Translate JSON file's specific field - json

Question

I would like to translate the field "text" from the flight domain of the Taskmaster-2 dataset. Which is a deeply nested JSON file. Using Google Cloud Translate how can I do it?
Example (from English to Bangla):
Origin JSON file:
[ {
"conversation_id": "dlg-00100680-00e0-40fe-8321-6d81b21bfc4f",
"instruction_id": "flight-12",
"utterances": [
{
"index": 0,
"speaker": "USER",
"text": "Hello. I'd like to find a round trip commercial airline flight from San Francisco to Denver.",
"segments": [
{
"start_index": 26,
"end_index": 36,
"text": "round trip",
"annotations": [
{
"name": "flight_search.type"
}
]
},
Output JSON file:
[ {
"conversation_id": "dlg-00100680-00e0-40fe-8321-6d81b21bfc4f",
"instruction_id": "flight-12",
"utterances": [
{
"index": 0,
"speaker": "USER",
"text": "হ্যালো. আমি সান ফ্রান্সিসকো থেকে ডেনভার পর্যন্ত একটি রাউন্ড ট্রিপ বাণিজ্যিক এয়ারলাইন ফ্লাইট খুঁজতে চাই।",
"segments": [
{
"start_index": 26,
"end_index": 36,
"text": "রাউন্ড ট্রিপ",
"annotations": [
{
"name": "flight_search.type"
}
]
},

I extracted a few lines of data in flights.json and used the code below written in Python using Google Cloud Translation API to translate English to Japanese. Also see list of supported languages of the API.
test.json:
[
{
"conversation_id": "dlg-00100680-00e0-40fe-8321-6d81b21bfc4f",
"instruction_id": "flight-12",
"utterances": [
{
"index": 0,
"speaker": "USER",
"text": "Hello. I'd like to find a round trip commercial airline flight from San Francisco to Denver.",
"segments": [
{
"start_index": 26,
"end_index": 36,
"text": "round trip",
"annotations": [
{
"name": "flight_search.type"
}
]
},
{
"start_index": 68,
"end_index": 81,
"text": "San Francisco",
"annotations": [
{
"name": "flight_search.origin"
}
]
},
{
"start_index": 85,
"end_index": 91,
"text": "Denver",
"annotations": [
{
"name": "flight_search.destination1"
}
]
}
]
},
{
"index": 1,
"speaker": "ASSISTANT",
"text": "Hello, how can I help you?"
},
{
"index": 2,
"speaker": "ASSISTANT",
"text": "San Francisco to Denver, got it.",
"segments": [
{
"start_index": 0,
"end_index": 13,
"text": "San Francisco",
"annotations": [
{
"name": "flight_search.origin"
}
]
},
{
"start_index": 17,
"end_index": 23,
"text": "Denver",
"annotations": [
{
"name": "flight_search.destination1"
}
]
}
]
}
]
}
]
Code:
import json
from google.cloud import translate_v2 as translate
f = open('test.json')
data = json.load(f)
target = "ja"
translate_client = translate.Client()
for conv in data:
for utt in conv["utterances"]:
utt["text"] = translate_client.translate(utt["text"], target_language=target)["translatedText"]
if "segments" in utt:
for seg in utt["segments"]:
seg["text"] = translate_client.translate(seg["text"], target_language=target)["translatedText"]
#print(data) # prints a dictionary
json_object = json.dumps(data, indent=2,ensure_ascii=False).encode('utf8')
print(json_object.decode()) # prints a json string
Output:
[

"conversation_id": "dlg-00100680-00e0-40fe-8321-6d81b21bfc4f",
"instruction_id": "flight-12",
