# jsondup

[![build](https://github.com/jar-b/jsondup/actions/workflows/build.yml/badge.svg)](https://github.com/jar-b/jsondup/actions/workflows/build.yml)

Detect duplicate keys in a JSON object.

## Installation

```console

go install github.com/jar-b/jsondup/cmd/jsondup@latest

```

## Usage

```console

$ jsondup -h

Detect duplicate keys in a JSON object.

Usage: jsondup [filename]

```

## Examples

### Simple

Given the following content in `dup.json`:

```json

{

  "a": "foo",

  "a": "bar"

}

```

```console

$ jsondup dup.json

2023/09/12 15:53:29 duplicate key "a"

```

### Nested

A more complex example might be an AWS IAM policy document with duplicated `Condition` keys:

```json

{

  "Version": "2012-10-17",

  "Statement": [

    {

      "Effect": "Allow",

      "Action": "s3:PutObject",

      "Resource": "*",

      "Condition": {

        "StringEquals": {

          "s3:prefix": ["one/", "two/"]

        },

        "StringEquals": {

          "s3:versionid": "abc123"

        }

      }

    }

  ]

}

```

```console

$ jsondup iam.json

2023/09/12 15:57:15 duplicate key "Statement.0.Condition.StringEquals"

```
