Encounter: Visidata

A terminal interface for exploring and arranging tabular data.

https://www.visidata.org/

Short review

Wired:

• Very fast on big datasets
• Easily get the data overview hitting Shift+I (hide irrelevant columns using “-“)
• Reformatting dates by using regexs (for grouping by day, month etc.)
• Quickly get an aggregation by choosing a method and hitting Shift+F (hide other columns)

Tired:

• UI, or lack thereof
• Specifying the delimiter in the command line when invoking the tool
