is categorical, adds an additional colored scatter plot for each category.
- Opens many of the typical structured text formats (csv, tsv, xlsx, xls, json, xml, sqlite, shp, html, hdf5, xpt, sas7bdat, sav, dta).
- Use only from the keyboard; forget about the mouse.
- Columns can be rearranged, transformed, and derived via regex or Python expressions.
- Workflows can be saved, documented, and replayed.
