Merge JSON objects using jq

2023-05-26 · Thomas Taylor

Merging objects in jq is handled natively since 1.14.

Merge objects using `jq`

Given a file named example.json

1{
2    "key": "value1",
3    "anotherKey": "value2",
4    "oneMoreKey": "value3"
5}

and another file named example2.json,

1{
2  "key1": "value2",
3  "key2": "value3",
4  "key4": "value4"
5}

merging the two objects can be completed using:

1jq -s '.[0] * .[1]' example.json example2.json

Output:

1{
2  "key1": "value2",
3  "key2": "value3",
4  "key4": "value4",
5  "key": "value1",
6  "anotherKey": "value2",
7  "oneMoreKey": "value3"
8}
