Commands
# Pretty-print (from file or stdin)
python3 scripts/jsonpretty.py data.json
echo '{"a":1}' | python3 scripts/jsonpretty.py
# Validate JSON
python3 scripts/jsonpretty.py --validate data.json
# Query with dot-notation
echo '{"user":{"name":"Rogue"}}' | python3 scripts/jsonpretty.py -q "user.name"
# Flatten nested JSON
cat data.json | python3 scripts/jsonpretty.py --flat
# Structure stats (key count, depth, types, size)

# Sort keys
python3 scripts/jsonpretty.py --sort data.jsonFeatures
- Pretty-print with 2-space indent (default)
- JSON validation with error messages
- Dot-notation querying (supports array indices:
key[0].sub) - Flatten nested objects to
key.subkey = valuepairs - Structure statistics: key count, nesting depth, type distribution, byte size
- Compact/minify mode
- Sorted key output
- Reads from file or stdin
