# JWK_TO_PEM

*[View on tines.com](https://www.tines.com/docs/formulas/functions/jwk-to-pem/)*

Converts a JSON Web Key (JWK) to PEM format. By default returns the public key in PEM format. When `include_private` is `TRUE`, returns the private key in PEM format if available. Only supports RSA and ECDSA keys.

**Categories:** Data Parsing/Conversion

## Syntax

```
JWK_TO_PEM(jwk, [include_private: FALSE])
```

## Examples

### Example 1

Input:

```json
{
  "my_action": {
    "jwk": {
      "kty": "RSA",
      "n": "0vx7agoebGcQSuuPiLJXZptN9nndrQmbXEps2aiAFbWhM78LhWx4cbbfAAtVT86zwu1RK7aPFFxuhDR1L6tSoc_BJECPebWKRXjBZCiFV4n3oknjhMstn64tZ_2W-5JsGY4Hc5n9yBXArwl93lqt7_RN5w6Cf0h4QyQ5v-65YGjQR0_FDW2QvzqY368QQMicAtaSqzs8KJZgnYb9c7d0zgdAZHzu6qMQvRL5hajrn1n91CbOpbISO_BIZ1tOl6U7QElTqLaXyJjnfwJTQwKPUwD3xQGNzqXPv2VZKtlkPKhEjRXN9YXJnS9QsQFRU5L2rN2tOXJm4a-BsxoYPAmCl1h",
      "e": "AQAB"
    }
  }
}
```

Formula:

```
JWK_TO_PEM(my_action.jwk)
```

Output:

```json
