Transforming a list containing key/value strings with jq

Question

So, I basically have a file test.json

[
  "Name=TestName",
  "Tag=TestTag"
]

Which I'd like to transform into

[
  {
    "ParameterKey": "Name",
    "ParameterValue": "TestName",
  },
  {
    "ParameterKey": "Tag",
    "ParameterValue": "TestTag",
  }
]

With jq. Any idea?

I tried a lot, trust me. `cat test.json | jq .[] | [.ParameterKey, .ParameterValue]` .... — Mornor, May 12 '20 at 12:25

See How to create a [Minimal, Reproducible Example](https://stackoverflow.com/help/minimal-reproducible-example). It also very helpful to show in your Question an expected result, and quote any (exact) errors you are getting. — Ron, May 12 '20 at 12:33

You don't need to use split() call twice but just once and access the results directly with the Array/Object Value Iterator: .[] and specifying the index inside

jq -n '[ inputs[] | split("=") | {ParameterKey: .[0], ParameterValue: .[1]} ]'

You can try JQ Play

I tried with the following jq. It should work as long as you are sure of the format of the array.

[.[] | {ParameterKey: split("=")[0], ParameterValue: split("=")[1]}]

If you are using from terminal, you can use the following option

cat test.json | jq '[.[] | {ParameterKey: split("=")[0], ParameterValue: split("=")[1]}]'

You really don't need `cat`. Redirect input of `jq` directly with ` – Léa Gris May 12 '20 at 12:36
