JSON Transform CLI

Transform JSON like a pro. jq-alternative for Node.js developers.

Query. Reshape. Flatten. Diff. Convert.

Quick Start

bash
npm install -g @lxgicstudios/jsonmorph
bash
# Extract field
jsonmorph '.users[].name' data.json

# Transform structure
jsonmorph '{names: .users[].name, count: .users | length}' data.json

# Flatten nested JSON
jsonmorph flatten deep.json

What It Does

Query

  • •jq-like syntax
  • •Deep property access
  • •Array operations
  • •Filtering and mapping

Transform

  • •Reshape objects
  • •Rename keys
  • •Type conversion
  • •Computed fields

Utilities

  • •Flatten/unflatten
  • •Diff two JSONs
  • •Merge objects
  • •Schema extraction

Commands

bash
# Query with path
jsonmorph '.data.items[0].name' file.json

# Filter array
jsonmorph '.users | filter(.age > 25)' file.json

# Map array
jsonmorph '.items | map({id, title})' file.json

# Flatten nested object
jsonmorph flatten nested.json

# Diff two files
jsonmorph diff old.json new.json

# Merge objects
jsonmorph merge base.json override.json

# Extract schema
jsonmorph schema data.json

Piping Support

bash
# From API response
curl https://api.example.com/data | jsonmorph '.results'

# Chain transforms
cat data.json | jsonmorph '.items' | jsonmorph 'map(.name)'

Why jsonmorph?

  • •JavaScript-native - No need to learn jq syntax
  • •Familiar - Uses JS-like expressions
  • •Fast - Streaming support for large files
  • •No deps - Pure Node.js
