| # `jsonencode` Function |
| |
| `jsonencode` encodes a given value to a string using JSON syntax. |
| |
| The JSON encoding is defined in [RFC 7159](https://tools.ietf.org/html/rfc7159). |
| |
| This function maps |
| [Terraform language values](/language/expressions/types) |
| to JSON values in the following way: |
| |
| | Terraform type | JSON type | |
| | -------------- | --------- | |
| | `string` | String | |
| | `number` | Number | |
| | `bool` | Bool | |
| | `list(...)` | Array | |
| | `set(...)` | Array | |
| | `tuple(...)` | Array | |
| | `map(...)` | Object | |
| | `object(...)` | Object | |
| | Null value | `null` | |
| |
| Since the JSON format cannot fully represent all of the Terraform language |
| types, passing the `jsonencode` result to `jsondecode` will not produce an |
| identical value, but the automatic type conversion rules mean that this is |
| rarely a problem in practice. |
| |
| When encoding strings, this function escapes some characters using |
| Unicode escape sequences: replacing `<`, `>`, `&`, `U+2028`, and `U+2029` with |
| `\u003c`, `\u003e`, `\u0026`, `\u2028`, and `\u2029`. This is to preserve |
| compatibility with Terraform 0.11 behavior. |
| |
| The `jsonencode` command outputs a minified representation of the input. |
| |
| ## Examples |
| |
| ``` |
| > jsonencode({"hello"="world"}) |
| {"hello":"world"} |
| ``` |
| |
| ## Related Functions |
| |
| * [`jsondecode`](/language/functions/jsondecode) performs the opposite operation, _decoding_ |
| a JSON string to obtain its represented value. |
