Whats the best way to extract key/values from a json file using grep/sed/awk.Or should I just use jq?

Grep exclusively uses regular expressions, which cannot parse recursive grammars such as JSON. You can probably write a JSON parser using sed or awk, but the sed/awk program will likely be comparatively large and unwieldy.

Use jq or some other tool/library specifically designed for parsing JSON.
