space-table

This project is born from a desire to work with space-delineated tables in a programmatic way, for example the output of kubectl or a help message generated by envconfig. It parses fixed-width columnar text and can output in a variety of formats. When multiple rows of data are present, it assumes the first row is the header row. This will become the keys of outputted objects when outputting in JSON or YAML.

Supported Formats

• json
• yaml
• csv
• markdown

Installation

go install github.com/ryantate13/space-table@latest
