About jo
jo creates JSON from the shell without hand-writing quotes and braces. You pass key=value pairs and it prints a JSON object, detecting numbers and booleans automatically; it can also turn lines of piped input into a JSON array, and pretty-print output with -p.
It is useful in shell scripts that need to send JSON to an API or feed it to jq, and it ships with bash and zsh completions and a man page.
Strengths
- Builds valid JSON without manual quoting
- Detects numbers and booleans automatically
- Works well in pipelines with jq
- Shell completions for bash and zsh
Limitations
- Only creates JSON, does not query or transform it
- Development is infrequent
