I need one help to convert json data into dataframe. Could you please help me how to do this?

Example:

JSON DATA

```
{
    "user_id": "vmani4",
    "password": "*****",
    "api_name": "KOL",
    "body": {
      "api_name": "KOL",
      "columns": [
        "kol_id",
        "jnj_id",
        "kol_full_nm",
        "thrc_cd"
      ],
      "filter": {
        "kol_id": "101152",
        "jnj_id": "7124166",
        "thrc_nm": "VIR"

      }
    }
}

```

Desirable output:

```
user_id     password       api_name     columns       filter     filter_value
vmani        ******         KOL          kol_id       kol_id       101152
                                         jnj_id       jnj_id       7124166
                                         kol_full_nm  thrc_nm      VIR
                                         thrc_cd

```
