• Or mentions wanting to format/prettify JSON data

Tool Location

Symlinked to ~/.local/bin/json-pretty for PATH access.

Usage

# From file
json-pretty input.json

# From stdin/pipe
cat data.json | json-pretty
echo '{"foo":"bar"}' | json-pretty

# Save to file
json-pretty input.json -o output.json

# Options
json-pretty input.json --indent 4      # Custom indentation
json-pretty input.json --sort-keys     # Sort object keys
json-pretty input.json --compact       # Minify instead of prettify

Options

• -o, --output FILE: Write to file instead of stdout
• -i, --indent N: Indentation spaces (default: 2)
• -s, --sort-keys: Sort object keys alphabetically
• -c, --compact: Compact output (minify)

Examples

Prettify inline JSON:

echo '{"name":"cal","items":[1,2,3]}' | json-pretty

Format a file:

json-pretty messy.json -o clean.json

Sort keys and use 4-space indent:

json-pretty data.json --indent 4 --sort-keys

Privacy Note

Built specifically to avoid posting potentially sensitive JSON to online prettifier services.
