EX294 Transform data with filters and plugins Practice Question

Which TWO filters are commonly used to manipulate JSON data in Ansible? (Select exactly two.)

⚠ Common exam trap

Many candidates confuse to_json and from_json, thinking both are used for manipulation, but to_json is for serialization (output) while from_json is for deserialization (input), and json_query is the actual manipulation filter for querying JSON data.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

from_json

(from_json) is correct because it converts a JSON string into an Ansible data structure (dict or list), enabling further manipulation with filters like json_query. This is essential when parsing API responses or configuration files that return JSON-formatted strings.
