to_json
Turns input into JSON, when possible. If input cannot be turned into JSON object, the filter just returns the input again.
Input:
1
{{ site | to_json }}Output:
1
{"id": 783, "content_type": { "name": "site", "title": "Site" }, "name": "A beautiful Site", ...}Input:
1
2
# params = { 'param_key_1' => 'param_val_1', 'param_key_2' => 'param_val_2' }
{{ params | to_json }}Output:
1
[["param_key_1", "param_val_1"], ["param_key_2", "param_val_2"]]When using to_json on a hash, a multidimensional array is returned (see above). If you want to convert a hash to key/value JSON, you can pass true as an argument. Plate Objects get converted to key/value JSON regardless of the passed argument.
Input:

# params = { 'param_key_1' => 'param_val_1', 'param_key_2' => 'param_val_2' }
{{ params | to_json: true }}Output:

{"param_key_1": "param_val_1", "param_key_2": "param_val_2"}
