JSON Modifier
A utility for modifying JSON files using RFC 6902 JSON Patch format. Supports precise additions, removals, replacements, moves, copies, and tests.
Usage
# Modify a file in place
node skills/json-modifier/index.js --file path/to/config.json --patch '[{"op": "replace", "path": "/key", "value": "new_value"}]'
# Modify and save to a new file
node skills/json-modifier/index.js --file input.json --patch '[...]' --out output.json
# Use a patch file
node skills/json-modifier/index.js --file input.json --patch-file patches/update.json
Patch Format (RFC 6902)
The patch must be a JSON array of operation objects.
Examples
Replace a value:
[
{ "op": "replace", "path": "/version", "value": "2.0.0" }
]
Add a new key:
[
{ "op": "add", "path": "/features/new_feature", "value": true }
]
Remove a key:
[
{ "op": "remove", "path": "/deprecated_key" }
]
Append to an array:
[
{ "op": "add", "path": "/list/-", "value": "item" }
]
Safety
- Validates patch against document before applying.
- Atomic write (writes to temporary file, then renames).
- Preserves indentation (default: 2 spaces).
