JSON Formatter

Format, minify, and validate JSON data. Use when you need to pretty-print JSON, compact JSON for transport, verify JSON syntax, or process JSON from files or stdin.

Format, minify, and validate JSON with a single script.

Quick Reference

bash

# Format (pretty-print)
python3 scripts/json_tool.py format [file] [--indent 2]

# Minify (remove whitespace)
python3 scripts/json_tool.py minify [file]

# Validate (check syntax only)
python3 scripts/json_tool.py validate [file]

If file is omitted, reads from stdin.

Examples

bash

# Format a file
python3 scripts/json_tool.py format config.json --indent 4

# Minify a file and save
python3 scripts/json_tool.py minify data.json > min.json

# Validate stdin
echo '{"a":1}' | python3 scripts/json_tool.py validate

# Pipe through format
cat api-response.json | python3 scripts/json_tool.py format
